Method Protocol (JRMP)

.SH DESCRIPTION

.PP

.PP

The \f[CB]rmic\f[R] compiler generates stub and skeleton class files using

the JRMP.

.PP

\f[B]Note:\f[R]

.PP

The rmic compiler has been updated to remove the \f[CB]\-idl\f[R] and

\f[CB]\-iiop\f[R] options and can no longer generate IDL or IIOP stubs and

tie classes.

.PP

JRMP class files are generated from compiled Java programming language

classes that are remote object implementation classes.

A remote implementation class is a class that implements the interface

\f[CB]java.rmi.Remote\f[R].

The class names in the \f[CB]rmic\f[R] command must be for classes that

were compiled successfully with the \f[CB]javac\f[R] command and must be

fully package qualified.

For example, running the \f[CB]rmic\f[R] command on the class file name

\f[CB]HelloImpl\f[R] as shown here creates the

\f[CB]HelloImpl_Stub.class\f[R] file in the \f[CB]hello\f[R] subdirectory

(named for the class\[aq]s package):

.RS

.PP

\f[CB]rmic\ hello.HelloImpl\f[R]

.RE

.PP

A skeleton for a remote object is a JRMP protocol server\-side entity

that has a method that dispatches calls to the remote object

implementation.

.PP

A stub is a client\-side proxy for a remote object that\[aq]s

responsible for communicating method invocations on remote objects to

the server where the actual remote object implementation resides.

A client\[aq]s reference to a remote object, therefore, is actually a

reference to a local stub.

.PP

By default, the \f[CB]rmic\f[R] command generates stub classes that use

the 1.2 JRMP stub protocol version only, as though the \f[CB]\-v1.2\f[R]

option were specified.

See \f[B]Options for the rmic Compiler\f[R].

.PP

A stub implements only the remote interfaces, and not local interfaces

that the remote object also implements.

Because a JRMP stub implements the same set of remote interfaces as the

remote object, a client can use the Java programming language built\-in

operators for casting and type checking.

.PP

\f[B]Note:\f[R]

.PP

The rmic compiler does not support reading of class files that have been

compiled with the \f[CB]\-\-enable\-preview\f[R] option, nor does it

support generation of stub or skeleton classes that have preview

features enabled.

.SH OPTIONS FOR THE RMIC COMPILER

.TP

.B \f[CB]\-bootclasspath\f[R] \f[I]path\f[R]

Overrides the location of bootstrap class files.

.RS

.RE

.TP

.B \f[CB]\-classpath\f[R] \f[I]path\f[R]

Specifies the path the \f[CB]rmic\f[R] command uses to look up classes.

This option overrides the default or the \f[CB]CLASSPATH\f[R] environment

variable when it is set.

Directories are separated by colons or semicolons, depending on your

operating system.

The following is the general format for \f[I]path\f[R]:

.RS

.IP \[bu] 2

\f[B]Oracle Solaris, Linux, and OS X:\f[R]

\f[CB]\&.:\f[R]\f[I]your_path\f[R], for example:

\f[CB]\&.:/usr/local/java/classes\f[R]

.IP \[bu] 2

\f[B]Windows:\f[R] \f[CB]\&.;\f[R]\f[I]your_path\f[R], for example:

\f[CB]\&.;/usr/local/java/classes\f[R]

.RE

.TP

.B \f[CB]\-d\f[R] \f[I]directory\f[R]

Specifies the root destination directory for the generated class

hierarchy.

You can use this option to specify a destination directory for the stub,

skeleton, and tie files.

.RS

.IP \[bu] 2

\f[B]Oracle Solaris, Linux, and OS X:\f[R] For example, the following

command places the stub and skeleton classes derived from

\f[CB]MyClass\f[R] into the directory \f[CB]/java/classes/exampleclass\f[R]:

.RS 2

.RS

.PP

\f[CB]rmic\ \-d\ /java/classes\ exampleclass.MyClass\f[R]

.RE

.RE

.IP \[bu] 2

\f[B]Windows:\f[R] For example, the following command places the stub and

skeleton classes derived from \f[CB]MyClass\f[R] into the directory

\f[CB]C:\\java\\classes\\exampleclass\f[R]:

.RS 2

.RS

.PP

\f[CB]rmic\ \-d\ C:\\java\\classes\ exampleclass.MyClass\f[R]

.RE

.RE

.PP

If the \f[CB]\-d\f[R] option isn\[aq]t specified, then the default

behavior is as though \f[CB]\-d\f[R] was specified.

The package hierarchy of the target class is created in the current

directory, and stub/tie/skeleton files are placed within it.

.RE

.TP

.B \f[CB]\-g\f[R]

Enables the generation of all debugging information, including local

variables.

By default, only line number information is generated.

.RS

.RE

.TP

.B \f[CB]\-J\f[R]\f[I]argument\f[R]

Used with any Java command, the \f[CB]\-J\f[R] option passes the

\f[I]argument\f[R] that follows it (no spaces between the \f[CB]\-J\f[R]

and the argument) to the Java interpreter.

.RS

.RE

.TP

.B \f[CB]\-keep\f[R] or \f[CB]\-keepgenerated\f[R]

Retains the generated \f[CB]\&.java\f[R] source files for the stub,

skeleton, and tie classes and writes them to the same directory as

the\f[CB]\&.class\f[R] files.

.RS

.RE

.TP

.B \f[CB]\-nowarn\f[R]

Turns off warnings.

When the \f[CB]\-nowarn\f[R] options is used, the compiler doesn\[aq]t

print warnings.

.RS

.RE

.TP

.B \f[CB]\-nowrite\f[R]

Doesn\[aq]t write compiled classes to the file system.

.RS

.RE

.TP

.B \f[CB]\-vcompat\f[R] (deprecated)

Generates stub and skeleton classes that are compatible with both the

1.1 and 1.2 JRMP stub protocol versions.

This option was the default in releases before 5.0.

The generated stub classes use the 1.1 stub protocol version when loaded

in a JDK 1.1 virtual machine and use the 1.2 stub protocol version when

loaded into a 1.2 (or later) virtual machine.

The generated skeleton classes support both 1.1 and 1.2 stub protocol

versions.

The generated classes are relatively large to support both modes of

operation.

.RS

.PP

\f[B]Note:\f[R]

.PP

This option has been deprecated.

See \f[B]Description\f[R].

.RE

.TP

.B \f[CB]\-verbose\f[R]

Causes the compiler and linker to print messages about what classes are

being compiled and what class files are being loaded.

.RS

.RE

.TP

.B \f[CB]\-v1.1\f[R] (deprecated)

Generates stub and skeleton classes for the 1.1 JRMP stub protocol

version only.

The \f[CB]\-v1.1\f[R] option is useful only for generating stub classes

that are serialization\-compatible with existing, statically deployed

stub classes generated by the \f[CB]rmic\f[R] command from JDK 1.1 that

can\[aq]t be upgraded (and dynamic class loading isn\[aq]t being used).

.RS

.PP

\f[B]Note:\f[R]

.PP

This option has been deprecated.

See \f[B]Description\f[R].

.RE

.TP

.B \f[CB]\-v1.2\f[R] (deprecated)

(Default) Generates stub classes for the 1.2 JRMP stub protocol version

only.

No skeleton classes are generated because skeleton classes aren\[aq]t

used with the 1.2 stub protocol version.

The generated stub classes don\[aq]t work when they\[aq]re loaded into a

JDK 1.1 virtual machine.

.RS

.PP

\f[B]Note:\f[R]

.PP

This option has been deprecated.

See \f[B]Description\f[R].

.B \f[CB]CLASSPATH\f[R]

Used to provide the system a path to user\-defined classes.
