README Java(TM) Platform, Standard Edition Runtime Environment Version 6 The Java(TM) Platform, Standard Edition Runtime Environment (JRE(TM)), excluding the JavaFX(TM) runtime, is intended for software developers and vendors to redistribute with their applications. The Java SE 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 SE Development Kit (JDK(TM)). The JRE installation triggers the download of the JavaFX runtime. The JavaFX runtime is also available separately, and is not part of the JRE. For information on JavaFX, and how to make changes, go to: http://java.com/javafx ======================================================================= Deploying Applications with the Java SE 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. The Java SE 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/javase/6/webnotes/runtime.html ----------------------------------------------------------------------- Java Platform, Standard Edition Runtime Environment (JRE) ----------------------------------------------------------------------- To run your application, a user needs the Java SE Runtime Environment, which is freely available from Oracle. Or, you can redistribute the Java SE Runtime Environment for free with your application, according to the terms of the Java SE Platform Runtime Environment's license. The JavaFX runtime is only required to run applications written in the JavaFX scripting language; it is freely available from Oracle, and must not be redistributed with your application. The final step in the deployment process occurs when the software is installed on an individual user's 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 SE Runtime Environment (JRE) ======================================================================= -------------------------------------------------------- NOTE - The license for this software does not allow the redistribution of beta and other pre-release versions. -------------------------------------------------------- Subject to the terms and conditions of the Software License Agreement and the obligations, restrictions, and exceptions set forth below, You may reproduce and distribute the Software (and also portions of Software identified below as Redistributable), provided that: (a) you distribute the Software complete and unmodified and only bundled as part of your applets and applications ("Programs"), (b) your Programs add significant and primary functionality to the Software, (c) your Programs are only intended to run on Java-enabled general purpose desktop computers and servers, (d) you distribute Software for the sole purpose of running your Programs, (e) you do not distribute additional software intended to replace any component(s) of the Software, (f) you do not remove or alter any proprietary legends or notices contained in or on the Software, (g) you only distribute the Software subject to a license agreement that protects Oracle's interests consistent with the terms contained in this Agreement, and (h) you agree to defend and indemnify Oracle and its licensors from and against any damages, costs, liabilities, settlement amounts and/or expenses (including attorneys' fees) incurred in connection with any claim, lawsuit or action by any third party that arises or results from the use or distribution of any and all Programs and/or Software. The term "vendors" used here refers to licensees, developers, and independent software vendors (ISVs) who license and distribute the Java SE Runtime Environment with their programs. Vendors must follow the terms of the Java SE Runtime Environment Binary Code License agreement. ----------------------------------------------------------------------- Required vs. Optional Files ----------------------------------------------------------------------- The files that make up the Java SE Runtime Environment are divided into two categories: required and optional. Optional files may be excluded from redistributions of the Java SE Runtime Environment at the vendor's discretion. The following section contains a list of the files and directories that may optionally be omitted from redistributions with the Java SE 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. These files are located in the jre1.6.0_<version> directory, where <version> is the update version number. Solaris and Linux filenames and separators are shown. Windows executables have the ".exe" suffix. Corresponding files with _g in the name can also be excluded. The corresponding man pages should be excluded for any excluded executables (with paths listed below beginning with bin/ , for the Solaris(TM) Operating System and Linux). lib/charsets.jar Character conversion classes 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 Used to obtain and cache Kerberos ticket-granting tickets bin/klist Kerberos display entries in credentials cache and keytab 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 bin/javaws, lib/javaws/ and lib/javaws.jar Java Web Start When redistributing the JRE on Microsoft Windows as a private application runtime (not accessible by other applications) with a custom launcher, the following files are also optional. These are libraries and executables that are used for Java support in Internet Explorer and Mozilla family browsers; these files are not needed in a private JRE redistribution. bin\java.exe bin\javaw.exe bin\javaws.exe bin\javacpl.exe bin\jucheck.exe bin\jusched.exe bin\wsdetect.dll bin\NPJPI*.dll (The filename changes in every release) bin\NPJava11.dll bin\NPJava12.dll bin\NPJava
