-This agent library can be used to track garbage collection events.

-You can use this agent library as follows:
-
- java -agentlib:gctest ...

-To get help on the available options try:

-The Events JVMTI_EVENT_GARBAGE_COLLECTION_START,
-JVMTI_EVENT_GARBAGE_COLLECTION_FINISH, and JVMTI_EVENT_OBJECT_FREE
-all have limitations as to what can be called directly inside the
-agent callback functions (e.g. no JNI calls are allowed, and limited

-watcher thread, this agent demonstrates how these limitations can be
-easily avoided, allowing the watcher thread to do just about anything
-after the JVMTI_EVENT_GARBAGE_COLLECTION_FINISH event.

-This agent library can be used to track object allocations.
-It uses the same java_crw_demo library used by HPROF to do BCI
-on all classfiles loaded into the Virtual Machine.
-
-You can use this agent library as follows:
-
- java -agentlib:heapTracker ...
-
-To get help on the available options try:
-
- java -agentlib:heapTracker=help
-
-See ${JAVA_HOME}/demo/jvmti/index.html for help running and building agents.

-heapViewer
-
-This agent library demonstrates how to get an easy view of the
-heap in terms of total object count and space used.
-It uses GetLoadedClasses(), SetTag(), and IterateThroughHeap()
-to count up all the objects of all the current loaded classes.
-The heap dump will happen at the event JVMTI_EVENT_VM_DEATH, or the
-event JVMTI_EVENT_DATA_DUMP_REQUEST.
-
-It also demonstrates some more robust agent error handling using
-GetErrorName(),
-
-Using the heap iterate functions, lots of statistics can be generated
-without resorting to using Byte Code Instrumentation (BCI).
-
-You can use this agent library as follows:
-
- java -agentlib:heapViewer ...
-
-To get help on the available options try:
-
- java -agentlib:heapViewer=help
-
-See ${JAVA_HOME}/demo/jvmti/index.html for help running and building agents.

-<h1>JVM TI Demonstration Code</h1>
-
-<p>
-The
-Java™ Virtual Machine Tools Interface (JVM TI)
-is a native tool interface provided in JDK 5.0 and newer.
-Native libraries that use JVM TI and are loaded into the
-Java Virtual Machine
-via the -agentlib, -agentpath, or -Xrun (deprecated) interfaces, are
-called Agents.
-<p>
-<A HREF="http://java.sun.com/j2se/latest/docs/guide/jvmti">JVM TI</A>
-was designed to work with the
-Java Native Interface
-(<A HREF="http://java.sun.com/j2se/latest/docs/guide/jni">JNI</A>),
-and eventually displace the
-Java Virtual Machine Debugging Interface
-(<A HREF="http://java.sun.com/j2se/1.5.0/docs/guide/jpda/jvmdi-spec.html">JVMDI</A>)
-and the
-Java Virtual Machine Profiling Interface
-(<A HREF="http://java.sun.com/j2se/1.5.0/docs/guide/jvmpi/index.html">JVMPI</A>).
-
-<p>
-We have created a set of demonstration agents that should
-help show many of the features and abilities of the
-interface. This list of demonstration agents will change over time.
-They are provided as educational tools and as starting
-points for Java tool development.
-
-<p>
-These agents are built with every JDK build and some basic testing is performed
-on a regular basis, but no extensive testbases currently
-exist for these agents.
-Every JDK installation should include all the pre-built binaries and sources for
-all these agents, just look in the demo/jvmti directory of your JDK.
-
-
-<h2>Using or Running These Agents</h2>
-
-<p>
-Using these agents will require the VM to locate the shared library file
-before any actual Java code is run.
-The JDK installation should contain all the agent libraries in
-the ${JAVA_HOME}/demo/jvmti/<i>agent-name</i>/lib directories.
-The Solaris 64bit version would be contained in the sparcv9 or amd64
-subdirectory.
-If 'java' complains that it can't find the library,
-you may need to add the directory containing the library into the
-LD_LIBRARY_PATH environment variable (Unix), or the PATH environment
-variable (Windows).
-This is system and platform specific.
-If you are using 64bit Solaris (e.g. 'java -d64'),
-you should use LD_LIBRARY_PATH64.
-Some agents such as the jdwp (debugger backend)
-are located inside the primary JDK directories and will always be found
-in those locations.
-
-<p>
-The agents that instrument classfiles
-(i.e. BCI, usually through the java_crw_demo library)
-such as heapTracker, mtrace, and minst,
-also need to have the Java classes they use available in the bootclasspath.
-The agents will make attempts at automatically adding their jar file
-(e.g. heapTracker.jar, mtrace.jar, or minst.jar) to the bootclasspath
-with AddToBootstrapClassLoaderSearch from JVM TI at startup
-(see the agent_util code).
-This is done by locating this jar file at
-${JAVA_HOME}/demo/jvmti/<i>agent-name</i>
-where JAVA_HOME is obtained by calling GetSystemProperty from JVM TI
-with "java.home".
-We recognize that this is not ideal, but felt that as just demonstration
-code it was acceptable.
-Ideally the agent could find out the actual directory it came from and
-locate the jar file relative to that location.
-Our demonstration agents currently do not do this.
-
-<p>
-If you choose to modify or change these agents, the above information
-is important in making everything is found.
-It is recommended that you change the name of the agent when you
-modify it to avoid conflicts with the existing demo agents.
-Or better yet, go to http://jdk.dev.java.net and submit your
-changes to the agent as an RFE to the JDK.
-
-
-<h2> Demonstration Agents Available </h2>
-
-<ul>
-
-<li>
-<A HREF="versionCheck">versionCheck</A>
-<br>
-This is a extremely small agent that does nothing but check the
-version string supplied in the jvmti.h file, with the version
-number supplied by the VM at runtime.
-</li>
-
-<li>
-<A HREF="compiledMethodLoad">compiledMethodLoad</A>
-<br>
-This is a small agent that traces CompiledMethodLoad events along
-with the HotSpot specific compile_info parameter.
-</li>
-
-<li>
-<A HREF="mtrace">mtrace</A>

-<h2>Agent Support</h2>
-
-<ul>
-
-<li>
-<A HREF="java_crw_demo">java_crw_demo</A>
-<br>
-This is a demo C library that does class file to class file
-transformations or BCI (Bytecode Instrumentation).
-It is used by several of the above agents.
-</li>
-
-
-</ul>
-
-
-
-<h2>Native Library Build Hints</h2>
-
-<p>
-All libraries loaded into java are assumed to be MT-safe (Multi-thread safe).
-This means that multiple threads could be executing the code at the same
-time, and static or global data may need to be placed in critical
-sections. See the Raw Monitor interfaces for more information.
-
-<p>
-All native libraries loaded into the
-Java Virtual Machine,
-including Agent libraries,
-need to be compiled and built in a compatible way.
-Certain native compilation options or optimizations should be avoided,
-and some are required.
-More information on this options is available in the man pages for
-the various compilers.
-
-<p>
-Some native compiler and linker options can create fatal or
-erroneous behavior when native agent libraries are operating
-inside the Java Virtual Machine.
-It would take too many words to describe all the possible issues with all
-the native compiler options, optimizations, and settings.
-Here are some recommendations on the basic compiler and linker options
-we recommend:
-
-<ul>
-
-<h3> Solaris </h3>
-
-<li>
-On Solaris, using the Sun Studio 11 C compiler,
-the typical compile and link command lines might look something like:
-<br>
-For 32bit SPARC:
-<br>
-<code><ul>
-cc -xO2 -mt -xregs=no%appl -xmemalign=4s -xarch=v8 -KPIC -c <i>*.c</i>
-<br>
-cc -mt -xarch=v8 -z defs -ztext -G -o <i>libXXX.so *.o</i> -lc
-</code></ul>
-<br>
-For 64bit SPARC:
-<br>
-<code><ul>
-cc -xO2 -mt -xregs=no%appl -xarch=v9 -KPIC -c <i>*.c</i>
-<br>
-cc -mt -xarch=v9 -z defs -ztext -G -o <i>libXXX.so *.o</i> -lc
-</code></ul>
-<br>
-For X86:
-<br>
-<code><ul>
-cc -xO2 -mt -xregs=no%frameptr -KPIC -c <i>*.c</i>
-<br>
-cc -mt -z defs -ztext -G -o <i>libXXX.so *.o</i> -lc
-</code></ul>
-<br>
-For AMD64:
-<br>
-<code><ul>
-cc -xO2 -mt -xregs=no%frameptr -xarch=amd64 -KPIC -c <i>*.c</i>
-<br>
-cc -mt -xarch=amd64 -z defs -ztext -G -o <i>libXXX.so *.o</i> -lc
-</code></ul>
-<br>
-</li>
-
-<li>
-Architecture/File Format:
-For SPARC 32bit use <code>-xarch=v8</code>,
-for SPARC 64bit use <code>-xarch=v9</code>,
-for X86 (32-bit)
-<i>
-leave the option off or use <code>-xarch=generic</code>
-</i>,
-and for AMD64 (64bit) use <code>-xarch=amd64</code>
-with both C and C++.
-<br>
-This is to be specific as to the architecture and the file format
-of the .o files (and ultimately of the .so).
-</li>
-
-<li>
-MT-Safe, Position Independent: Use <code>-KPIC -mt</code>
-with both C and C++.
-</li>
-
-<li>
-Register usage: For SPARC (both 32bit and 64bit) use
-<code>-xregs=no%appl</code> and for X86 and AMD64 use <code>-xregs=no%frameptr</code>
-with both C and C++.
-</li>
-
-<li>
-Alignment: For SPARC 32bit use -xmemalign=4s and for SPARC 64bit do NOT use <code>-xmemalign=4</code>
-with both C and C++.
-</li>
-
-<li>
-Dependencies: Use <code>ldd -r <i>LibraryName</i></code>.
-<br>
-After the shared library has been built, the utility
-<code>ldd</code> can be used to verify that all dependent libraries
-have been satisfied, and all externs can be found.
-If <code>ldd</code> says anything is missing, it is very likely that the JVM will also
-be unable to load this library.
-This usually means that you missed some <code>-l<i>name</i></code>
-options when building the library, or perhaps forgot a <code>-R path</code>
-option that tells the library where to look for libraries at runtime.
-</li>
-
-<h3> Linux </h3>
-
-<li>
-On Linux, using the gcc version 3.2,
-the typical compile and link command lines might look something like:
-<br>
-For X86:
-<br>
-<code><ul>
-gcc -O2 -fPIC -pthread -DLINUX -c <i>*.c</i>
-<br>
-gcc -z defs -static-libgcc -shared -o <i>libXXX.so *.o</i> -lc
-</code></ul>
-<br>
-For AMD64:
-<br>
-<code><ul>
-gcc -O2 -fPIC -pthread -DLINUX -D_LP64=1 -c <i>*.c</i>
-<br>
-gcc -z defs -static-libgcc -shared -o <i>libXXX.so *.o</i> -lc
-</code></ul>
-<br>
-</li>
-
-<li>
-MT-Safe, Position Independent:
-Use <code>-fPIC -pthread</code>.
-</li>
-
-<li>
-Agent Demo Code: Needs -DLINUX
-</li>
-
-<li>
-Register Usage: Use <code>-fno-omit-frame-pointer</code>.
-<br>
-It is important that these libraries have frame pointer register usage, see the above comments on the Solaris
-<code>-xregs=no%frameptr</code>
-option.
-</li>
-
-<li>
-Library: Use -static-libgcc.
-<br>
-When building the shared library (-shared option), this option
-allows for maximum portability of the library between different
-flavors of Linux.
-The problem we have seen with Linux is that we cannot depend
-on a compatible shared gcc library existing on all the versions of
-Linux we can run on.
-By doing this static link, the version script becomes more
-important, making sure you don't expose any extern symbols
-you didn't intend to.
-</li>
-
-<li>
-Dependencies: Use <code>ldd -r <i>LibraryName</i></code>.
-<br>
-Provides the same checking as Solaris (see above).
-</li>
-
-<h3> Windows </h3>
-
-<li>
-On Windows and using the Microsoft C++ Compiler Visual Studio .NET 2003,
-the typical compile and link command lines might look something like:
-<br>
-For X86:
-<br>
-<code><ul>
-cl /O1 /MD /D _STATIC_CPPLIB /c <i>*.c</i>
-<br>
-link /dll /opt:REF /out:<i>XXX.dll *.obj</i>
-</code></ul>
-<br>
-For AMD64:
-<br>
-<code><ul>
-cl /O1 /MD /D _STATIC_CPPLIB /c <i>*.c</i>
-<br>
-link /dll /opt:REF /out:<i>XXX.dll *.obj</i>
-</code></ul>
-<br>
-</li>
-
-<li>
-Library: Use <code>/opt:REF </code> when building the dll.
-</li>
-
-<li>
-MS DLL Runtime: Use the <code>/MD /D _STATIC_CPPLIB</code> option.
-<br>
-This causes your dll to become dependent on just MSVCR*.DLL.
-The option /D _STATIC_CPPLIB prevents you from becoming dependent on the
-C++ library MSVCP*.DLL.
-This is what we use in the JDK, but there are probably many combinations
-that you could safely use, unfortunately there are many combinations
-of runtimes that will not work.
-Check the Microsoft site on proper use of runtimes.
-</li>
-
-<li>
-Dependencies: Use VC++ <code>dumpbin /exports</code> and the VC++ "Dependency Walker".
-<br>
-Provides dependency information similar to <code>ldd</code>.
-</li>
-
-</ul>

-java_crw_demo Library
-
-The library java_crw_demo is a small C library that is used by HPROF
-and other agent libraries to do some very basic bytecode
-insertion (BCI) of class files. This is not an agent
-library but a general purpose library that can be used to do some
-very limited bytecode insertion.
-
-In the demo sources, look for the use of java_crw_demo.h and
-the C function java_crw_demo(). The java_crw_demo library is provided
-as part of the JRE.
-
-The basic BCI that this library does includes:
-
- * On entry to the java.lang.Object init method (signature "()V"),
- a invokestatic call to tclass.obj_init_method(object); is inserted.
-
- * On any newarray type opcode, immediately following it, the array
- object is duplicated on the stack and an invokestatic call to
- tclass.newarray_method(object); is inserted.
-
- * On entry to all methods, a invokestatic call to
- tclass.call_method(cnum,mnum); is inserted. The agent can map the
- two integers (cnum,mnum) to a method in a class, the cnum is the
- number provided to the java_crw_demo library when the classfile was
- modified.
-
- * On return from any method (any return opcode), a invokestatic call to
- tclass.return_method(cnum,mnum); is inserted.
-
-Some methods are not modified at all, init methods and finalize methods
-whose length is 1 will not be modified. Classes that are designated
-"system" will not have their clinit methods modified. In addition, the
-method java.lang.Thread.currentThread() is not modified.
-
-No methods or fields will be added to any class, however new constant
-pool entries will be added at the end of the original constant pool table.
-The exception, line, and local variable tables for each method is adjusted
-for the modification. The bytecodes are compressed to use smaller offsets
-and the fewest 'wide' opcodes.
-
-All attempts are made to minimize the number of bytecodes at each insertion
-site, however, classes with N return opcodes or N newarray opcodes will get
-N insertions. And only the necessary modification dictated by the input
-arguments to java_crw_demo are actually made.

-This agent library can be used to inject code at method calls.
-It uses the same java_crw_demo library used by HPROF to do BCI on all
-or selected classfiles loaded into the Virtual Machine.
-The class Minst.java can be customized to do whatever you wish,
-within reason of course, and does not call native methods directly.
-
-You can use this agent library as follows:
-
- java -agentlib:minst ...
-
-To get help on the available options try:
-
- java -agentlib:minst=help
-
-See ${JAVA_HOME}/demo/jvmti/index.html for help running and building agents.

-mtrace
-
-This agent library can be used to track method call and return counts.
-It uses the same java_crw_demo library used by HPROF to do BCI on all or
-selected classfiles loaded into the Virtual Machine. It will print out a
-sorted list of the most heavily used classes (as determined by the number
-of method calls into the class) and also include the call and return counts
-for all methods that are called.
-
-You can use this agent library as follows:
-
- java -Xbootclasspath/a:mtrace.jar -agentlib:mtrace ...
-
-To get help on the available options try:
-
- java -agentlib:mtrace=help
-
-See ${JAVA_HOME}/demo/jvmti/index.html for help running and building agents.

-FullThreadDump demonstrates the use of the java.lang.management API
-to print the full thread dump. JDK 6 defines a new API to dump
-the information about monitors and java.util.concurrent ownable
-synchronizers.
-
-This demo also illustrates how to monitor JDK 5 and JDK 6 VMs with
-two versions of APIs.
-
-It contains two parts:
-a) Local monitoring within the application
-b) Remote monitoring by connecting to a JMX agent with a JMX service URL:
- service:jmx:rmi:///jndi/rmi://<hostName>:<portNum>/jmxrmi
- where <hostName> is the hostname and <portNum> is the port number
- to which the JMX agent will be connected.
-
-To run the demo
----------------
-a) Local Monitoring
-
- java -cp <JDK_HOME>/demo/management/FullThreadDump/FullThreadDump.jar Deadlock
-
- This will dump the stack trace and then detect deadlocks locally
- within the application.
-
-b) Remote Monitoring
-
- (1) Start the Deadlock application (or any other application)
- with the JMX agent as follows:
-
- java -Dcom.sun.management.jmxremote.port=1090
- -Dcom.sun.management.jmxremote.ssl=false
- -Dcom.sun.management.jmxremote.authenticate=false
- -cp <JDK_HOME>/demo/management/FullThreadDump/FullThreadDump.jar
- Deadlock
-
- This instruction uses the Sun's built-in support to enable a JMX agent.
- You can programmatically start a JMX agent with the RMI connector
- using javax.management.remote API. See the javadoc and examples for
- javax.management.remote API for details.
-
- (2) Run FullThreadDump
-
- java -jar <JDK_HOME>/demo/management/FullThreadDump/FullThreadDump.jar \
- localhost:1090
-
- This will dump the stack trace and then print out the deadlocked threads.
-
-These instructions assume that this installation's version of the java
-command is in your path. If it isn't, then you should either
-specify the complete path to the java command or update your
-PATH environment variable as described in the installation
-instructions for the Java(TM) SDK.

-JTop monitors the CPU usage of all threads in a remote application
-which has remote management enabled. JTop demonstrates the use of
-the java.lang.management API to obtain the CPU consumption for
-each thread.
-
-JTop is also a JConsole Plugin. See below for details.
-
-JTop Standalone GUI
-===================
-
-JTop first establishes a connection to a JMX agent in a remote
-application with a JMX service URL:
- service:jmx:rmi:///jndi/rmi://<hostName>:<portNum>/jmxrmi
-
-where <hostName> is the hostname and <portNum> is the port number
-to which the JMX agent will be connected.
-
-To run the demo
----------------
-(1) Start the application with the JMX agent - here's an example of
- how the Java2D is started
-
- java -Dcom.sun.management.jmxremote.port=1090
- -Dcom.sun.management.jmxremote.ssl=false
- -Dcom.sun.management.jmxremote.authenticate=false
- -jar <JDK_HOME>/demo/jfc/Java2D/Java2Demo.jar
-
- This instruction uses the Sun's built-in support to enable a JMX agent
- with a JMX service URL as described above.
- You can programmatically start a JMX agent with the RMI connector
- using javax.management.remote API. See the javadoc and examples for
- javax.management.remote API for details.
-
-(2) Run JTop on a different machine:
-
- java -jar <JDK_HOME>/demo/management/JTop/JTop.jar <hostname>:1090
-
- where <hostname> is where the Java2Demo.jar runs in step (1).
-
-These instructions assume that this installation's version of the java
-command is in your path. If it isn't, then you should either
-specify the complete path to the java command or update your
-PATH environment variable as described in the installation
-instructions for the Java(TM) SDK.
-
-JTop JConsole Plugin
-====================
-
-JTop is a JConsole Plugin which adds a "JTop" tab to JConsole.
-
-To run JConsole with the JTop plugin
-------------------------------------
- jconsole -pluginpath <JDK_HOME>/demo/management/JTop/JTop.jar
-
-
-To compile
-----------
- javac -classpath <JDK_HOME>/lib/jconsole.jar JTopPlugin.java
-
-com.sun.tools.jconsole API is in jconsole.jar which is needed
-in the classpath for compilation.

-VerboseGC demonstrates the use of the java.lang.management API to
-print the garbage collection statistics and memory usage remotely
-by connecting to a JMX agent with a JMX service URL:
- service:jmx:rmi:///jndi/rmi://<hostName>:<portNum>/jmxrmi
-where <hostName> is the hostname and <portNum> is the port number
-to which the JMX agent will be connected.
-
-To run the VerboseGC demo
-
-(1) Start the application with the JMX agent - here's an example of
- how the Java2D is started
-
- java -Dcom.sun.management.jmxremote.port=1090
- -Dcom.sun.management.jmxremote.ssl=false
- -Dcom.sun.management.jmxremote.authenticate=false
- -jar <JDK_HOME>/demo/jfc/Java2D/Java2Demo.jar
-
- This instruction uses the Sun's built-in support to enable a JMX agent.
- You can programmatically start a JMX agent with the RMI connector
- using javax.management.remote API. See the javadoc and examples for
- javax.management.remote API for details.
-
-(2) Run VerboseGC
-
- java -jar <JDK_HOME>/demo/management/VerboseGC/VerboseGC.jar localhost:1090
-
-These instructions assume that this installation's version of the java
-command is in your path. If it isn't, then you should either
-specify the complete path to the java command or update your
-PATH environment variable as described in the installation
-instructions for the Java(TM) SDK.

-What is this demo about?
-
-This is "script shell" plugin for jconsole - the monitoring and management
-client tool shipped with JRE. This plugin adds "Script Shell" tab to jconsole.
-This serves as a demo for jconsole plugin API (com.sun.tools.jconsole) as well
-as a demo for scripting API (javax.script) for the Java platform.
-
-Script console is an interactive read-eval-print interface that can be used
-used to execute advanced monitoring and management queries. By default,
-JavaScript is used as the scripting language. The scripting language can be
-changed using the system property com.sun.demo.jconsole.console.language. To
-use other scripting languages, you need to specify the corresponding engine
-jar file in pluginpath along with this plugin's jar file.
-
-The following 3 global variables are exposed to the script engine:
-
- window javax.swing.JPanel
- engine javax.script.ScriptEngine
- plugin com.sun.tools.jconsole.JConsolePlugin
-
-If you use JavaScript, there are many useful global functions defined in
-./src/resources/jconsole.js. This is built into the script plugin jar file.
-In addition, you can add other global functions and global variables by
-defining those in ~/jconsole.js (or jconsole.<ext> where <ext> is the file
-extension for your scripting language of choice under your home directory).
-
-How do I compile script console plugin?
-
-You can use the Java based build tool "ant" (http://ant.apache.org) to build
-this plugin. To build using ant, please use the following command in the
-current directory:
-
- ant
-
-How do I use script console plugin?
-
-To start jconsole with this plugin, please use the following command
-
- jconsole -pluginpath jconsole-plugin.jar
-
-How do I load my own script files in script console?
-
-If you use JavaScript (the default), then there is a global function called
-"load" to load any script file from your file system. In script console
-prompt, enter the following:
-
- load(<script-file-path>);
-
-where <script-file-path> is the path of your script file to load. If you don't
-specify the file path, then the load function shows file dialog box to choose
-the script file to load.
-
-How do I get help on script global functions?
-
-If you use JavaScript (the default), then there is a global function called
-"help" that prints one-line help messages on global functions. In script
-console prompt, enter the following:
-
- help();
-
-Where are the sample JavaScript files?
-
-./src/scripts directory contains JavaScript files that can be loaded into
-script console.

- **********************************************************************
- * Poller.c :
- * JNI code for use with Poller.java, principally to take advantage
- * of poll() or /dev/poll multiplexing.
- *
- * One will need Solaris 8 or Solaris 7 with adequate patches to take
- * advantage of the /dev/poll performance enhancements, though any
- * version of Solaris 7 will automatically use the kernel poll()
- * caching. And poll() will function in 2.5.1 and 2.6 as well, but
- * will not perform well for large numbers of file descriptors.
- *
- * Several assumptions have been made to simplify this code :
- * 1> At most MAX_HANDLES (32) separate pollable entities are currently
- * supported.
- * 2> Global synchronization from Java is assumed for all init, create
- * and destroy routines. Per Object (handle passed in) synchronization
- * is required for all AddFd, RemoveFd, IsMember, and Wait routines.
- * 3> It is currently up to the user to handle waking up an
- * existing nativeWait() call to do an addfd or removefd on
- * that set...could implement that here with an extra pipe, or
- * with a pair of loopback sockets in Poller.java or user code.
- * In most cases interruption is not necessary for deletions,
- * so long as deletions are queued up outside the Poller class
- * and then executed the next time waitMultiple() returns.
- * 4> /dev/poll performance could be slightly improved by coalescing
- * adds/removes so that a write() is only done before the ioctl
- * (DP_POLL), but this complicates exception handling and sees
- * only modest performance gains so wasn't done.
- * 5> /dev/poll does not report errors on attempts to remove non-
- * extant fds, but a future bug fix to the /dev/poll device driver
- * should solve this problem.
- * 6> Could add simpler code for pre-Solaris 7 releases which will
- * perform slightly better on those OSs. But again there
- * are only modest gains to be had from these new code paths,
- * so they've been omitted here.
- *
- * Compile "cc -G -o <dest_dir>/libpoller.so -I ${JAVA_HOME}/include " \
- * -I ${JAVA_HOME}/include/solaris Poller.c" and place the <dest_dir>
- * in your LD_LIBRARY_PATH

-
-This Poller class demonstrates access to poll(2) functionality in Java.
-
-Requires Solaris production (native threads) JDK 1.2 or later, currently
-the C code compiles only on Solaris (SPARC and Intel).
-
-Poller.java is the class, Poller.c is the supporting JNI code.
-
-PollingServer.java is a sample application which uses the Poller class
-to multiplex sockets.
-
-SimpleServer.java is the functional equivalent that does not multiplex
-but uses a single thread to handle each client connection.
-
-Client.java is a sample application to drive against either server.
-
-To build the Poller class and client/server demo :
- javac PollingServer.java Client.java
- javah Poller
- cc -G -o libpoller.so -I ${JAVA_HOME}/include -I ${JAVA_HOME}/include/solaris\
- Poller.c
-
-You will need to set the environment variable LD_LIBRARY_PATH to search
-the directory containing libpoller.so.
-
-To use client/server, bump up your fd limit to handle the connections you
-want (need root access to go beyond 1024). For info on changing your file
-descriptor limit, type "man limit". If you are using Solaris 2.6
-or later, a regression in loopback read() performance may hit you at low
-numbers of connections, so run the client on another machine.
-
-BASICs of Poller class usage :
- run "javadoc Poller" or see Poller.java for more details.
-
-{
- Poller Mux = new Poller(65535); // allow it to contain 64K IO objects
-
- int fd1 = Mux.add(socket1, Poller.POLLIN);
- ...
- int fdN = Mux.add(socketN, Poller.POLLIN);
-
- int[] fds = new int[100];
- short[] revents = new revents[100];
-
- int numEvents = Mux.waitMultiple(100, fds, revents, timeout);
-
- for (int i = 0; i < numEvents; i++) {
- /*
- * Probably need more sophisticated mapping scheme than this!
- */
- if (fds[i] == fd1) {
- System.out.println("Got data on socket1");
- socket1.getInputStream().read(byteArray);
- // Do something based upon state of fd1 connection
- }
- ...
- }
-}
-
-Poller class implementation notes :
-
- Currently all add(),remove(),isMember(), and waitMultiple() methods
-are synchronized for each Poller object. If one thread is blocked in
-pObj.waitMultiple(), another thread calling pObj.add(fd) will block
-until waitMultiple() returns. There is no provided mechanism to
-interrupt waitMultiple(), as one might expect a ServerSocket to be in
-the list waited on (see PollingServer.java).
-
- One might also need to interrupt waitMultiple() to remove()
-fds/sockets, in which case one could create a Pipe or loopback localhost
-connection (at the level of PollingServer) and use a write() to that
-connection to interrupt. Or, better, one could queue up deletions
-until the next return of waitMultiple(). Or one could implement an
-interrupt mechanism in the JNI C code using a pipe(), and expose that
-at the Java level.
-
- If frequent deletions/re-additions of socks/fds is to be done with
-very large sets of monitored fds, the Solaris 7 kernel cache will
-likely perform poorly without some tuning. One could differentiate
-between deleted (no longer cared for) fds/socks and those that are
-merely being disabled while data is processed on their behalf. In
-that case, re-enabling a disabled fd/sock could put it in it's
-original position in the poll array, thereby increasing the kernel
-cache performance. This would best be done in Poller.c. Of course
-this is not necessary for optimal /dev/poll performance.
-
- Caution...the next paragraph gets a little technical for the
-benefit of those who already understand poll()ing fairly well. Others
-may choose to skip over it to read notes on the demo server.
-
- An optimal solution for frequent enabling/disabling of socks/fds
-could involve a separately synchronized structure of "async"
-operations. Using a simple array (0..64k) containing the action
-(ADD,ENABLE,DISABLE, NONE), the events, and the index into the poll
-array, and having nativeWait() wake up in the poll() call periodically
-to process these async operations, I was able to speed up performance
-of the PollingServer by a factor of 2x at 8000 connections. Of course
-much of that gain was from the fact that I could (with the advent of
-an asyncAdd() method) move the accept() loop into a separate thread
-from the main poll() loop, and avoid the overhead of calling poll()
-with up to 7999 fds just for an accept. In implementing the async
-Disable/Enable, a further large optimization was to auto-disable fds
-with events available (before return from nativeWait()), so I could
-just call asyncEnable(fd) after processing (read()ing) the available
-data. This removed the need for inefficient gang-scheduling the
-attached PollingServer uses. In order to separately synchronize the
-async structure, yet still be able to operate on it from within
-nativeWait(), synchronization had to be done at the C level here. Due
-to the new complexities this introduced, as well as the fact that it
-was tuned specifically for Solaris 7 poll() improvements (not
-/dev/poll), this extra logic was left out of this demo.
-
-
-Client/Server Demo Notes :
-
- Do not run the sample client/server with high numbers of connections
-unless you have a lot of free memory on your machine, as it can saturate
-CPU and lock you out of CDE just by its very resource intensive nature
-(much more so the SimpleServer than PollingServer).
-
- Different OS versions will behave very differently as far as poll()
-performance (or /dev/poll existence) but, generally, real world applications
-"hit the wall" much earlier when a separate thread is used to handle
-each client connection. Issues of thread synchronization and locking
-granularity become performance killers. There is some overhead associated
-with multiplexing, such as keeping track of the state of each connection; as
-the number of connections gets very large, however, this overhead is more
-than made up for by the reduced synchronization overhead.
-
- As an example, running the servers on a Solaris 7 PC (Pentium II-350 x
-2 CPUS) with 1 GB RAM, and the client on an Ultra-2, I got the following
-times (shorter is better) :
-
- 1000 connections :
-
-PollingServer took 11 seconds
-SimpleServer took 12 seconds
-
- 4000 connections :
-
-PollingServer took 20 seconds
-SimpleServer took 37 seconds
-
- 8000 connections :
-
-PollingServer took 39 seconds
-SimpleServer took 1:48 seconds
-
- This demo is not, however, meant to be considered some form of proof
-that multiplexing with the Poller class will gain you performance; this
-code is actually very heavily biased towards the non-polling server as
-very little synchronization is done, and most of the overhead is in the
-kernel IO for both servers. Use of multiplexing may be helpful in
-many, but certainly not all, circumstances.
-
- Benchmarking a major Java server application which can run
-in a single-thread-per-client mode or using the new Poller class showed
-Poller provided a 253% improvement in throughput at a moderate load, as
-well as a 300% improvement in peak capacity. It also yielded a 21%
-smaller memory footprint at the lower load level.
-
- Finally, there is code in Poller.c to take advantage of /dev/poll
-on OS versions that have that device; however, DEVPOLL must be defined
-in compiling Poller.c (and it must be compiled on a machine with
-/usr/include/sys/devpoll.h) to use it. Code compiled with DEVPOLL
-turned on will work on machines that don't have kernel support for
-the device, as it will fall back to using poll() in those cases.
-Currently /dev/poll does not correctly return an error if you attempt
-to remove() an object that was never added, but this should be fixed
-in an upcoming /dev/poll patch. The binary as shipped is not built with
-/dev/poll support as our build machine does not have devpoll.h.

-<h2>Repeating Annotations Demo</h2>
-
-<p>
- This demo shows how to use repeating annotations at runtime and at compile time.
-</p>
-
-<ul>
- <li><h3>Dependency checker.</h3>
-
- <p>
- Shows how to define repeating annotations and process them at compile time.
- The problem domain is some code that performs useful operations on hardware devices.
- The code relies on "modules" to be present on the devices. Applicability of the code to a particular
- device is checked while compiling the code for a particular device.
- A set of modules provided by a device is listed in an xml file that turns red during the compilation
- phase and is compared with the required module set specified by annotations.
- For instance, there is kettle with hardware modules: thermometer, display, and clock.
- There is also a boiler plug-in that requires clock, thermometer, heater, and optionally an LED light.
-
- Build the PluginChecker annotation processor first.
- Then, run javac with the annotation processor against plug-in sources using the following command: </p>
-
- <code>javac -cp "PluginChecker.jar" -processor checker.PluginChecker -Adevice=Kettle.xml -proc:only <source
- files></code>
-
- <p>
- where <code>PluginChecker.jar</code> - path to jar file that contains PluginChecker annotation processor
- class. </br>
- <code>Kettle.xml</code> - path to device descriptor Kettle.xml </br>
- <code><source files></code> - source files in Plugins/src
- </p>
- For more information, see the source files.
- </p>
- <ul>
- <li>Annotation processor sources: <a href="DependencyChecker/PluginChecker/src/">DependencyChecker/PluginChecker/src</a>
- <li>Processing of repeating annotations can be found in <a href="DependencyChecker/PluginChecker/src/checker/PluginChecker.java">PluginChecker.java</a>
- <li>Usage of repeating annotation is shown in modules sources.<a href="DependencyChecker/Plugins/src">DependencyChecker/Plugins/src</a>
- </ul>
-
- <li><h3>Validator.</h3>
-
- <p>
- Shows how to define repeating annotations and process them at runtime.
- A problem domain is code that needs to validate provided Suppliers for conformance to some criteria.
- The criteria are implemented by the Validator class which is applied by using annotations that are placed in
- the code whenever validation is needed. For more information, see the
- source files.
- </p>
-
- <p>
- <ul>
- <li>Usage of repeating annotation is described in <a href="Validator/src/PositiveIntegerSupplier.java">PositiveIntegerSupplier.java</a>
- <li> Example of how to define a repeating annotation type can be found in
- <a href="Validator/src/Validate.java">Validate.java</a>
- <li> Usages of the new reflective methods can be found in <a href="Validator/src/SupplierValidator.java">SupplierValidator.java</a>

- <title>JMX™ "scandir" Example</title>
- </head>
- <body>
-
- <h1><center>Java™ Management Extensions (JMX™) <i>scandir</i> Example</center></h1>
-
- <h2><a name="h2-Introduction">Introduction</a></h2>
- <ul>
- <p>The JMX <i>scandir</i> example is an application that
- scans parts of a filesystem - e.g. a set of directories
- used by a number of lab machines when running tests - in
- order to clean up and optimize disk space by removing
- obsolete files - e.g. files that are leaked by the test
- suites running on those machines, like coredump files, or
- temporary files that might remain after a test crash.
- It could also serve as a basis for an application that
- would monitor disk usage and suggest removal of old big
- long-unaccessed files.
- </p>
- <p>The JMX <i>scandir</i> example does not however implement
- the full fledged logic that such an application might
- have. It implements a subset of this logic which is
- sufficient to demonstrate common patterns and
- solutions used when implementing a monitoring and
- management interface for an application with JMX
- Technology.</p>
- <p>This example is an advanced JMX example, which presents
- advanced JMX concepts. It is assumed that the reader is already
- familiar with the JMX API. Newcomers to JMX Technology are
- invited to have a look at the <a
- href="http://java.sun.com/javase/6/docs/technotes/guides/jmx/"
- >JMX API Overview, Tutorial and Examples</a> before going any further.
- </p>

- <h2><a name="h2-Overview">Overview of the <i>scandir</i> Example</a></h2>
-
- <ul>
- <p>The JMX <i>scandir</i> example is built around the
- following MBeans:</p>
- <ul>
- <li>The first MBean we will present here is the
- <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/DirectoryScannerMXBean.html"
-title="A DirectoryScannerMXBean looks for file matching a given set of criteria, starting at a given root."
- >DirectoryScannerMXBean</a>. <br>A
- <code>DirectoryScannerMXBean</code> is an MBean that scans a
- file system starting at a given root directory, and then looks
- for files that match the given criteria. When such a file is
- found, the <code>DirectoryScannerMXBean</code> takes the
- action for which it was configured: emit a notification,
- <i>and/or</i> log a <code>record</code> for this file,
- <i>and/or</i> delete that file. The code that would actually
- delete the file is commented out - so that nothing valuable is
- lost if the example is run by mistake on the wrong set of
- directories.<br> <code>DirectoryScannerMXBeans</code> are
- created by the <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ScanManagerMXBean.html"
-title="The ScanManagerMXBean is the main MBean of the scandir application"
- >ScanManagerMXBean</a> - see next item on the list, from its
- configuration.
- </li>
- <li>
- The <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ScanManagerMXBean.html"
-title="The ScanManagerMXBean is the main MBean of the scandir application"
- >ScanManagerMXBean</a> is the actual entry point of the
- application. It reads the application's
- configuration, and from that configuration,
- will create a <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ResultLogManager.html"
-title="The ResultLogManager is in charge of managing result logs"
- >ResultLogManager</a> and some <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/DirectoryScannerMXBean.html"
-title="A DirectoryScannerMXBean looks for file matching a given set of criteria, starting at a given root."
- >DirectoryScannerMXBeans</a>.
- <br>The <code>ScanManagerMXBean</code> lets you start, stop, and
- schedule directory scans. The
- <code>ScanManagerMXBean</code> is a singleton
- MBean: there can be at most one instance of such
- an MBean registered in a given MBeanServer.
- </li>
- <li>The <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ScanDirConfigMXBean.html"
-title="The ScanDirConfigMXBean is in charge of the configuration"
- >ScanDirConfigMXBean</a> is an MBean which is able to
- load/save the configuration to/from an XML file. It
- will also let you modify that configuration - by e.g.
- creating new directory scanners in there.
- The corresponding MBeans will be created later, only
- when you later
- ask the <code><a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ScanManagerMXBean.html"
-title="The ScanManagerMXBean is the main MBean of the scandir application"
- >ScanManagerMXBean</a> </code> to apply the
- configuration again.<br>
- The <code>ScanDirConfigMXBean</code> is created by the
- <code>ScanManagerMXBean</code>, when the
- <code>ScanManagerMXBean</code> is registered.
- It is also possible to create an alternate
- <code>ScanDirConfigMXBean</code>, and to switch the
- <code>ScanDirConfigMXBean</code> to use one or the other
- configuration.
- <br>An example of XML configuration file is given
- <a href="src/etc/testconfig.xml"
- title="An Example Of Configuration"
- >here</a>. Although you could edit such a file by
- hand, it is easier to do it programmatically (or
- with <a href="#JConsole">JConsole</a>) through
- the <code>ScanDirConfigMXBean</code> interface.
- </li>
- <li>The <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ResultLogManagerMXBean.html"
-title="The ResultLogManagerMXBean is in charge of managing result logs"
- >ResultLogManagerMXBean</a> is in charge of managing result logs.
- <br>Directory Scanners can be configured to log a
- <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/config/ResultRecord.html"
-title="A ResultRecord contains information about a file matching the criteria of a Directory Scanner"
- >ResultRecord</a> whenever they take action upon a file that
- matches their criteria. The <code>ResultLogManagerMXBean</code> is
- responsible for logging these result records.
- The <code>ResultLogManagerMXBean</code> can be configured to log
- such records to a flat file, or into a log held in memory, or
- both. Both logs (file and memory) can be configured with a
- maximum capacity.
- <br>When the maximum capacity of the memory
- log is reached, its first entry (i.e. its oldest entry) is
- removed to make place for the latest one.
- <br>When the maximum
- capacity of the file log is reached, the file is
- renamed by appending a tilde '~' to its name and a
- new result log is created.
- <br>The <code>ResultLogManagerMXBean</code>
- will let you interactively clear these result logs, change their
- capacity, and decide where (memory or file) to log.
- The memory log is useful in that its content can be interactively
- returned by the <code>ResultLogManagerMXBean</code>, while
- the file log doesn't have this facility.<br>
- The result logs are intended to be used by e.g. an offline
- program that would take some actions on the files that
- matched the scan criteria:
- <br>The <i>scandir</i> application
- could be configured to only produce logs (i.e. takes no
- action but logging the matching files), and the real
- action could be performed by another program or module (e.g. mail the result log to the engineer who
- maintains the lab, or parse that log and delete all the
- files listed there, or parse the log and prepare and send
- a single mail to each owner of matching files, containing
- the list of files they should consider deleting).<br>
- The <code>ResultLogManagerMXBean</code> is a singleton
- MBean created by the <code><a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ScanManagerMXBean.html"
-title="The ScanManagerMXBean is the main MBean of the scandir application"
- >ScanManagerMXBean</a> </code>
- which reads and writes its configuration from the
- <code><a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ScanDirConfigMXBean.html"
-title="The ScanDirConfigMXBean is in charge of the configuration"
- >ScanDirConfigMXBean</a></code>.
- </li>
- </ul>
- <p>An application <code>main()</code> method is
- provided in the <a
- href="dist/javadoc/com/sun/jmx/examples/scandir/ScanDirAgent.html"
- >ScanDirAgent</a> class. The <code>main()</code> simply registers
- a <code><a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ScanManagerMXBean.html"
-title="The ScanManagerMXBean is the main MBean of the scandir application"
- >ScanManagerMXBean</a> </code> in the platform MBeanServer, and
- then waits for someone to call <code>close()</code> on the
- <code>ScanManagerMXBean</code>.
- </p>
- <p>When the <code>ScanManagerMXBean</code> is registered, it
- will create a default <code><a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ScanDirConfigMXBean.html"
-title="The ScanDirConfigMXBean is in charge of the configuration"
- >ScanDirConfigMXBean</a></code> bound
- to a default XML config file.
- </p>
- <p>The application's default XML config file is determined as
- follows:
- <ol>
- <li>If the property <code>scandir.config.file</code> is
- defined, the default application file will be the
- file pointed to by this property. If that file
- doesn't exist, it will be created when
- <code>ScanDirConfigMXBean.save()</code> is
- invoked.
- </li>
- <li>Otherwise the application config file is
- assumed to be a file called <code>jmx-scandir.xml</code>,
- located in the user's directory (as defined by
- the System property <code>user.home</code>).
- If that file doesn't exists, it will be created when
- <code>ScanDirConfigMXBean.save()</code> is
- invoked.
- </li>
- </ol>
- <p>It is worth noting that this project is defined to
- run with the following properties:
- <pre>-Djava.util.logging.config.file=logging.properties</pre>
- <pre>-Dscandir.config.file=src/etc/testconfig.xml</pre>
- With <code>ScanDirAgent</code> defined as the project's
- main class. Hence when you invoke from the NetBeans IDE
- <i>Run Project</i> on the <i>jmx-scandir</i> project,
- or <i>Run file</i> on the <code>ScanDirAgent</code>, the
- application starts with the test configuration provided in
- <a href="src/etc/testconfig.xml"

- <ul>
- <p>This section discusses some common patterns and
- design choices that this example demonstrates, and some pitfalls that
- it avoids.
- </ul>
- <h3>MBeans or MXBeans?</h3>
- <ul>
- <p>What is an MXBean? MXBeans made their appearance in
- J2SE 5.0 (Tiger), with the Management and Monitoring
- API of the JVM. However, Java SE 6 is the first
- Java SE release that contains a standard framework which
- makes it possible to create and register your own MXBeans.
- </p>
- <p>MXBeans are a special kind of MBean, which once registered
- in the MBeanServer, get automatically transformed into
- OpenMBeans. From a developer point of view, nothing changes:
- A Wombat MBean can become an MXBean simply by renaming
- its <code>WombatMBean</code> interface into <code>WombatMXBean</code>.</p>
- <p>Using MXBeans rather than plain Standard MBean brings its
- own advantages:</p>
- <ul>
- <li>
- Generic tools, like JConsole, will be able to
- display and interact with your MXBeans nicely, even
- if your MXBean interfaces reference custom types
- - e.g. custom Java enums. This is because all the types
- exposed by your MXBeans are converted to Open Types.
- Just look at the <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ScanDirConfigMXBean.html"
-title="The ScanDirConfigMXBean is in charge of the configuration"
- >ScanDirConfigMXBean</a> with JConsole and you will
- understand the benefits.
- </li>
- <li>
- When writing a programmatic client, you can obtain
- a proxy that implements the original MXBean interface,
- and forget about the Open Type conversion.
- The JUnit unit tests that come with this example
- use this feature very widely. Have a look at them.
- </li>
- <li>
- The MXBean framework also lets you nicely navigate
- from one MXBean to another: your MXBeans can
- have attributes and parameters which are proxies
- to other MXBeans! We demonstrate this in the
- <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ScanManagerMXBean.html"
-title="The ScanManagerMXBean is the main MBean of the scandir application"
- >ScanManagerMXBean</a> which exposes a list
- of <code><a
-href="dist/javadoc/com/sun/jmx/examples/scandir/DirectoryScannerMXBean.html"
-title="A DirectoryScannerMXBean looks for file matching a given set of criteria, starting at a given root."
- >DirectoryScannerMXBean</a></code> and points
- towards a <code><a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ScanDirConfigMXBean.html"
-title="The ScanDirConfigMXBean is in charge of the configuration"
- >ScanDirConfigMXBean</a></code>.
- </li>
- </ul>
- <p>In short, MXBeans are so much easier to use that
- this example doesn't even have a single regular
- Standard MBean.

- <blockquote><u>Hint:</u> In order to simplify the task of coding a
- JMX programmatic client, we recommend that getters, setters, and
- operations defined in MBean and MXBean interfaces throw
- <code>IOException</code>. Proxy objects will then be able
- to rethrow directly any <code>IOException</code> received from
- their underlying MBean Server connection, without wrapping
- them into <code>UndeclaredThrowableExceptions</code>.<br>
- Since the life cycle of the proxy object is not directly tied to
- the life cycle of the MBean it proxies, you may also want to
- have all methods in the MBean or MXBean interface throw
- <code>InstanceNotFoundException</code> or more generally
- <code>JMException</code>.
- </blockquote>
- </ul>
- <h3>MBean Names - aka ObjectNames</h3>
- <ul>
- <p>As you must know if you've been studying JMX, MBeans are
- named objects. The names of MBeans are represented by
- instances of <code>ObjectName</code>. An ObjectName is
- composed of a <i>domain</i>, followed by a colon ':',
- followed by a comma-separated list of <i>key=value</i>
- pairs.<br>
- The ordering of the <i>key=value</i> pairs is not
- important, but <code>ObjectNames</code> are case sensitive
- (both keys and values are case sensitive) and <b>white space
- is not ignored</b>.<br>
- A common pitfall for JMX beginners is to inadvertently
- insert white space after commas into an ObjectName,
- and expect that two ObjectNames which differ only by such white
- space will be considered identical. This is not the
- case.<br>
- As an example, the ObjectName '<b><code>D:k1=v1, k2=v2, k3=v3</code></b>' has
- three keys, which are '<b><code>k1</code></b>', '<b><code> k2</code></b>',
- and '<b><code> k3</code></b>': beware
- of the space in the name of the second and third
- keys!<br>
- It is therefore a different ObjectName from
- '<b><code>D:k1=v1,k2=v2,k3=v3</code></b>' (the keys are now
- '<b><code>k1</code></b>', '<b><code>k2</code></b>', and
- '<b><code>k3</code></b>'), but the same ObjectName as
- '<b><code>D: k2=v2, k3=v3,k1=v1</code></b>', and yet different
- from '<b><code>D:k2=v2, k3=v3, k1=v1</code></b>'!
- <p>In this example, we are following the rules
- for ObjectName suggested in the <a
-href="http://java.sun.com/products/JavaManagement/best-practices.html"
- >JMX Best Practices</a>:</p>
- <ul>
- <li>ObjectNames should be <a
- href="http://java.sun.com/products/JavaManagement/best-practices.html#mozTocId654884"
- >predictable</a>
- </li>
- <li>The domain part of our ObjectNames starts with a Java
- package name
- </li>
- <li>Our ObjectNames contain a <code>type=</code>
- key property. This property is different for every
- object type in our domain.
- </li>
- <li>For every ObjectName with a given type, we have the same set of key
- properties with the same syntax and semantics for their values - in
- fact we only use an additional <code>name=</code> key.
- </li>
- <li>When there can only be one instance of a given type
- there aren't any other key properties than <code>type=</code>.
- The ObjectNames of the <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ScanManagerMXBean.html"
-title="The ScanManagerMXBean is the main MBean of the scandir application"
- >ScanManagerMXBean</a> and <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ResultLogManagerMXBean.html"
-title="The ResultLogManagerMXBean is in charge of managing result logs"
- >ResultLogManagerMXBean</a>, which are both singleton MBeans, are
- composed in this way.
- </li>
- <li>When there can be several instances of a given type,
- we differentiate them by further key properties.
- To achieve this, we are using the most usual key property
- in addition to <code>type=</code>: the <code>name=</code> key.
- In this example, a key property list of the form
- <code>type=X,name=Y</code> is always enough to uniquely name
- an MBean. Tools like jconsole are usually aware
- of the semantics of the <code>type=</code> key and
- <code>name=</code> key, and are therefore able to
- display this form of name in a way that
- is easier to read than other name forms.
- </li>
- </ul>
- <p>The rules listed above are implemented by a couple
- of static helper functions in the <a
-href="src/com/sun/jmx/examples/scandir/ScanManager.java"
-title="ScanManager.java"
- >ScanManager</a> class. See the code of the
- <b><code>makeSingletonName</code></b> and
- <b><code>makeMBeanName</code></b> methods.
- </p>
- </ul>
- <h3>Inter MBean Navigation</h3>
- <ul>
- <p>One of the most common problems that needs to be solved
- when designing a management interface with JMX is to
- choose a representation for inter-MBean relationships.<br>
- Prior to Java 6, there were basically three possible
- choices:</p>
- <ul>
- <li><b>Make the relation appear in the ObjectName</b>.
- For instance, if MBean B was contained in
- MBean A, you could choose to name MBean B so
- that its parent relationship with MBean A
- appeared in its name. <br>
- The obvious limitation of this solution is that
- it only allows to model one such relation (an
- MBean has only one name) and the relation must
- be fixed - it cannot change during the life of
- the MBean since the name of an MBean cannot
- change.<br>
- This scheme is therefore mostly used when
- the application MBeans are modeling objects
- which are conceptually contained within
- each other in a tree-like structure.
- <br>For instance, most MBean names defined by
- <a href="http://jcp.org/en/jsr/detail?id=77"
- >J2EE Management (JSR 77)</a> follow
- this scheme.
- </li>
- <li><b>Design getters and setters (or operations) which
- return <code>ObjectName</code> or
- <code>ObjectName[]</code> values</b>. The ObjectNames
- point to the MBeans which are related to that
- object. For instance , <a
- href="http://glassfish.dev.java.net/"
- title="Open Source Java EE 5 Application Server"
- >GlassFish</a>
- defines MBeans which also use this pattern.
- </li>
- <li><b>Use the JMX RelationService</b>. The JMX RelationService
- is quite powerful, but simple relationships often
- do not justify that overhead.
- </li>
- </ul>
- <p>In Java 6, these three possibilities still remain, but
- the new MXBean framework brings up an interesting
- alternative. Instead of returning an ObjectName or
- an ObjectName array, <b>an MXBean can return a proxy</b>
- to its related MXBeans. This is how we have chosen to
- implement our inter MBean relationships in this
- example:
- <br>For instance the
- <code>ScanManagerMXBean</code>/<code>DirectoryScannerMXBean</code>
- relationship and the
- <code>ScanManagerMXBean</code>/<code>ScanDirConfigMXBean</code>
- relationships are implemented in this way.
- <p>
- The additional benefit, as compared to returning ObjectNames or
- using the RelationService is that interface type of the MBeans
- which are pointed to by the relationship becomes directly
- apparent. The method:
- <pre>
- public Map<String,DirectoryScannerMXBean> getDirectoryScanners();
- </pre>
- makes it immediately obvious that the MBeans to which we point are
- <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/DirectoryScannerMXBean.html"
-title="A DirectoryScannerMXBean looks for file matching a given set of criteria, starting at a given root."
- >DirectoryScannerMXBeans</a>. It would have been much less obvious in prior
- versions of Java SE, were the returned type would have had to be
- <code>Map<String,ObjectName></code>, or
- even worse just <code>Map</code>.
- </p>
- <p>However, it must be clear that the behaviour will be
- quite different when an MXBean is returned as compared
- to when a simple bean is returned.
- </p>
- <p>When an MXBean is returned, the remote client sees either
- an ObjectName, if it is a generic client like jconsole, or
- a proxy to a remote MXBean, if the client is working with the
- MXBean interface. Invoking an operation on one of the
- proxy returned by a method such as
- <code>getDirectoryScanners</code> will cause the
- MBean to be invoked on the remote server side.
- </p>
- <p>If <code>getDirectoryScanners</code> were
- defined as:
- <pre>
- public Map<String,DirectoryScannerConfig> getDirectoryScanners();
- </pre>
- then invoking a method on one of the returned objects
- would have absolutely no effect on the remote
- server side - because the returned objects in this
- case would simply be a bunch of serialized data objects.
- </p>
- <p>It is worth noting that although an MXBean interface
- can have getters and operations which return an MXBean
- interface, a regular standard MBean shouldn't have
- any getters or methods which return MBean interfaces or
- MXBean interfaces.

- </p>
- </ul>
- <h3>The MBeanRegistration interface, or how an MBean can
- know or provide its own name</h3>
- <ul>
- <p>
- Sometimes, an MBean needs to have a reference to the
- MBeanServer in which it is registered, or needs to know
- with which ObjectName it has been registered.
- </p>
- <p>
- Sometimes also, an MBean may need to perform some
- checks before being registered, or will need
- to carry out some actions right after it has been
- successfully registered in the MBeanServer.
- </p>
- <p>
- Sometimes again, an MBean may need to perform some
- checks, or some cleaning actions, just before, or
- just after, it is unregistered.
- </p>
- <p>
- When an MBean has such needs, the easiest solution
- for it is to implement the <code>MBeanRegistration</code>
- interface.
- </p>
- <p>The <code>MBeanRegistration</code> interface is a callback
- interface which defines pre and post registration and
- unregistration callbacks.
- </p>
- <p>
- When an MBean implementing this interface is created
- (with <code>createMBean</code>) or registered
- (with <code>registerMBean</code>) in an MBeanServer,
- the MBeanServer will call the <code>preRegister</code>
- and <code>postRegister</code> method implemented by
- the MBean. The <code>preRegister</code> method
- has an <code>MBeanServer</code> and <code>ObjectName</code>
- parameter, which are passed by the MBeanServer to the
- MBean. The MBean can store the reference it is being passed
- in a private instance variable for later use.
- </p>
- <p>
- Most of the MXBeans we have defined in this example
- implement the <code>MBeanRegistration</code> interface. The table
- below show how our MBeans use this interface to control
- their own names, make sanity checks, perform
- initialization steps or cleanup actions.

- <h3>The Singleton MBean Pattern</h3>
- <ul>
- <p>
- A singleton MBean is an MBean which can only have one
- instance registered in a given MBeanServer. <br>
- A singleton MBean usually has a well-known name,
- which can be defined as a constant. In that case,
- clients no longer need to call <code>new ObjectName(...)</code>
- and catch the declared <code>MalformedObjectNameException</code>.
- </p>
- <p>There are already quite a few examples of singleton
- MBeans in the java.lang.management API. The
- ThreadingMXBean, ClassLoadingMXBean, RuntimeMXBean, etc.
- are all singleton MBeans.
- </p>
- <p>In this example, we have two singleton MBeans:
- The <code><a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ScanManagerMXBean.html"
-title="The ScanManagerMXBean is the main MBean of the scandir application"
- >ScanManagerMXBean</a></code> and the
- <code><a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ResultLogManagerMXBean.html"
-title="The ResultLogManagerMXBean is in charge of managing result logs"
- >ResultLogManagerMXBean</a></code>. But in fact,
- the only real singleton MBean is the
- <code>ScanManagerMXBean</code>. The
- <code>ResultLogManagerMXBean</code> just happens to
- be a singleton MBean because it has a 1-1 relationship
- with the <code>ScanManagerMXBean</code>.
- </p>
- <p>The <code>ScanManagerMXBean</code> implements the
- singleton MBean pattern in this way:
- </p>
- <ul>
- <li>The <code>ScanManagerMXBean</code> name has a single
- key property: <code>type=ScanManagerMXBean</code>.</li>
- <li>Its name is defined by an ObjectName constant called
- <code>SCAN_MANAGER_NAME</code> in the <code>ScanManager</code> class</li>
- <li>The <code>ScanManagerMXBean</code> enforces its status of
- singleton MBean. It will refuse to be registered
- with a name other than
- the <code>SCAN_MANAGER_NAME</code>. You can therefore depend on
- the fact that the <code>ScanManagerMXBean</code> will always
- be registered with its singleton <code>SCAN_MANAGER_NAME</code>
- (see <code>preRegister</code>)
- </li>
- <li>You are not obliged to provide a name when you
- register the <code>ScanManagerMXBean</code>: if you pass null,
- then the <code>ScanManager</code> will be registered with
- its singleton <code>SCAN_MANAGER_NAME</code>
- (see <code>preRegister</code>).
- </li>
- <li>The <code>ScanManager</code> class has a no-arg static
- <code>register</code> method that will register
- the singleton instance in the Platform MBeanServer.
- This static <code>register</code> method returns
- a proxy to the registered singleton.
- </li>
- <li>The <code>ScanManager</code> class has also a static
- <code>register</code> method that will create
- a singleton instance in a (possibly remote)
- MBeanServerConnection - using
- <code>createMBean</code>.
- This static <code>register</code> method
- also returns a proxy to the registered singleton.
- </li>
- <li>Only the MBeanServer has a reference to the
- singleton instance. The singleton instance is
- not returned to the caller, and not kept
- in any other static data structure.
- </li>
- </ul>
- <p>
- On the other hand, the <code><a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ResultLogManagerMXBean.html"
-title="The ResultLogManagerMXBean is in charge of managing result logs"
- >ResultLogManagerMXBean</a></code>
- has a much more relaxed implementation of the pattern:
- <br>It simply provides its own singleton name if it is
- registered with a null ObjectName, but will not enforce
- the use of that name.
- </p>
- <p>Note that all singleton MBean names in this example
- are created using the <code>ScanManager.makeSingletonName</code>
- method, which implements the pattern for ObjectNames suggested
- in the JMX Best Practices.
- </p>
- </ul>
- <h3>Managing the Life Cycle of dependent MBeans</h3>
- <ul>
- <p>A common task that many JMX applications have
- is to manage the life cycle of MBeans registered
- in the MBeanServer.</p>
- <p>In this example, we have decided to follow a simple
- pattern:</p>
- <ul>
- <li>The application is initialized simply
- by registering the singleton
- <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ScanManagerMXBean.html"
-title="The ScanManagerMXBean is the main MBean of the scandir application"
- >ScanManagerMXBean</a> in
- the MBeanServer.
- </li>
- <li>The <code>ScanManagerMXBean</code> will then
- in turn register any other MBean that the
- application might need:
- <ul>
- <li>It creates and registers the singleton
- <code><a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ResultLogManagerMXBean.html"
-title="The ResultLogManagerMXBean is in charge of managing result logs"
- >ResultLogManagerMXBean</a></code>
- </li>
- <li>It creates and registers the default
- <code><a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ScanDirConfigMXBean.html"
-title="The ScanDirConfigMXBean is in charge of the configuration"
- >ScanDirConfigMXBean</a></code>
- which loads the initial configuration
- </li>
- <li>It creates as many
- <code><a
-href="dist/javadoc/com/sun/jmx/examples/scandir/DirectoryScannerMXBean.html"
-title="A DirectoryScannerMXBean looks for file matching a given set of criteria, starting at a given root."
- >DirectoryScannerMXBeans</a></code> as
- needed when the configuration is applied
- </li>
- <li>It lets you create alternate
- <code>ScanDirConfigMXBean</code>, to
- which you can later switch in order
- to apply a new alternate configuration.
- </li>
- </ul>
- </li>
- <li>When a new configuration is applied (or if the
- current configuration is reapplied), the
- <code>ScanManagerMXBean</code> will unregister
- any <code>DirectoryScannerMXBeans</code> it has
- previously registered, and will re-create
- brand new <code>DirectoryScannerMXBeans</code>
- from the applied configuration.
- </li>
- <li>When you unregister the <code>ScanManagerMXBean</code>,
- it does all the cleanup for you, by unregistering
- all the MBeans that it has created during the
- course of the application.
- </li>
- </ul>
- <p>The <code>ScanManagerMXBean</code> makes use of its
- <code>MBeanRegistration</code> interface in order
- to register the other MBeans it needs (see the
- <code>ScanManager.postRegister</code> method) and to unregister
- every MBean it has created (see the <code>ScanManager.preDeregister</code>
- method).
- </p>
- <p>You will note that the <code>ScanManagerMXBean</code>
- will only allow itself to be deregistered if it can be
- closed - that is if there's no other action in
- progress.
- This is to make sure that the deregistration of
- dependent MBeans will work smoothly.
- <br>
- The deregistration of related MBeans will happen
- in the <code>ScanManager.preDeregister</code>
- method.
- <br>
- If one of these MBeans could not be deregistered,
- then the <code>ScanManagerMXBean</code> will throw
- an exception, refusing to be deregistered.
- <br>This leaves you a chance to try to deregister it
- again later. Since the <code>ScanManagerMXBean</code>
- has switched its state to CLOSED before starting
- to unregister its dependent MBeans, it will refuse
- any further actions, ensuring that e.g. nobody
- can try to start it or schedule it while it
- is in that partially-deregistered state.
- </p>
- <p>Handling the LifeCycle of all the application's
- MBeans in a single MBean is usually a good design
- pattern, especially if the application is a
- module which is intended to share a JVM - or
- an MBeanServer - with other modules.
- </p>
- <p>This is specially useful if the application needs to
- be loaded and unloaded on demand: in that
- case, simply registering or unregistering the top level
- MBean (in our example the <code>ScanManagerMXBean</code>) does
- the trick.
- </p>
- </ul>
- <h3>Emitting Notifications</h3>
- <ul>
- <p>In order to emit notifications, an MBean must be
- an instance of <code>NotificationEmitter</code>.
- The <code>NotificationEmitter</code> interface defines methods
- that the MBeanServer will call on the MBean in order
- to register <code>NotificationListeners</code> with the MBean.
- </p>
- <p>It is worth noting that the MBean may not be
- invoked each time a JMX client wants to register
- a listener. For instance, the RMIConnectorServer
- registers <i>only once</i> a single listener with each MBean
- which is a <code>NotificationEmitter</code>.
- In that specific case, the listener may even be registered
- with the MBean before any client has actually subscribed
- for notifications from that particular MBean.
- </p>
- <p>An MBean can therefore make no assumption about
- which client or how many clients have registered for
- notifications.
- </p>
- <p>It is also worth noting that the logic of the
- methods defined in <code>NotificationEmitter</code> would not
- be trivial to implement from scratch. Fortunately
- the JMX API defines a helper class, called
- <code>NotificationBroadcasterSupport</code>, which
- provides an implementation for these methods.
- </p>
- <p>There are actually three ways for an MBean to
- implement <code>NotificationEmitter</code>, of which only two
- are recommended.
- </p>
- </ul>
-
- <h4>Extending NotificationBroadcasterSupport</h4>
- <ul>
- <p>This is the simplest way of coding an MBean which
- is a <code>NotificationEmitter</code>:
- </p>
- <p>Simply extend <code>NotificationBroadcasterSupport</code>,
- then override its <code>getNotificationInfo</code> method
- which returns the <code>MBeanNotificationInfo[]</code> array
- that should be included in your MBean's <code>MBeanInfo</code>
- and that's it.
- <br>You just need to call the <code>sendNotification</code> method
- inherited from <code>NotificationBroadcasterSupport</code> whenever
- your MBean needs to send a notification.
- </p>
- <p>In our example, both the <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ScanDirConfigMXBean.html"
-title="The ScanDirConfigMXBean is in charge of the configuration"
- >ScanDirConfigMXBean</a> and <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ResultLogManagerMXBean.html"
-title="The ResultLogManagerMXBean is in charge of managing result logs"
- >ResultLogManagerMXBean</a> extend
- <code>NotificationBroadcasterSupport</code> in order
- to send notifications.
- </p>
- </ul>
- <h4>The Delegation Pattern: delegating to a
- NotificationBroadcasterSupport delegate</h4>
- <ul>
- <p>There may be cases however where delegating to a
- wrapped <code>NotificationBroadcasterSupport</code>
- object may be preferred to extending
- <code>NotificationBroadcasterSupport</code>.
- </p>
- <p>For instance, if your MBeans already derive from
- some base class, extending <code>NotificationBroadcasterSupport</code>
- might not be an option.
- </p>
- <p>Similarly, if you do not want to have the inherited
- <code>public void sendNotification(Notification notification)</code>
- method appear in the Javadoc of the concrete class of your
- MBean, you may want to consider using the delegation
- pattern instead of extending
- <code>NotificationBroadcasterSupport</code>
- </p>
- <p>In our example both the <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ScanManagerMXBean.html"
-title="The ScanManagerMXBean is the main MBean of the scandir application"
- >ScanManagerMXBean</a> and the <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/DirectoryScannerMXBean.html"
-title="A DirectoryScannerMXBean looks for file matching a given set of criteria, starting at a given root."
- >DirectoryScannerMXBean</a> use the delegation
- pattern rather than extending
- <code>NotificationBroadcasterSupport</code>.
- In the end, choosing between one or the other method
- is more a question of taste, although the delegation
- pattern could be considered more flexible since it
- doesn't require extending any given superclass.
- </p>
- <p>It may be also worth noting that some tools like
- the JMX Module of <a
-href="http://www.netbeans.org"
- >NetBeans IDE</a>, will be able to
- generate for you all the code that delegates to a
- wrapped <code>NotificationBroadcasterSupport</code>.
- </p>
- </ul>
-
- <h4>Implementing NotificationEmitter from scratch</h4>
- <ul>
- <p>This is the last possibility for an MBean that
- needs to send notifications: simply implement
- <code>NotificationEmitter</code> from scratch. This is highly
- discouraged since that logic is not trivial, and
- already provided by
- <code>NotificationBroadcasterSupport</code> anyway.
- </p>
- </ul>
-
- <h4>Beware of Synchronization Locks</h4>
- <ul>
-
- <p>One thing you must keep in mind when sending
- notifications is not to send them from within
- a synchronized block, or while holding a lock on
- some resource.</p>
- <p>Indeed, what happens when you send a notification
- may vary greatly depending on whether the client
- which has registered for notifications has done
- so through a <code>JMXConnector</code> (like the
- <code>JMXRMIConnector</code>)
- or through a direct reference to the MBeanServer
- (by calling
- <code>MBeanServer.addNotificationListener</code>).
- </p>
- <p>In this latter case, the listener will be invoked
- synchronously in the same thread that your MBean is
- using to send its notification. If by misfortune, the
- code of that listener now re-enters your MBean through a
- call that flows through a JMXConnector, a deadlock
- could occur. It is therefore very important to release
- any lock you may have before calling
- <code>sendNotification</code>.</p>
- <p>An easy way to do that is demonstrated in the
- <code>ScanManager</code> class. The ScanManager
- has an internal private queue of pending notifications.
- When a notification needs to be sent (e.g. because the
- ScanManager state is being switched), the notification
- is simply prepared and put into the pending notification
- queue.
- The notification queue is then processed later on,
- at the end of the method, when the processing is finally
- completed and all the locks have been released.
- <br>At this point the notification queue might already
- have been emptied by another thread - in which case
- the pending notifications will have already been
- removed from the queue. Which thread actually gets
- to send the notifications is of no importance. The
- important point is that all the locks detained by
- your MBean code in that thread were released before
- the notification was sent.
- </p>
- <p>In our example the <code>ScanManager</code> class
- ensures this by:
- <ul>
- <li>Only calling <code>sendNotification</code>
- in its private <code>sendQueuedNotifications</code>
- method.
- </li>
- <li>Only calling <code>sendQueuedNotifications</code>
- when all locks have been released.
- </li>
- <li>Never calling a method that calls
- <code>sendQueuedNotifications</code> from within
- a synchronized block.</li>
- </ul>
- </p>
- </ul>
-
-
-
- <h4>Don't subclass Notification</h4>
- <ul>
- <p>Another common best practice when you want
- to improve interoperability is to use directly
- the Notification base classes provided in the
- JMX™ API. Do not create your own
- subclasses of these standard classes.
- </p>
- <p>Indeed, if you code your own subclass, a generic
- client, like jconsole, will not be able to receive
- that notification unless it has that custom
- subclass in its classpath.
- </p>
- <p>
- If you want your application to be interoperable, it is
- therefore preferable not to subclass any of the standard
- Notification classes. You can define your own
- Notification type string, and if you need to send
- additional data, you can put a CompositeData, or a
- HashMap of serializable standard types in the
- Notification's user data fields.
- </p>
- <p>In this example, we are using directly the
- standard notification classes:
- <ul>
- <li>The <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ScanManagerMXBean.html"
-title="The ScanManagerMXBean is the main MBean of the scandir application"
- >ScanManagerMXBean</a> and the <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/DirectoryScannerMXBean.html"
-title="A DirectoryScannerMXBean looks for file matching a given set of criteria, starting at a given root."
- >DirectoryScannerMXBean</a> both use directly
- <code>AttributeChangeNotification</code> to notify
- changes in their <code>State</code> attribute.
- </li>
- <li>The <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/DirectoryScannerMXBean.html"
-title="A DirectoryScannerMXBean looks for file matching a given set of criteria, starting at a given root."
- >DirectoryScannerMXBean</a>
- also uses the base <code>Notification</code>
- class directly in order to notify whenever
- it finds a matching file.
- <br>In that case, we simply use the base
- <code>Notification</code>
- class with a new
- <b><code>com.sun.jmx.examples.scandir.filematch</code></b>
- type.
- </li>
- <li>The <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ScanDirConfigMXBean.html"
-title="The ScanDirConfigMXBean is in charge of the configuration"
- >ScanDirConfigMXBean</a> and <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ResultLogManagerMXBean.html"
-title="The ResultLogManagerMXBean is in charge of managing result logs"
- >ResultLogManagerMXBean</a> also both use the base
- <code>Notification</code> class.
- </li>
- </ul>
- <p>Careful readers will have noted that the <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ScanManagerMXBean.html"
-title="The ScanManagerMXBean is the main MBean of the scandir application"
- >ScanManagerMXBean</a> and the <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/DirectoryScannerMXBean.html"
-title="A DirectoryScannerMXBean looks for file matching a given set of criteria, starting at a given root."
- >DirectoryScannerMXBean</a> both use the
- <code>AttributeChangeNotification</code> class
- to notify about their state change, whereas the
- <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ScanDirConfigMXBean.html"
-title="The ScanDirConfigMXBean is in charge of the configuration"
- >ScanDirConfigMXBean</a> uses the base
- <code>Notification</code> class.
- </p>
- <p>In fact, this is because the semantics of these
- notifications is not exactly the same - although
- both denote a state change:
- <ul>
- <p>In the case of <code>ScanManagerMXBean</code>
- and <code>DirectoryScannerMXBean</code>, the
- notification which is emitted is more about a
- state transition, from one state to another.
- For instance, going from <code>RUNNING</code>
- to <code>STOPPED</code>, or from
- <code>SCHEDULED</code> to <code>STOPPED</code>.
- <br>In that case, the
- <code>AttributeChangeNotification</code> was
- more appropriate because it made it possible
- to send the previous and the new value of the
- state attribute, thus reflecting the whole
- state transition.
- </p>
- <p>In the case of the <code>ScanDirConfigMXBean</code>
- however, what is of interest is the state in
- which the MBean has arrived. Using the base
- <code>Notification</code> class with three different
- notification type strings -
- <b><code>com.sun.jmx.examples.scandir.config.loaded</code></b>,
- <b><code>com.sun.jmx.examples.scandir.config.modified</code></b>,
- and
- <b><code>com.sun.jmx.examples.scandir.config.saved</code></b> -
- was therefore closer to what we wanted to model.
- </p>
- </ul>
- </p>
- </ul>
-
- <h3>Configuration MBeans</h3>
- <ul>
- <p>A common practice when designing a management application is
- to have an MBean, or a set of MBeans, dedicated to configuration.
- Separating configuration from control and monitoring allows
- more appropriate logic, and often simplifies the design and
- implementation of the management interface.
- </p>
- <p>
- In our example, the <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ScanDirConfigMXBean.html"
-title="The ScanDirConfigMXBean is in charge of the configuration"
- >ScanDirConfigMXBean</a> is dedicated to the application configuration.
- </p>
- <p>The <code>ScanDirConfigMXBean</code> will let you interactively
- modify, save, or load the application configuration. The modifications
- will not be taken into account until it is applied, by invoking
- <code>applyConfiguration</code> on the <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ScanManagerMXBean.html"
-title="The ScanManagerMXBean is the main MBean of the scandir application"
- >ScanManagerMXBean</a>.
- It is also possible to create many configurations, by creating as
- many <code>ScanDirConfigMXBean</code>s, and then to choose and apply
- one of these configurations by calling
- <code>ScanManagerMXBean.setConfigurationMBean</code> and then
- <code>ScanManagerMXBean.applyConfiguration</code>.
- </p>
- <p>In this way, all configurations aspects are gathered and concentrated
- inside the <code>ScanDirConfigMXBean</code> instead of being scattered
- throughout all the MBeans that compose the application.
- </p>
- <p>In order to save and store the application configuration data, the
- <code>ScanDirConfigMXBean</code> uses a set of XML serializable Java beans
- defined in the <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/config/package-summary.html"
-title="The com.sun.jmx.examples.scandir.config package defines XML serializable beans"
- >com.sun.jmx.examples.scandir.config</a> package. These beans are very
- simple Java beans which have been lightly annotated for XML binding.
- </p>
- <p>It is worth noting that these same beans can also be handled by the
- MXBean framework (our beans don't contain recursive data structures) and can
- therefore be used directly as attributes and parameters of MXBeans, without
- needing to be Java-serializable (the MXBean framework transform them in
- CompositeData objects - which <b>are</b> serializable).
- </p>
- <p>The same <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/config/ScanManagerConfig.html"
-title="The com.sun.jmx.examples.scandir.config package defines XML serializable beans"
- >ScanManagerConfig</a> bean that we use to read from and write to the
- XML configuration file is thus also used as attribute of the <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ScanDirConfigMXBean.html"
-title="The ScanDirConfigMXBean is in charge of the configuration"
- >ScanDirConfigMXBean</a>. It is transformed into a <code>CompositeData</code>
- by the MXBean framework, and can be easily introspected with
- <a href="#JConsole">jconsole</a>.
- </p>
- </ul>
- <h3>MBeans Must Be Thread-Safe</h3>
- <ul>
- <p>A question often asked by newcomers to JMX technology
- is whether the MBeanServer is thread-safe. Well, the MBeanServer <b>is</b>
- thread safe, but it doesn't put any locks on the MBeans it contains. The
- MBeans can be concurrently accessed by multiple threads, and must therefore
- take care of their own thread safety.
- </p>
- <p>In this example, we have been using two methods to ensure thread
- safety for our MBeans: synchronized blocks, and semaphores.
- </p>
- <p>Using synchronized blocks is probably the most common and easiest way
- to implement thread safety in Java. When dealing with MBeans though, here
- are a couple of rules to keep in mind:
- <ul>
- <li>Don't send notifications from within a synchronized block: there's
- no way to tell whether the listener's code will be executed in the
- same thread or a different thread, and holding a lock in these
- conditions is therefore dangerous, as it could lead to deadlocks.</li>
- <li>Also avoid invoking another MBean from a synchronized block
- unless you are completely in control of both MBeans, and you can
- ascertain that it won't lead to any deadlock. Indeed, if you invoke an
- MBean exposed by another application, it can be sometime hard to
- know with certainty whether holding a lock while invoking that
- MBean will have any side effect. Maybe that MBean will make
- further calls to other MBeans which will in turn try to call
- your MBean, or maybe it will emit a
- notification, and we'll be back to the considerations just
- above.</li>
- </ul>
- </p>
- <p>Another means of implementing thread-safe code is to use semaphores.
- The <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ScanManagerMXBean.html"
-title="The ScanManagerMXBean is the main MBean of the scandir application"
- >ScanManagerMXBean</a> uses a semaphore called
- <code>sequencer</code> to ensure
- that critical code sections are not executed concurrently. In this
- MBean, we use <code>Semaphore.tryAcquire</code> to lock the sequencer
- semaphore before entering the critical section. If the
- <code>Semaphore.tryAcquire</code> returns true then we enter the critical
- section. If it returns false, we throw an IllegalStateException, stating
- that we couldn't acquire the lock. The code looks like this:
- <pre>
- if (!sequencer.tryAcquire())
- throw new IllegalStateException("resource locked");
- try {
- // critical code here ...
- } finally {
- // Always use try/finally to ensure that the semaphore
- // will be released, even if exceptions or errors are raised!
- sequencer.release();
- }
- </pre>
- </p>
- <p>Using <code>Semaphore.tryAcquire</code> and throwing an exception if
- the semaphore is already locked makes it safer to call other MBeans
- from within the critical section: in potential deadlock situations
- the calling code will get the <code>IllegalStateException</code>
- instead of being blocked on the deadlocked lock.
- </p>
- <p>It is worth noting that each of these techniques has its own
- advantages and disadvantages - which can make one of them more or less
- appropriate depending on the inner logic of the MBean you're implementing.
- </p>
- <p>Careful readers will also have noted that we used
- <code>IllegalStateException</code> directly, instead of defining
- our own subclass of RuntimeException, which could have had a more
- precise semantics. If you define a new exception for your JMX application,
- you must keep in mind that your client will need to have the class
- of your exception in its classpath to get that exception.
- Otherwise your client will get a completely different exception, indicating a
- deserialization issue.
- </p>
- </ul>
-
- <h3>Waiting for Notifications</h3>
- <ul>
- <p>Implementing code that needs to wait for notifications is sometimes
- difficult. Because notifications are asynchronous, doing something
- like:
- <pre>
- // register a notification listener
- ...
- // start a management action
- ...
- // wait for a notification
- ...
- // do something based on whether the expected notification
- // is received
- ...
- </pre>
- is not always trivial. However, there's a very easy way to do that: use
- a blocking queue of notifications.
- <pre>
- final BlockingQueue<Notification> notifQueue =
- new LinkedBlockingQueue<Notification>();
-
- final NotificationListener listener = new NotificationListener() {
- public void handleNotification(Notification notification,
- Object handback) {
- try {
- // Just put the received notification in the queue.
- // It will be consumed later on.
- //
- notifQueue.put(notification);
- } catch (InterruptedException ex) {
- // OK
- }
- }
- };
-
- // register the listener - possibly also as a JMXConnectionNotification
- // listener to get Notification Lost notification
- ...
- // start management action
- ...
- // wait for notification
- while (expected notif not received and delay not expired) {
- Notification n = notifQueue.poll(3,TimeUnit.SECONDS);
- // if expected notif, do something
- ...
- }
- // if expected notification not received do something else.
- ....
- </pre>
- </p>
- <p>You will note that this is a technique we've been using in the <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ScanDirAgent.html"
-title="The ScanDirAgent class defines a main method for the scandir application"
- >ScanDirAgent</a> class and in the example unit tests.
- </p>
- </ul>
-
- <h3>Holding hard references to other MBeans: proxy or direct reference?</h3>
- <ul>
- <p>We have seen that MXBeans will let you return proxy references to other
- MXBeans. But should that MXBean hold a direct reference to the MXBeans it
- relates to, or would it be better for it to hold only a proxy?
- </p>
- <p>
- As a general rule it is better when an MBean reference is
- only held by the MBeanServer. It is a better design
- to hold a reference to a proxy, rather than to hold
- a hard reference to an MBean. However there are two cases
- when holding a hard reference might be preferred:
- <ol>
- <li>When MBean A needs to call a method of method B which
- is not part of its MBean interface</li>
- <li>When the overhead of going through the MBeanServer
- plus the MXBean framework is too great (frequently-called
- method, with creation of OpenType)</li>
- </ol>
- However - holding a hard reference is only advisable
- when both MBeans are created by the same piece of code,
- and the application can ensure that the life cycle
- of each MBean is consistent with regard to the other.
- </p>
- <p>In our example, the <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ScanManagerMXBean.html"
-title="The ScanManagerMXBean is the main MBean of the scandir application"
- >ScanManagerMXBean</a> holds only proxy references to the <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ScanDirConfigMXBean.html"
- >ScanDirConfigMXBean</a> and the <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/DirectoryScannerMXBean.html"
- >DirectoryScannerMXBeans</a>. <br>
- However it holds a direct reference to the <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ResultLogManager.html"
- >ResultLogManager</a>. This makes it possible to pass a direct
- reference to the <code>DirectoryScannerMXBeans</code>,
- which can then log their results
- more efficiently, and would also make it possible to remove
- the <code>log</code> method from the <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ResultLogManagerMXBean.html"
- >ResultLogManagerMXBean</a> interface - leaving it in the
- <code>ResultLogManager</code> class (possibly as a package method)
- should we wish to do so.
- </p>
-
- </ul>
-
- <h3>Agent Class</h3>
- <ul>
- <p>The <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ScanDirAgent.html"
-title="The ScanDirAgent class defines a main method for the scandir application"
- >ScanDirAgent</a> is the Agent class for the <i>scandir</i> application.
- This class contains the <code>main</code> method to start a standalone
- <i>scandir</i> application.
- </p>
- <p>The <code>main</code> method simply registers a <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ScanManagerMXBean.html"
-title="The ScanManagerMXBean is the main MBean of the scandir application"
- >ScanManagerMXBean</a> in the platform MBeanServer, and then waits
- for someone to call <code>ScanManagerMXBean.close</code>.
- </p>
- <p>
- When the <code>ScanManagerMXBean</code> state is switched to
- <code>ScanManagerMXBean.ScanState.CLOSED</code>, the
- <code>ScanManagerMXBean</code> is unregistered, and the application
- terminates (i.e. the main thread completes).
- </p>
- <p>Standalone JMX applications usually have an Agent class that contain
- their <code>main</code> method, which performs all the MBean
- registration steps.
- However, it is usually not a bad idea if that class can
- be easily turned into an MBean. Indeed, this will make your
- application easier to integrate in an environment where it would
- no longer be standalone and would no longer control the implementation
- of <code>main</code>. In our example the Agent
- class could be easily turned into an MBean, exposing its three
- <code>init</code>, <code>waitForClose</code> and <code>cleanup</code>
- method. However we didn't go as far as turning it into an MBean since
- the application can be already easily started by registering an instance
- of <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ScanManagerMXBean.html"
-title="The ScanManagerMXBean is the main MBean of the scandir application"
- >ScanManagerMXBean</a>.
- </p>
- </ul>
- <h3>Secure Client Class</h3>
- <ul>
- <p>The <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ScanDirClient.html"
-title="The ScanDirClient class is a very short example of secure programmatic client"
- >ScanDirClient</a> is an example class that shows how a
- programmatic client can connect to a secured <i>scandir</i> application.
- This class contains a <code>main</code> method which creates and
- configures a <code>JMXConnector</code> client to connect with
- a secured <i>scandir</i> daemon. This class will not work with
- the default unsecured agent since it requires mutual authentication.
- </p>
- <p>How to secure a JMX <i>scandir</i> application and run
- the secure <code>ScanDirClient</code> is discussed <a href="#secure"
- >later</a> in this document.
- </p>
- <p>The <code>ScanDirClient</code> is not really part of the

- <h2><a name="h2-Turning">Turning the example into a Secure JMX Application</a></h2>
- <ul>
- <p>In this section, we will see how to configure and
- start the <i>scandir</i> example so that the JVM agent
- is bootstrapped with a secure JMXConnectorServer. Indeed, until
- now we have only used the insecure local connection,
- which can only be used as long as both the client and
- the server run on the same machine. This section will
- explain how to start the <code>ScanDirAgent</code> so
- that a real secure RMIConnectorServer is started at bootstrap.
- </p>
- <p>To achieve this we will: <a href="#management.properties"
- >provide our own management.properties</a>, <a
- href="#password-access">create our own password and access files</a>,
- <a href="#keystore-truststore">provide a keystore and truststore</a>,
- <a href="#start-secure-agent">start the ScanDirAgent with the
- appropriate system properties</a>.
- </ul>
- <h3>Configuring the JVM Agent for Secure Remote Connection</h3>
- <ul>
- <p>The easiest way to <a name="management.properties">configure the
- JVM Agent</a> for Secure Remote
- Connection is to use your own <a
- href="http://java.sun.com/javase/6/docs/technotes/guides/management/agent.html#properties"
- title="This page describes the properties you can put in your management.properties file"
- >management.properties</a> file.
- In this example, we have copied the default
- <code>$JRE/conf/management/management.properties</code>
- file to the example's <code>src/etc</code> directory and
- modified it in <a href="src/etc/management.properties"
- title="our modified management.properties"
- >this way</a>:
- <ul>
- <li>We have set the RMI port to <u>4545</u> - this is just a
- random port number we have picked up. Feel free to use your
- own value suited to your environment.
- <pre># For setting the JMX RMI agent port use the following line
-com.sun.management.jmxremote.port=<b>4545</b></pre>
- </li>
- <li>We have <u>switched on</u> SSL <u>mutual authentication</u>
- <pre># For RMI monitoring with SSL client authentication use the following line
-com.sun.management.jmxremote.ssl.<b>need.client.auth</b>=<b>true</b></pre>
- </li>
- <li>We have also <u>secured the RMI Registry</u> with SSL
- <pre># For using an SSL/TLS <b>protected</b> RMI Registry use the following line
-com.sun.management.jmxremote.<b>registry.ssl</b>=<b>true</b></pre>
- </li>
- <li>We have provided <a
- href="src/etc/password.properties">our own password file</a>
- <pre># For a non-default password file location use the following line
-com.sun.management.jmxremote.password.file=<i>src/etc/password.properties</i></pre>
- </li>
- <li>We have provided <a
- href="src/etc/access.properties">our own access file</a>
- <pre># For a non-default password file location use the following line
-com.sun.management.jmxremote.access.file=<i>src/etc/access.properties</i></pre>
- </li>
- </ul>
- <p>You will note that we haven't provided any value
- for the other security properties, like
- <code>com.sun.management.jmxremote.authenticate=true</code>,
- because these properties already default to a value
- which enables security by default.
- Note however that protecting the RMI Registry with SSL
- improves the application security, but only as long as
- mutual authentication is also switched on. Otherwise, just
- anybody would be able to connect to the registry and
- get the RMIServer stub.
- </p>
- <p>We do recommend that you <u>use the most secure configuration
- when you deploy a JMX agent</u> - which means <u>switching on
- SSL protection for the RMI registry</u> <b>and</b> <u>requiring
- mutual authentication</u>, as we show in this example.
- </p>
- <p>We will use the <code>com.sun.management.config.file</code>
- system property to pass our <a
- href="src/etc/management.properties">management.properties</a>
- file to the <code>ScanDirAgent</code>.
- </p>
- </ul>
-
- <h3>Creating a password and access file</h3>
- <ul>
- <p>As explained above, we have created our own
- <a href="src/etc/password.properties">password file</a>
- and <a href="src/etc/access.properties">access file</a>
- for <a name="password-access">access control and authorization</a>.
- </p>
- <p>In the password file, we have defined two logins:
- <i>guest</i> and <i>admin</i>. The password for
- <i>guest</i> is <i>guestpasswd</i> and the password
- for <i>admin</i> is <i>adminpasswd</i>.
- </p>
- <p>In the access file, we have mapped these two logins
- to access rights: the <i>admin</i> login has <i>read-write</i>
- access, while the <i>guest</i> login only has <i>read-only</i>.
- </p>
- <p>Before starting the <code>ScanDirAgent</code>, you will
- need to restrict access permission to the password file,
- in such a way that nobody but you can read it. Otherwise, the
- JVM Agent will refuse to start the JMXConnectorServer, as it will
- fear that security can be compromised if other parties can
- have read access to the password file. How to restrict
- read access to the password file is explained in detail
- <a href="http://java.sun.com/javase/6/docs/technotes/guides/management/agent.html#PasswordAccessFiles"
- title="Using Password and Access Files"
- >here</a>.
- </p>
- <p>As we have seen above, the location
- of our access and password files is configured in our own <a
- href="src/etc/management.properties">management.properties</a>
- file.
- </p>
- </ul>
- <h3>Keystore and Truststore</h3>
- <ul>
- <p>Using SSL with mutual authentication means that both
- client and server will need a <a name="keystore-truststore"
- >keystore and a truststore</a>
- to store their own certificates, and the certificates of
- the parties they trust. Usually, client and server will
- have their own keystore and truststore.
- </p>
- <p>For the sake of simplicity - and to get you started
- without the tedious necessity of creating your own keystore
- and truststore, we are providing a dummy keystore and
- truststore, containing a certificate self-signed by duke.
- The password for our keystore is <i>password</i>, and the
- password for our truststore is <i>trustword</i>.
- We suggest that you first get the example running with the
- keystore and truststore we are providing before attempting
- to use your own keystore and truststore.
- </p>
- <p>A secure application will obviously need to use its own
- keystore and truststore, <b><u>and should not rely on the keystore
- and truststore we are providing here!</u></b>
- </p>
- <p>How to create your own keystore and truststore, is explained
- in <a
-href="http://java.sun.com/javase/6/docs/technotes/guides/management/agent.html#SSL_enabled"
-title="Monitoring and Management Using JMX"
- >here</a>.
- As shown <a href="#start-secure-agent">later</a>,
- we will need to use <a
- href="http://java.sun.com/javase/6/docs/technotes/guides/management/agent.html#SSL_enabled"
- >system properties</a> to pass our truststore
- and keystore to the <code>ScanDirAgent</code>.

- <p>If you start jconsole now, you will see that you
- are still able to connect to the agent using the
- local connection. However, if you try to connect
- through the remote connector, using
- <a href="docfiles/remote-connection.jpg">localhost:4545</a>,
- the connection will <a href="docfiles/remote-connection-failed.jpg"
- >fail</a>, even if you provide a correct login/password
- pair. Indeed, since the JMXConnectorServer is now protected with SSL,
- jconsole must also be configured with the appropriate SSL parameters
- so that it can authenticate the server and get authenticated by the
- server too as the SSL configuration of the server requires mutual
- authentication.
- </p>
- <p>The next section will discuss how to connect to the
- secure agent.
- </p>
- </ul>
-
- <h2><a name="h2-Connecting">Connecting to the Secure JMX Application</a></h2>
- <ul>
- <p>We will now see how to connect to the secure agent,
- using jconsole, and using a programmatic client.
- </p>
- </ul>
-
- <h3>Using jconsole to connect to the secure agent</h3>
- <ul>
- <p>The only special thing you need to do in order to
- be able to connect to your secure agent with
- jconsole, is to give it a keystore (containing
- its client certificate) and a truststore (containing
- the certificates of the servers it can trust).
- In our example, we use the same keystore/truststore
- pair on the client and server side - but this is
- not what a real application would do.
- Indeed a real application would have different
- certificates for the client and the server, and
- thus use different keystores (and probably truststores).
- More information on SSL authentication can be obtained from the <a
- href="http://java.sun.com/javase/6/docs/technotes/guides/security/jsse/JSSERefGuide.html#HowSSLWorks"
- title="How SSL Works"
- >Java™ Secure Socket Extension (JSSE) Reference Guide</a>.
- </p>
- <p>To start jconsole with our provided keystore and
- truststore, go to the scandir example root directory and
- type in the following command:
- <p><code>jconsole
- -J-Djava.util.logging.config.file=logging.properties
- -J-Djavax.net.ssl.keyStore=keystore
- -J-Djavax.net.ssl.keyStorePassword=password
- -J-Djavax.net.ssl.trustStore=truststore
- -J-Djavax.net.ssl.trustStorePassword=trustword</code></p>
- </p>
- <p>The <code>-J-Djava.util.logging.config.file=logging.properties</code>
- flag is not mandatory, but passing a <code>logging.properties</code>
- may help you debug connection problems if anything goes wrong.
- </p>
- <p>In jconsole connection window, choose to connect to a
- remote process, using the address <i>localhost:4545</i>
- and the guest login:
- </p>
- <p><center><a href="docfiles/remote-connection.jpg"
- ><img src="docfiles/remote-connection.jpg"
- alt="jconsole connection window"/></a></center>
- </p>
- <p>You will see that the agent will let view all the
- MBeans and their attributes, but will reject any
- attribute modification or remote method invocation.
- </p>
- <hr>
- <p><u>Note:</u> if jconsole fails to connect and show
- you <a href="docfiles/remote-connection-failed.jpg">this screen</a>
- you have probably misspelled some of the properties on jconsole
- command line, or you didn't start jconsole from the
- scandir example root directory where our <code>truststore</code>
- and <code>keystore</code> files are located. This article - <a
- href="http://blogs.sun.com/roller/page/jmxetc?entry=troubleshooting_connection_problems_in_jconsole"
- title="Troubleshooting connection problems in JConsole"
- >Troubleshooting connection problems in JConsole</a> - may help
- you figure out what is going wrong.
- </p>
- <hr>
- </ul>
-
- <h3>Writing a programmatic client to connect to the secure agent</h3>
- <ul>
- <p>
- In this section we will show the steps involved in writing
- a programmatic client that will connect to our secure agent.
- </p>
- <p>The <a
-href="dist/javadoc/com/sun/jmx/examples/scandir/ScanDirClient.html"
-title="The ScanDirClient class is a very short example of secure programmatic client"
- >ScanDirClient</a> is an example class that shows how a
- programmatic client can connect to a secured <i>scandir</i> application.
- This class contains a <code>main</code> method which creates and
- configures a <code>JMXConnector</code> client to connect with
- the secured <i>scandir</i> agent.
- </p>
- <p>The secure client differs only from a non secure client in
- so far as it needs to use SSL RMI Factories and credentials to
- connect to the secure agent. The steps required mainly involve:
- <ul>
- <li>Creating an empty environment map:
- <pre>
- // Create an environment map to hold connection properties
- // like credentials etc... We will later pass this map
- // to the JMX Connector.
- //
- System.out.println("\nInitialize the environment map");
- final Map<String,Object> env = new HashMap<String,Object>();
- </pre>
- </li>
- <li>Putting the client's credentials in that map:
- <i>(here the client will log in as <b>guest</b>)</i>
- <pre>
- // Provide the credentials required by the server
- // to successfully perform user authentication
- //
- final String[] credentials = new String[] { "guest" , "guestpasswd" };
- env.put("jmx.remote.credentials", credentials);
- </pre>
- </li>
- <li>Providing an <code>SslRMIClientSocketFactory</code> to interact
- with the secure RMI Registry:
- <pre>
- // Provide the SSL/TLS-based RMI Client Socket Factory required
- // by the JNDI/RMI Registry Service Provider to communicate with
- // the SSL/TLS-protected RMI Registry
- //
- env.put("com.sun.jndi.rmi.factory.socket",
- new SslRMIClientSocketFactory());
- </pre>
- </li>
- <li>Creating a JMXConnector and connecting with the
- secure server:
- <pre>
- // Create the RMI connector client and
- // connect it to the secure RMI connector server.
- // args[0] is the server's host - localhost
- // args[1] is the secure server port - 4545
- //
- System.out.println("\nCreate the RMI connector client and " +
- "connect it to the RMI connector server");
- final JMXServiceURL url = new JMXServiceURL(
- "service:jmx:rmi:///jndi/rmi://"+args[0]+":"+args[1]+
- "/jmxrmi");
- final JMXConnector jmxc = JMXConnectorFactory.connect(url, env);
- </pre>
- </li>
- </ul>
- <p>For this to work, we also need to start the <code>ScanDirClient</code>
- with the appropriate system properties that will point to our
- <code>keystore</code> and <code>truststore</code>. To start the secure
- client, go to the <i>scandir</i> example root directory and type
- the following command:
- <p><code>ant jar<br>
-java
- -Djava.util.logging.config.file=logging.properties
- -Djavax.net.ssl.keyStore=keystore
- -Djavax.net.ssl.keyStorePassword=password
- -Djavax.net.ssl.trustStore=truststore
- -Djavax.net.ssl.trustStorePassword=trustword
- -classpath dist/jmx-scandir.jar
- com.sun.jmx.examples.scandir.ScanDirClient localhost 4545
- </code></p>
- </p>
- <p>You should be seeing this trace:
-<center><table width="90%" border="0" bgcolor="#eeeeee">

- <p>If the <code>ScanDirClient</code> fails to connect with
- the secure agent, then this article - <a
- href="http://blogs.sun.com/roller/page/jmxetc?entry=troubleshooting_connection_problems_in_jconsole"
- title="Troubleshooting connection problems in JConsole"
- >Troubleshooting connection problems in JConsole</a> - may help
- you figure out what is going wrong. Indeed the connection steps
- performed by the <code>ScanDirClient</code> are very similar to
- those performed by <code>jconsole</code>, and the problems you
- could encounter are identical. Just remember that
- <code>jconsole</code> needs the extra <code>-J</code> flag to pass
- system properties to the VM, which is not needed with regular
- <code>java</code> launcher invocations.

- JMX agent in a production environment.
- We have also shown how to connect to such a
- secure agent with both jconsole and a programmatic
- client. We have also discuss various JMX
- design-patterns and best practices.

- * <p>

- * Logged results are logged by sending them to the {@link ResultLogManager}.
- * </p>

-# Default Access Control File for Remote JMX(TM) Monitoring
-######################################################################
-#
-# Access control file for Remote JMX API access to monitoring.
-# This file defines the allowed access for different roles. The
-# password file (jmxremote.password by default) defines the roles and their
-# passwords. To be functional, a role must have an entry in
-# both the password and the access files.
-#
-# Default location of this file is $JRE/conf/management/jmxremote.access
-# You can specify an alternate location by specifying a property in
-# the management config file $JRE/conf/management/management.properties
-# (See that file for details)
-#
-# The file format for password and access files is syntactically the same
-# as the Properties file format. The syntax is described in the Javadoc
-# for java.util.Properties.load.
-# Typical access file has multiple lines, where each line is blank,
-# a comment (like this one), or an access control entry.
-#
-# An access control entry consists of a role name, and an
-# associated access level. The role name is any string that does not
-# itself contain spaces or tabs. It corresponds to an entry in the
-# password file (jmxremote.password). The access level is one of the
-# following:
-# "readonly" grants access to read attributes of MBeans.
-# For monitoring, this means that a remote client in this
-# role can read measurements but cannot perform any action
-# that changes the environment of the running program.
-# "readwrite" grants access to read and write attributes of MBeans,
-# to invoke operations on them, and to create or remove them.
-# This access should be granted to only trusted clients,
-# since they can potentially interfere with the smooth
-# operation of a running program
-#
-# A given role should have at most one entry in this file. If a role
-# has no entry, it has no access.
-# If multiple entries are found for the same role name, then the last
-# access entry is used.
-#
-#
-# Default access control entries:
-# o The "monitorRole" role has readonly access.
-# o The "controlRole" role has readwrite access.
-#
-# monitorRole readonly
-# controlRole readwrite
-
-guest readonly
-admin readwrite

-# This is usefull when running on machines which have several
-# interfaces defined. It makes it possible to listen to a specific
-# subnet accessible through that interface.
-# Default for this property is "localhost".
-#
-# The format of the value for that property is any string accepted

-com.sun.management.jmxremote.ssl.need.client.auth=true
-
-# com.sun.management.jmxremote.registry.ssl=true|false
-# Default for this property is false. (Case for true/false ignored)

-# If the two properties below are true at the same time, i.e.
-# com.sun.management.jmxremote.ssl=true
-# com.sun.management.jmxremote.registry.ssl=true
-# then the RMIServer remote object and the RMI registry are

-
-#
-# ################ RMI Login configuration ###################
-#
-# com.sun.management.jmxremote.login.config=<config-name>
-# Specifies the name of a JAAS login configuration entry to use when
-# authenticating users of RMI monitoring.
-#
-# Setting this property is optional - the default login configuration
-# specifies a file-based authentication that uses the password file.
-#
-# When using this property to override the default login configuration
-# then the named configuration entry must be in a file that gets loaded

-A Simple Chat Server Example
-
-INTRODUCTION
-============
-This directory contains a very simple chat server, the server takes input from a
-socket ("user") and sends it to all other connected sockets ("users") along with
-the provided name the user was asked for when first connecting.
-
-The server was written to demonstrate the asynchronous I/O API in JDK 7.
-The sample assumes the reader has some familiarity with the subject matter.
-
-SETUP
-=====
-
-The server must be built with version 7 (or later) of the JDK.
-The server is built with:
-
- % mkdir build
- % javac -source 7 -target 7 -d build *.java
-
-EXECUTION
-=========
-
- % java -classpath build ChatServer [-port <port number>]
-
- Usage: ChatServer [options]
- options:
- -port port port number
- default: 5000
-
-CLIENT EXECUTION
-================
-
-No client binary is included in the sample.
-Connections can be made using for example the telnet command or any program
-that supports a raw TCP connection to a port.
-
-SOURCE CODE OVERVIEW
-====================
-ChatServer is the main class, it handles the startup and handles incoming
-connections on the listening sockets. It keeps a list of connected client
-and provides methods for sending a message to them.
-
-Client represents a connected user, it provides methods for reading/writing
-from/to the underlying socket. It also contains a buffer of input read from
-the user.
-
-DataReader provides the interface of the two states a user can
-be in. Waiting for a name (and not receiving any messages while doing so, implemented
-by NameReader) and waiting for messages from the user (implemented by MessageReader).
-
-ClientReader contains the "main loop" for a connected client.
-
-NameReader is the initial state for a new client, it sends the user a string and
-waits for a response before changing the state to MessageReader.
-
-MessageReader is the main state for a client, it checks for new messages to send to
-other clients and reads messages from the client.
-
-FINALLY
-=======
-This is a sample: it is not production quality and isn't optimized for performance.

-/**
- * A helper class which performs I/O using the SSLEngine API.
- * <P>
- * Each connection has a SocketChannel and a SSLEngine that is
- * used through the lifetime of the Channel. We allocate byte buffers
- * for use as the outbound and inbound network buffers.
- *
- * <PRE>
- * Application Data
- * src requestBB
- * | ^
- * | | |
- * v | |
- * +----+-----|-----+----+
- * | | |
- * | SSL|Engine |
- * wrap() | | | unwrap()
- * | OUTBOUND | INBOUND |
- * | | |
- * +----+-----|-----+----+
- * | | ^
- * | | |
- * v |
- * outNetBB inNetBB
- * Net data
- * </PRE>
- *
- * These buffers handle all of the intermediary data for the SSL
- * connection. To make things easy, we'll require outNetBB be
- * completely flushed before trying to wrap any more data, but we
- * could certainly remove that restriction by using larger buffers.
- * <P>
- * There are many, many ways to handle compute and I/O strategies.
- * What follows is a relatively simple one. The reader is encouraged
- * to develop the strategy that best fits the application.
- * <P>
- * In most of the non-blocking operations in this class, we let the
- * Selector tell us when we're ready to attempt an I/O operation (by the
- * application repeatedly calling our methods). Another option would be
- * to attempt the operation and return from the method when no forward
- * progress can be made.
- * <P>
- * There's lots of room for enhancements and improvement in this example.
- * <P>
- * We're checking for SSL/TLS end-of-stream truncation attacks via
- * sslEngine.closeInbound(). When you reach the end of a input stream
- * via a read() returning -1 or an IOException, we call
- * sslEngine.closeInbound() to signal to the sslEngine that no more
- * input will be available. If the peer's close_notify message has not
- * yet been received, this could indicate a trucation attack, in which
- * an attacker is trying to prematurely close the connection. The
- * closeInbound() will throw an exception if this condition were
- * present.

- A Simple NIO-based HTTP/HTTPS Server Example
-
-
-INTRODUCTION
-============
-This directory contains a simple HTTP/HTTPS server. HTTP/HTTPS are two
-common network protocols that provide for data transfer, and are more
-fully described in RFC 2616 and RFC 2818 (Available at
-http://www.ietf.org ). HTTPS is essentially HTTP after the connection
-has been secured with SSL/TLS. TLS is the successor to SSL, and is
-described in RFC 2246.
-
-This server was written to demonstrate some of the functionality new to
-the Java 2 platform. The demo is not meant to be a full tutorial, and
-assumes the reader has some familiarity with the subject matter.
-
-In particular, it shows:
-
- New I/O (java.nio, java.nio.channels, java.util.regex, java.nio.charset)
-
- Introduced in version 1.4 of the platform, NIO was designed to
- overcome some of the scalability limitations found in the
- existing blocking java.net.* API's, and to address other
- concepts such as Regular Expression parsing and Character
- Sets.
-
- This server demonstrates:
-
- ByteBuffer
- Blocking and Non-Blocking I/O
- SocketChannel
- ServerSocketChannel
- Selector
- CharacterSet
- Pattern matching using Regular Expressions
-
- JSSE (javax.net.ssl)
-
- Introduced in version 1.4 of the platform, JSSE provides
- network security using SSL/TLS for java.net.Socket-based
- traffic. In version 1.5, the SSLEngine API was introduced
- which separates the SSL/TLS functionality from the underlying
- I/O model. By making this separation, applications can adapt
- I/O and compute strategies to best fit their circumstances.
-
- This server demonstrates:
-
- Using SSLEngine to create a HTTPS server
- Creating simple key material for use with HTTPS
-
- Concurrency Library (java.util.concurrent)
-
- Introduced in version 1.5 of the platform, the concurrency
- library provides a mechanism which decouples task submission
- from the mechanics of how each task will be run.
-
- This server demonstrates:
-
- A ThreadPool with a fixed number of threads, which is
- based on the number of available processors.
-
-
-SETUP
-=====
-
-The server must be built on version 1.5 (or later) of the platform.
-Invoking the following should be sufficient:
-
- % mkdir build
- % javac -d build *.java
-
-The following creates the document root:
-
- % mkdir root
-
-All documents should be placed in this directory.
-
-For HTTPS, the server authenticates itself to clients by using simple
-Public Key Infrastructure (PKI) credentials in the form of
-X509Certificates. You must create the server's credentials before
-attempting to run the server in "-secure" mode. The server is
-currently hardcoded to look for its credentials in a file called
-"testkeys".
-
-In this example, we'll create credentials for a fictional widget web
-site owned by the ubiquitous "Xyzzy, Inc.". When you run this in your
-own environment, replace "widgets.xyzzy.com" with the hostname of your
-server.
-
-The easiest way to create the SSL/TLS credentials is to use the
-java keytool, by doing the following:
-
- (<CR> represents your end-of-line key)
-
- % keytool -genkey -keyalg rsa -keystore testkeys -alias widgets
- Enter keystore password: passphrase
- What is your first and last name?
- [Unknown]: widgets.xyzzy.com<CR>
- What is the name of your organizational unit?
- [Unknown]: Consumer Widgets Group<CR>
- What is the name of your organization?
- [Unknown]: Xyzzy, Inc.<CR>
- What is the name of your City or Locality?
- [Unknown]: Arcata<CR>
- What is the name of your State or Province?
- [Unknown]: CA<CR>
- What is the two-letter country code for this unit?
- [Unknown]: US<CR>
- Is CN=widgets.xyzzy.com, OU=Consumer Widgets Group, O="Xyzzy, Inc.",
- L=Arcata, ST=CA, C=US correct?
- [no]: yes<CR>
-
- Enter key password for <mykey>
- (RETURN if same as keystore password): <CR>
-
-This directory also contain a very simple URL reader (URLDumper), which
-connects to a specified URL and places all output into a specified file.
-
-
-SERVER EXECUTION
-================
-
- % java -classpath build Server N1
-
- Usage: Server <type> [options]
- type:
- B1 Blocking/Single-threaded Server
- BN Blocking/Multi-threaded Server
- BP Blocking/Pooled-thread Server
- N1 Nonblocking/Single-threaded Server
- N2 Nonblocking/Dual-threaded Server
-
- options:
- -port port port number
- default: 8000
- -backlog backlog backlog
- default: 1024
- -secure encrypt with SSL/TLS
- default is insecure
-
-"http://" URLs should be used with insecure mode, and
-"https://" for secure mode.
-
-The "B*" servers use classic blocking I/O: in other words, calls to
-read()/write() will not return until the I/O operation has completed. The
-"N*" servers use non-blocking mode and Selectors to determine which
-Channels are ready to perform I/O.
-
-B1: A single-threaded server which completely services each
- connection before moving to the next.
-
-B2: A multi-threaded server which creates a new thread for each
- connection. This is not efficient for large numbers of
- connections.
-
-BP: A multi-threaded server which creates a pool of threads for use
- by the server. The Thread pool decides how to schedule those
- threads.
-
-N1: A single-threaded server. All accept() and read()/write()
- operations are performed by a single thread, but only after
- being selected for those operations by a Selector.
-
-N2: A dual-threaded server which performs accept()s in one thread, and
- services requests in a second. Both threads use select().
-
-
-CLIENT EXECUTION
-================
-You can test the server using any standard browser such as Internet
-Explorer or Mozilla, but since the browser will not trust the
-credentials you just created, you may need to accept the credentials
-via the browser's pop-up dialog box.
-
-Alternatively, to use the certificates using the simple included JSSE
-client URLDumper, export the server certificate into a new truststore,
-and then run the application using the new truststore.
-
- % keytool -export -keystore testkeys -alias widgets -file widgets.cer
- Enter keystore password: passphrase<CR>
- Certificate stored in file <widgets.cer>
-
- % keytool -import -keystore trustCerts -alias widgetServer \
- -file widgets.cer
- Enter keystore password: passphrase<CR>
- Owner: CN=widgets.xyzzy.com, OU=Consumer, O="xyzzy, inc.", L=Arcata,
- ST=CA, C=US
- Issuer: CN=widgets.xyzzy.com, OU=Consumer, O="xyzzy, inc.",

-
-SOURCE CODE OVERVIEW
-====================
-
-The main class is Server, which handles program startup, and is
-subclassed by the "B*" and "N*" server classes.
-
-Following a successful accept(), the "B*" variants each create a
-RequestServicer object to perform the actual request/reply operations. The
-primary differences between the different "B*" servers is how the
-RequestServicer is actually run:
-
- B1: RequestServicer.run() is directly called.
- BN: A new thread is started, and the thread calls RequestServicer.run().
- BP: A ThreadPool is created, and the pool framework is given Runnable
- tasks to complete.
-
-In the "N*" variations, a Dispatcher object is created, which is
-responsible for performing the select, and then issuing the
-corresponding handler:
-
- N1: A single thread is used for all accept()/read()/write() operations
- N2: Similar to N1, but a separate thread is used for the accept()
- operations.
-
-In all cases, once the connection has been accepted, a ChannelIO object
-is created to handle all I/O. In the insecure case, the corresponding
-SocketChannel methods are directly called. However in the secure case,
-more manipulations are needed to first secure the channel, then
-encrypt/decrypt the data, and finally properly send any shutdown
-messages. ChannelIOSecure extends ChannelIO, and provides the secure
-variants of the corresponding ChannelIO calls.
-
-RequestServicer and RequestHandler are the main drivers for the
-blocking and non-blocking variants, respectively. They are responsible
-for:
-
- Performing any initial handshaking
-
- Reading the request data
- All data is stored in a local buffer in the ChannelIO
- structure.
-
- Parsing the request
- The request data is obtained from the ChannelIO object, and
- is processed by Request class, which represents the
- parsed URI address.
-
- Locating/preparing/sending the data or reporting error conditions.
- A Reply object is created which represents the entire object to send,
- including the HTTP/HTTPS headers.
-
- Shutdown/closing the channel.
-
-
-CLOSING THOUGHTS
-================
-This example represents a simple server: it is not production quality.
-It was primarily meant to demonstrate the new APIs in versions 1.4 and
-1.5 of the platform.
-
-This example could certainly be expanded to address other areas of
-concern: for example, assigning multiple threads to handle the selected
-Channels, or delegating SSLEngine tasks to multiple threads. There are
-so many ways to implement compute and I/O strategies, we encourage you
-to experiment and find what works best for your situation.
-
-To steal a phrase from many textbooks:
-
- "It is left as an exercise for the reader..."

-Scriptpad Sample
-
-* Introduction
-
-Scriptpad is a notepad like editor to open/edit/save and run
-script (JavaScript) files. This sample demonstrates the use of
-javax.script (JSR-223) API and JavaScript engine that is bundled
-with JDK 6.
-
-Scriptpad sample demonstrates how to use Javascript to use Java
-classes and objects to perform various tasks such as to modify,
-customize Swing GUI or to connect to a running application and
-monitor it using JMX (Java Management Extensions) API.
-
-* How to run Scriptpad?
-
-Scriptpad can be run with the following command:
-
- java -jar ./build/scriptpad.jar
-
-(be sure to use the correct version of java). You can
-open/edit/save scripts using menu items under "File" menu.
-To run currently edited script, you can use "Tools->Run" menu.
-
-For example, you may enter
-
- alert("hello, world");
-
-in the editor and run the same with "Tools->Run" menu.
-You will see an alert box with the message "hello, world".
-
-In addition to being a simple script editor/runner, scriptpad
-can be used to connect to a JMX MBean server ("Tools->JMX Connect"
-menu). User can specify JMX hostname and port. After connecting,
-user can use "monitoring and management" script functions defined
-in "mm.js" (see below).
-
-* Scriptpad Sources
-
-com.sun.demo.scriptpad.Main class is the entry point of this
-sample. This class creates ScriptEngine and evaluates few
-JavaScript "files" -- which are stored as resources (please
-refer to src/resources/*.js). Actual code for the scriptpad's
-main functionality lives in these JavaScript files.
-
-1. conc.js
- -- simple concurrency utilities for JavaScript
-
-2. gui.js
- -- simple GUI utilities for JavaScript
-
-3. mm.js
- -- Monitoring and Management utilities for JavaScript
-
-4. scriptpad.js
- -- This creates main "notepad"-like GUI for open/edit/save
- and run script files
-
-5. Main.js
- -- This script file can be used under "jrunscript" tool.
- jrunscript is an experimental tool shipped with JDK (under
- $JDK_HOME/bin directory). The scriptpad application can be
- run by the following commands:
-
- cd ./src/resources
- $JDK_HOME/bin/jrunscript -f Main.js -f -
-
-
-* Extending Scriptpad:
-
-It is possible to extend scriptpad using scripts. There is a global
-object called "application". This object has 2 fields and a method.
-
- Fields of the application object:
-
- frame -> JFrame of the scriptpad
- editor -> editor pane of the scriptpad
-
- Method of the application object:
-
- addTool -> adds a menu item under "Tools" menu
-
- Example script to add "Tools->Hello" menu item:
-
- application.addTool("Hello",
- function() { alert("hello, world"); });
-
-After running the above script, you can click Tools->Hello menu item
-and you'll see an alert box.
-
-Scriptpad customization may also be done by defining a file named
-"scriptpad.js" under your home directory,. If this file is found,
-scriptpad loads this file just after initializating everything.
-In your initialization file, you can additional script functions
-by "load" function.
-
-* Script Samples:
-
-On clicking the menu items under "Examples" menu, scriptpad shows
-built-in examples in the editor. Also, there are few script samples
-under the ./src/scripts directory.
-
-* Monitoring and Management with Scriptpad:
-
-(1) Start the application with the JMX agent - here's an example of
- how the Java2D demo is started
-
- java -Dcom.sun.management.jmxremote.port=1090 \
- -Dcom.sun.management.jmxremote.ssl=false \
- -Dcom.sun.management.jmxremote.authenticate=false \
- -jar $JDK_HOME/demo/jfc/Font2DTest/Font2DTest.jar
-
-(2) Start scriptpad and click on "Tools->JMX Connect" menu.
- In the prompt, enter "localhost:1090" to connect to the above
- program.
-
-After connecting to a MBeanServer (using "Tools->JMX Connect"),
-you can run any script that uses functions defined in "mm.js".
-For example, it is possible to load and run management scripts that
-are part of JConsole script shell plugin under the directory:
-
- $JDK_HOME/demo/scripting/jconsole-plugin/src/scripts

-Sample scripts:
-
-(1) browse.js
-
- -- Open and run this script in scriptpad. You will see
- Tools->Browse menu. Using this you can start your
- desktop default browser with the given URL.
-
-(2) insertfile.js
-
- -- Open and run this script in scriptpad. You will see
- "Tools->Insert File..." menu. Using this you can start
- insert content of a selected file into currently
- edited document
-
-(3) linewrap.js
-
- -- Open and run this script in scriptpad. You will see
- "Tools->Line Wrap" menu. Using this you can toggle
- the line wrapping mode of the editor
-
-(4) mail.js
-
- -- Open and run this script in scriptpad. You will see
- Tools->Mail menu. Using this you can start your
- desktop default mail client with the given "To" mail id.
-
-(5) memmonitor.js
-
- -- This is a simple Monitoring & Management script. To use this,
- you need an application to monitor. You can use memory.bat
- or memory.sh in the current directory to start an application
- that will be monitored. After that please follow these steps:
-
- 1. Start the target application using memory.sh or memory.bat
- 2. Start scriptpad
- 3. Use "Tools->JMX Connect" menu and specify "localhost:1090"
- to connect
- 4. Open "memmonitor.js" and run it (using "Tools->Run")
- in scriptpad
- 5. A new "Tools-Memory Monitor" menu appears. Use this menu
- and specify 4 and 500 as threshold and interval values.
- 6. In the target application shell (where memory.bat/.sh was
- started), enter an integer value and press "enter".
- 7. You'll see an alert box from scriptpad -- alerting you for
- memory threshold exceeded!
-
-(6) textcolor.js
-
- -- Open and run this script in scriptpad. You will see
- "Tools->Selected Text Color..." menu. Using this you
- change the color of "selected text" in the editor.

-This sample provides Java "Hello World" program that is invoked
-from C# application in the same process.
-
-The problem of direct call of the JVM API from CLR applications
-by PInvoke interface is the JVM API functions do not have static
-adresses, they need to be got by JNI_CreateJavaVM() call.
-The sample contains C++ libraty that wraps JVM API calls by the
-static functions that are called from the C# application by
-PInvoke interface.
-
-The sample contains the following files:
-
-Makefile - make file
-README.txt - this readme
-invoked.java - the invoked HelloWorld Java program
-invoker.cs - C# invoker application
-jinvoker.cpp - C++ wrapper
-jinvokerExp.h - wrapper library exports
-
-After the success making the following files are produced:
-
-invoked.class - the compiled HelloWorld class
-invoker.exe - the executable .NET program that invokes Java
-jinvoker.dll - the wrapper library
-
-The following environment needs to be set for the correct sample
-build and execution:
-
-INCLUDE must contain the paths to:
- 1. MS Visual C++ standard include
- 2. .NET SDK include
- 3. Java includes
- Example: %MSDEV%/VC98/Include;%DOTNET%/Include;%JAVA_HOME%/include;%JAVA_HOME%/include/win32
-
-LIB must contain the paths to:
- 1. MS Visual C++ standard libraries
- 2. .NET SDK libraries
- 3. jvm.dll
- Example: %MSDEV%/VC98/Lib;%DOTNET%/Lib;%JAVA_HOME%/jre/bin/client
-
-PATH must contain the paths to:
- 1. MS Visual C++ standard bin
- 2. MS Dev common bin
- 3. .NET SDK libraries
- 4. Java bin
- 5. jvm.dll
- Example: %MSDEV%/VC98/Bin;%MSDEV%/Common/MSDev98/Bin;%DOTNET%/Lib;%JAVA_HOME%/bin;%JAVA_HOME%/jre/bin/client;%PATH%
-
-To run the sample please do:
-
- invoker.exe invoked

-This sample provides C# "Hello World" program that is invoked
-from Java application in the same process.
-
-There is no way to invoke .NET methods from Java classes directly,
-it is necessary to use native code level.
-The sample contains C++ library that can invoke any .NET program by mscorlib library.
-Using the JNI the Java application invokes the C# "Hello World".
-
-The sample contains the following files:
-
-Makefile - make file
-README.txt - this readme
-invoked.cs - the invoked HelloWorld Java program
-invoker.java - C# invoker application
-invoker.cpp - C++ wrapper
-invokerExp.h - wrapper library exports
-invoker.h - javah generated file with the native method definition
-
-After the success making the following files are produced:
-
-invoked.exe - the executable HelloWorld .NET program
-invoker.class - the compiled Java class that invokes the .NET program
-invoker.dll - the wrapper library
-
-The following environment needs to be set for the correct sample
-build and execution:
-
-INCLUDE must contain the paths to:
- 1. MS Visual C++ standard include
- 2. .NET SDK include
- 3. Java includes
- Example: %MSDEV%/VC98/Include;%DOTNET%/Include;%JAVA_HOME%/include;%JAVA_HOME%/include/win32
-
-LIB must contain the paths to:
- 1. MS Visual C++ standard libraries
- 2. .NET SDK libraries
- Example: %MSDEV%/VC98/Lib;%DOTNET%/Lib
-
-PATH must contain the paths to:
- 1. MS Visual C++ standard bin
- 2. MS Dev common bin
- 3. .NET SDK libraries
- 4. Java bin
- Example: %MSDEV%/VC98/Bin;%MSDEV%/Common/MSDev98/Bin;%DOTNET%/Lib;%JAVA_HOME%/bin;%PATH%
-
-To run the sample please do:
-
-java invoker invoked.exe

-DTrace HotSpot probes samples
-=============================
-
-This directory contains the list of D scripts which could be used to trace
-Java application with help of Solaris(tm) 10 Dynamic Tracing (DTrace)
-probes.
-
-The directory is organized as:
-
-* helpers/
-
- This directory contains the auxiliary script to launch Java application
- with D script to debug. See more comments in the scripts.
-
-* hotspot/
-
- This directory contains D scripts which demonstrate usage of 'hotspot'
- provider probes.
-
-
-* hotspot_jni/
-
- This directory contains D scripts which demonstrate usage of 'hotspot_jni'
- provider probes.
-
-
-
-Requirements to run DTrace
-==========================
-
-1. dtrace framework should be installed; (check if /usr/sbin/dtrace exists)
-
-2. the user should have the following rights:
- dtrace_proc, dtrace_user, dtrace_kernel
-
- To give a user a privilege on login, insert a line into the
- /etc/user_attr file of the form:
- user-name::::defaultpriv=basic,dtrace_proc,dtrace_user,dtrace_kernel
-
- or
-
- To give a running process an DTrace privilege, use the ppriv(1) command:
- # ppriv -s A+privilege process-ID

- * Description:
- * dtrace -c option launches the command specified in the -c argument and
- * starts tracing the process. Typically, you can run a D script and trace
- * a Java application as follows:
- * dscript.d -Zc "java HelloWorld"
- *
- * The -Z option is needed to permit probe descriptions that match zero
- * probes because Hotspot probes definitions are located in libjvm.so which
- * has not been yet loaded and thus can't be enabled until the application
- * is started.
- *
- * Straightforward attempt to run D script may fail, e.g.:
- * dscript.d -c "java HelloWorld"
- * "probe description hotspotPID:::probename does not match any probes"
- *
- * This is because DTrace tries to enable probes before libjvm.so is loaded.
- * The -Z option requires Solaris patch 118822-30 installed on your system.
- *
- * In case you don't have this Solaris patch use dtrace_helper.d script.
- * This script waits until the Hotspot DTrace probes are loaded and then
- * stops the Java process (passed as '-c' options). After the process is
- * stopped, another D script (passed as first argument) is called to do real
- * trace of Java process.
- *
- * Usage example:
- * dtrace_helper.d -c "java ..." ../hotspot/class_loading_stat.d

-============================
-'hotspot' PROBES DESCRIPTION
-============================
-
-This directory contains D scripts which demonstrate usage of 'hotspot' provider probes.
-
-The 'hotspot' provider makes available probes that can be used to track the
-lifespan of the VM, thread start and stop events, GC and memory pool
-statistics, method compilations, and monitor activity. With a startup flag,
-additional probes are enabled which can be used to monitor the running Java
-program, such as method enter and return probes, and object allocations. All
-of the hotspot probes originate in the VM library (libjvm.so), so they are
-also provided from programs which embed the VM.
-
-Many of the probes in the provider have arguments that can be examined to
-provide further details on the state of the VM. Many of these probes'
-arguments are opaque IDs which can be used to link probe firings to each
-other, however strings and other data are also provided. When string values
-are provided, they are always present as a pair: a pointer to unterminated
-modified UTF-8 data (see JVM spec: 4.4.7) , and a length value which
-indicates the extent of that data. Because the string data (even when none
-of the characters are outside the ASCII range) is not guaranteed to be
-terminated by a NULL character, it is necessary to use the length-terminated
-copyinstr() intrinsic to read the string data from the process.
-
-You can find more information about HotSpot probes here:
-http://java.sun.com/javase/6/docs/technotes/guides/vm/dtrace.html
-
-
-===========
-THE SCRIPTS
-===========
-
-The following scripts/samples which demonstrate 'hotspot' probes usage are
-available:
-
-- class_loading_stat.d
- The script collects statistics about loaded and unloaded Java classes and
- dump current state to stdout every N seconds.
-
-- gc_time_stat.d
- The script measures the duration of a time spent in GC.
- The duration is measured for every memory pool every N seconds.
-
-- hotspot_calls_tree.d
- The script prints calls tree of fired 'hotspot' probes.
-
-- method_compile_stat.d
- The script prints statistics about N methods with largest/smallest
- compilation time every M seconds.
-
-- method_invocation_stat.d
- The script collects statistics about Java method invocations.
-
-- method_invocation_stat_filter.d
- The script collects statistics about Java method invocations.
- You can specify package, class or method name to trace.
-
-- method_invocation_tree.d
- The script prints tree of Java and JNI method invocations.
-
-- monitors.d
- The script traces monitor related probes.
-
-- object_allocation_stat.d
- The script collects statistics about N object allocations every M seconds.
-
-
-==========
-HOW TO RUN
-==========
-
-To run any D script from hotspot directory you can do either:
-
- # dscript.d -c "java ..."
-
- or if you don't have Solaris 10 patch which allows to specify probes that
- don't yet exist ( Hotspot DTrace probes are defined in libjvm.so and as
- result they could be not been yet loaded when you try to attach D script to
- the Java process) do:
-
- # ../helpers/dtrace_helper.d -c "java ..." dscript.d
-
- or if your application is already running you can just simply attach
- the D script like:
-
- # dscript.d -p JAVA_PID

-================================
-'hotspot_jni' PROBES DESCRIPTION
-================================
-
-This directory contains D scripts which demonstrate usage of 'hotspot_jni'
-provider probes.
-
-In order to call from native code to Java code, due to embedding of the VM
-in an application or execution of native code within a Java application, the
-native code must make a call through the JNI interface. The JNI interface
-provides a number of methods for invoking Java code and examining the state
-of the VM. DTrace probes are provided at the entry point and return point
-for each of these methods. The probes are provided by the hotspot_jni
-provider. The name of the probe is the name of the JNI method, appended with
-"-entry" for entry probes, and "-return" for return probes. The arguments
-available at each entry probe are the arguments that were provided to the
-function (with the exception of the Invoke* methods, which omit the
-arguments that are passed to the Java method). The return probes have the
-return value of the method as an argument (if available).
-
-You can find more information about HotSpot probes here:
-http://java.sun.com/javase/6/docs/technotes/guides/vm/dtrace.html
-
-===========
-THE SCRIPTS
-===========
-
-The following scripts/samples which demonstrate hotspot_jni probes usage are
-available:
-
-- CriticalSection.d
- Inspect a JNI application for Critical Section violations.
-
-- CriticalSection_slow.d
- Do the same as CriticalSection.d but provide more debugging info.
-
-- hotspot_jni_calls_stat.d
- This script collects statistics about how many times particular JNI method
- has been called.
-
-- hotspot_jni_calls_tree.d
- The script prints tree of JNI method calls.
-
-See more details in the scripts.
-
-
-==========
-HOW TO RUN
-==========
-To run any dscript from hotspot directory you can do either:
-
- # dscript.d -c "java ..."
-
- or if you don't have Solaris 10 patch which allows to specify probes that
- don't yet exist ( Hotspot DTrace probes are defined in libjvm.so and as
- result they could be not been yet loaded when you try to attach dscript to
- the Java process) do:
-
- # ../helpers/dtrace_helper.d -c "java ..." dscript.d
-
- or if your application is already running you can just simply attach
- the D script like:
-
- # dscript.d -p JAVA_PID
