README Java(TM) 2 SDK, Standard Edition Version 1.4.2 Beta For a more extensive HTML version of this file, see README.html. Contents * Introduction * Release Notes * Bug Reports and Feedback * Java 2 SDK Documentation * Redistribution * Web Pages 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 /lib/security/local_policy.jar /lib/security/US_export_policy.jar where 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.
