+
+Introduction
+
+ Thank you for downloading this release of the Java(TM) 2 SDK,
+ Standard Edition. The Java 2 SDK is a development environment for
+ building applications, applets, and components that can be
+ deployed on the Java platform.
+
+ The Java 2 SDK software includes tools useful for developing and
+ testing programs written in the Java programming language and
+ running on the Java platform. These tools are designed to be used
+ from the command line. Except for appletviewer, these tools do not
+ provide a graphical user interface.
+
+
+Release Notes
+
+ See the Release Notes on the Java Software web site for additional
+ information pertaining to this release.
+
+ http://java.sun.com/j2se/1.4.2/relnotes.html
+
+ The on-line release notes will be updated as needed, so you should
+ check it occasionally for the latest information.
+
+
+Bug Reports and Feedback
+
+ The Bug Parade Web Page on the Java Developer Connection(SM) web
+ site lets you search for and examine existing bug reports, submit
+ your own bug reports, and tell us which bug fixes matter most to you.
+
+ http://java.sun.com/jdc/bugParade/
+
+ To directly submit a bug or request a feature, fill out this form:
+
+ http://java.sun.com/cgi-bin/bugreport.cgi
+
+ You can also send comments directly to Java Software engineering
+ team email addresses.
+
+ http://java.sun.com/mail/
+
+
+Java 2 SDK Documentation
+
+ The on-line Java 2 SDK Documentation contains API specifications,
+ feature descriptions, developer guides, tool reference pages, demos,
+ and links to related information. It is located at
+
+ http://java.sun.com/j2se/1.4.2/docs/
+
+ The Java 2 SDK documentation is also available in a download bundle
+ which you can install locally on your machine. See the
+ Java 2 SDK download page:
+
+ http://java.sun.com/j2se/1.4.2/download.html
+
+
+Redistribution
+
+ The term "vendors" used here refers to licensees, developers,
+ and independent software vendors (ISVs) who license and
+ distribute the Java 2 Runtime Environment with their programs.
+ Vendors must follow the terms of the Java 2 SDK, Standard
+ Edition, Binary Code License agreement.
+ Required vs. Optional Files
+
+ The files that make up the Java 2 SDK, Standard Edition, are
+ divided into two categories: required and optional. Optional
+ files may be excluded from redistributions of the Java 2 SDK
+ at the vendor's discretion. The following section contains a
+ list of the files and directories that may optionally be
+ omitted from redistributions of the Java 2 SDK. All files not
+ in these lists of optional files must be included in
+ redistributions of the Java 2 SDK.
+
+ Optional Files and Directories
+
+ The following files may be optionally excluded from
+ redistributions:
+
+ jre/lib/charsets.jar
+ Character conversion classes
+ jre/lib/ext/
+ sunjce_provider.jar - the SunJCE provider for Java
+ Cryptography APIs
+ localedata.jar - contains many of the resources
+ needed for non US English locales
+ ldapsec.jar - contains security features supported
+ by the LDAP service provider
+ dnsns.jar - for the InetAddress wrapper of JNDI DNS
+ provider
+ bin/rmid and jre/bin/rmid
+ Java RMI Activation System Daemon
+ bin/rmiregistry and jre/bin/rmiregistry
+ Java Remote Object Registry
+ bin/tnameserv and jre/bin/tnameserv
+ Java IDL Name Server
+ bin/keytool and jre/bin/keytool
+ Key and Certificate Management Tool
+ bin/kinit and jre/bin/kinit
+ Used to obtain and cache Kerberos ticket-granting tickets
+ bin/klist and jre/bin/klist
+ Kerberos display entries in credentials cache and keytab
+ bin/ktab and jre/bin/ktab
+ Kerberos key table manager
+ bin/policytool and jre/bin/policytool
+ Policy File Creation and Management Tool
+ bin/orbd and jre/bin/orbd
+ Object Request Broker Daemon
+ bin/servertool and jre/bin/servertool
+ Java IDL Server Tool
+ src.zip
+ Archive of source files
+
+ In addition, the Java Web Start product may be excluded from
+ redistributions. The Java Web Start product is contained in a
+ file named javaws-1_2-solaris-sparc-i.zip,
+ javaws-1_2-solaris-i586-i.zip,
+ javaws-1_2-linux-i586-i.zip, or
+ javaws-1_2-windows-i586-i.exe, depending on the platform.
+
+
+ Unlimited Strength Java Cryptography Extension
+
+ Due to import control restrictions for some countries, the
+ Java Cryptography Extension (JCE) policy files shipped with
+ the Java 2 SDK, Standard Edition and the Java 2 Runtime
+ Environment allow strong but limited cryptography to be
+ used. These files are located at
+
+ <java-home>/lib/security/local_policy.jar
+ <java-home>/lib/security/US_export_policy.jar
+
+ where <java-home> is the jre directory of the Java 2
+ SDK or the top-level directory of the Java 2 Runtime
+ Environment.
+
+ An unlimited strength version of these files indicating
+ no restrictions on cryptographic strengths is available
+ on the Java 2 SDK web site for those living in eligible
+ countries. Those living in eligible countries may download
+ the unlimited strength version and replace the strong
+ cryptography jar files with the unlimited strength files.
+
+
+ Endorsed Standards Override Mechanism
+
+ An endorsed standard is a Java API defined through a standards
+ process other than the Java Community Process(SM) (JCP(SM)).
+ Because endorsed standards are defined outside the JCP, it is
+ anticipated that such standards will be revised between
+ releases of the Java 2 Platform. In order to take advantage of
+ new revisions to endorsed standards, developers and software
+ vendors may use the Endorsed Standards Override Mechanism to
+ provide newer versions of an endorsed standard than those
+ included in the Java 2 Platform as released by Sun Microsystems.
+
+ For more information on the Endorsed Standards Override
+ Mechanism, including the list of platform packages that it may
+ be used to override, see
+
+ http://java.sun.com/j2se/1.4.2/docs/guide/standards/
+
+ Classes in the packages listed on that web page may be replaced
+ only by classes implementing a more recent version of the API
+ as defined by the appropriate standards body.
+
+ In addition to the packages listed in the document at the above
+ URL, which are part of the Java 2 Platform, Standard Edition
+ (J2SE(TM)) specification, redistributors of Sun's J2SE
+ Reference Implementation are allowed to override classes whose
+ sole purpose is to implement the functionality provided by
+ public APIs defined in these Endorsed Standards packages.
+ Redistributors may also override classes in the org.w3c.dom.*
+ packages, or other classes whose sole purpose is to implement
+ these APIs.
+
+
+Sun Java Web Pages
+
+ For additional information, refer to these Sun Microsystems pages
+ on the World Wide Web:
+
+ http://java.sun.com/
+ The Java Software web site, with the latest information on
+ Java technology, product information, news, and features.
