README Java(TM) 2 Runtime Environment, Standard Edition Version 1.3.1 ********************************************************************* * Notice of New Redistribution Options * * * * Beginning October 17, 2001, it is permissable to redistribute * * the "javac" compiler with the Java 2 Runtime Environment (JRE). * * See the Sun Binary Code License and this README for terms * * and conditions. Items that have been added to the section * * in this README entitled "Redistribution of Java 2 SDK files" * * are: * * * * bin/javac.exe (Microsoft Windows) * * bin/javac and bin/i386/native_threads/javac (Linux and Solaris IA) * * bin/javac and bin/sparc/native_threads/javac (Solaris SPARC) * * lib/tools.jar (all platforms) * * * * These files include the Java 2 SDK tools classes, including * * the classes for the "javac" compiler. * * * * Additionally, on Microsoft Windows platforms it is now * * permissible to redistribute the Java HotSpot Server VM (also * * known as "C2") with the Microsoft Windows version of the * * JRE. (C2 is already included with the JREs for Linux and the * * Solaris(TM) operating environment.) Items that have been added * * to the section on "Redistribution of Java 2 SDK files" are: * * * * jre/bin/server/jvm.dll * * jre/bin/server/Xusage.txt * * * ********************************************************************** The Java 2 Runtime Environment is intended for software developers and vendors to redistribute with their applications. The Java(TM) 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 progamming 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. ======================================================================= Installation Instructions and System Requirements ======================================================================= For installation instructions and system requirements for this release, see http://java.sun.com/j2se/1.3/install.html ======================================================================= Deploying Applications with the Java 2 Runtime Environment ======================================================================= A Java-language application, unlike an applet, cannot rely on a web browser for installation and runtime services. 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/1.3/runtime.html ----------------------------------------------------------------------- Runtime Environment ----------------------------------------------------------------------- To run your application, a user needs a Java virtual machine, the Java platform core classes, and various support programs and files. This collection of software is known as a runtime environment. The Java 2 SDK software can serve as a runtime environment. However, you probably can't assume your users have the Java 2 SDK installed, and your Java 2 SDK license doesn't allow you to redistribute SDK files. To solve this problem, Sun provides the Java 2 Runtime Environment as a free, redistributable runtime environment. (The Java 2 runtime environment should not be confused with the Java 2 SDK's own internal, non-redistributable version of the runtime environment housed in the SDK's 'jre' directory.) 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. This step includes installing and configuring the runtime environment. If you use the Java 2 Runtime Environment, you must make sure that your installation procedure never overwrites an existing installation, unless the existing runtime environment is an older version. ======================================================================= 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 Binary Code License agreement which include, among others: - Arbitrary subsetting of the Java 2 Runtime Environment is not allowed. See the section below entitled "Required vs. Optional Files" for those files that may be optionally omitted from redistributions of the runtime environment. - You must include in your product's license the provisions called out in the Binary Code license. ----------------------------------------------------------------------- Required vs. Optional Files ----------------------------------------------------------------------- Licensees must follow the terms of the Java 2 Runtime Environment license. 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/i18n.jar Character conversion classes and all other locale support lib/ext/ Directory containing extension jar files 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/policytool Policy File Creation and Management Tool ----------------------------------------------------------------------- Redistribution of Java 2 SDK Files ----------------------------------------------------------------------- The Java 2 SDK, Standard Edition, may not be redistributed.
