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. Depending on the platform, the Java Web Start
product is contained in a file named as follows. The actual
product version number would replace the <version number> notation.

javaws-<version number>-solaris-sparc-i.zip
javaws-<version number>-solaris-i586-i.zip
javaws-<version number>-linux-i586-i.zip
javaws-<version number>-windows-i586-i.exe

-----------------------------------------------------------------------
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 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/1.4.1/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.
