Java(TM) 2 Runtime Environment, Standard Edition
Version 1.3.1


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.

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:

-----------------------------------------------------------------------
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. However,
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-management profile. This file is required only if the
Java 2D API is used to perform color map conversions.

- 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 has been removed from the Java 2 Runtime Environment in
order to reduce the size of the Runtime Environment's download
bundle. MIDI soundbanks are often available in hardware form
or as part of the operating system on modern systems, and it
therefore may not be necessary to redistribute the soundbank.gm
file with the Runtime Environment. The SDK's soundbank.gm file
may, however, 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.
