- Java(TM) 2 Runtime Environment, Standard Edition
- Version 1.4.2
-
-
- 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/1.4.2/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 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/1.4.2/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.
