README Java(TM) 2 Runtime Environment, Standard Edition Version 1.4.1 The Java(TM) 2 Runtime Environment is intended for software developers and vendors to redistribute with their applications. The Java 2 Runtime Environment contains the Java virtual machine, runtime class libraries, and Java application launcher that are necessary to run programs written in the Java programming language. It is not a development environment and does not contain development tools such as compilers or debuggers. For development tools, see the Java 2 SDK, Standard Edition. ======================================================================= Deploying Applications with the Java 2 Runtime Environment ======================================================================= When you deploy an application written in the Java programming language, your software bundle will probably consist of the following parts: Your own class, resource, and data files. A runtime environment. An installation procedure or program. You already have the first part, of course. The remainder of this document covers the other two parts. See also the Notes for Developers page on the Java Software website: http://java.sun.com/j2se/1.4.1/runtime.html ----------------------------------------------------------------------- Runtime Environment ----------------------------------------------------------------------- To run your application, a user needs the Java 2 Runtime Environment, which is freely available from Sun for application developers to redistribute. The final step in the deployment process occurs when the software is installed on individual user system. Installation consists of copying software onto the user's system, then configuring the user's system to support that software. You should ensure that your installation procedure does not overwrite existing JRE installations, as they may be required by other applications. ======================================================================= Redistribution of the Java 2 Runtime Environment ======================================================================= 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 Runtime Environment Binary Code License agreement. ----------------------------------------------------------------------- Required vs. Optional Files ----------------------------------------------------------------------- The files that make up the Java 2 Runtime Environment are divided into two categories: required and optional. Optional files may be excluded from redistributions of the Java 2 Runtime Environment at the licensee's discretion. The following section contains a list of the files and directories that may optionally be omitted from redistributions with the Java 2 Runtime Environment. All files not in these lists of optional files must be included in redistributions of the runtime environment. ----------------------------------------------------------------------- Optional Files and Directories ----------------------------------------------------------------------- The following files may be optionally excluded from redistributions: 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 Java RMI Activation System Daemon bin/rmiregistry Java Remote Object Registry bin/tnameserv Java IDL Name Server 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 Policy File Creation and Management Tool bin/orbd Object Request Broker Daemon bin/servertool Java IDL Server Tool 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. ----------------------------------------------------------------------- Redistribution of Java 2 SDK Files ----------------------------------------------------------------------- The limited set of files from the SDK listed below may be included in vendor redistributions of the Java 2 Runtime Environment. All paths are relative to the top-level directory of the SDK. - jre/lib/cmm/PYCC.pf Color profile. This file is required only if one wishes to convert between the PYCC color space and another color space. - All .ttf font files in the jre/lib/fonts directory. Note that the LucidaSansRegular.ttf font is already contained in the Java 2 Runtime Environment, so there is no need to bring that file over from the SDK. - jre/lib/audio/soundbank.gm This MIDI soundbank is present in the Java 2 SDK, but it has been removed from the Java 2 Runtime Environment in order to reduce the size of the Runtime Environment's download bundle. However, a soundbank file is necessary for MIDI playback, and therefore the SDK's soundbank.gm file may be included in redistributions of the Runtime Environment at the vendor's discretion. Several versions of enhanced MIDI soundbanks are available from the Java Sound web site: http://java.sun.com/products/java-media/sound/ These alternative soundbanks may be included in redistributions of the Java 2 Runtime Environment. - The javac bytecode compiler, consisting of the following files: bin/javac [Solaris(TM) Operating Environment and Linux] bin/sparcv9/javac [Solaris Operating Environment (SPARC(TM) Platform Edition)] bin/javac.exe [Microsoft Windows] lib/tools.jar [All platforms] - jre\bin\server\ On Microsoft Windows platforms, the Java 2 SDK includes both the Java HotSpot Server VM and Java HotSpot Client VM. However, the Java 2 Runtime Environment for Microsoft Windows platforms includes only the Java HotSpot Client VM. Those wishing to use the Java HotSpot Server VM with the Java 2 Runtime Environment may copy the SDK's jre\bin\server folder to a bin\server directory in the Java Runtime Environment. Software vendors may redistribute the Java HotSpot Server VM with their redistributions of the Java Runtime Environment. ----------------------------------------------------------------------- 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
