- OVERVIEW OF JAVA RUNTIME
- =======================================================================
-
- -----------------------------------------------------------------------
- INTRODUCTION
- -----------------------------------------------------------------------
-
- This is version 1.1.1 of the Java Runtime Environment, also known as
- the Java Runtime, or JRE. The Java Runtime is the minimum standard
- Java Platform for running Java programs. It contains the Java
- Virtual Machine, Java Core Classes and supporting files.
-
- This document uses the term "vendors" to refer to licensees,
- developers, and independent software vendors (ISVs) who
- license and distribute the JRE with their Java programs.
-
- The JRE is intended for vendors who want to bundle a Java runtime
- system with their Java programs. The JRE does not have the installers
- or instructions necessary for distribution directly to end-users --
- that will come in a later version.
-
- The JRE includes all of the non-debuggable .dll or .so files plus
- the necessary classes from the JDK 1.1.1 to support a runtime-only
- program. The JRE does not include any of the development tools
- (such as appletviewer or javac) or classes that would pertain only
- to a development system.
-
- Vendors must follow the terms of the JRE Binary Code License agreement,
- which includes these terms:
-
- - Don't arbitrarily subset the JRE. You may omit only the
- files listed below as optional.
-
- - Include in your product's license the provisions called out
- in the JRE Binary Code License.
-
- The JRE is a product of Sun Microsystems, Inc.
- JavaSoft is an operating company of Sun, and develops the JRE.
-
-
- -----------------------------------------------------------------------
- REQUIRED vs. OPTIONAL FILES
- -----------------------------------------------------------------------
-
- Licensees must follow the terms of the accompanying LICENSE.
- The files that make up the JRE are divided into two categories:
- required and optional. To paraphrase that license, files that
- are marked "optional" here do not need to be included with the
- licensee's program.
-
- The term "required" means licensees who distribute the runtime
- must include those files with their program, whether or not
- their program ever uses those files. Those files are a
- required part of the Java Platform.
-
- In general, the optional files provide localization support for
- languages.
-
- The JRE includes the bin and lib directories which both must
- reside in the same directory. We call this directory <runtime-dir>.
-
- In the following lists, all paths are relative to the <runtime-dir>
- directory (which is originally "jre1.1.1").
-
- -----------------------------------------------------------------------
- WIN32 FILES
- -----------------------------------------------------------------------
-
- The following is a complete list of files included with the JRE 1.1.1
- for Win32.
-

- The following is a complete list of files included with the JRE 1.1.1
- for Solaris.
-

- libXm.so.3 is present in Solaris 2.5 and later, so is needed only if the
- ultimate target of your program is to run on Solaris 2.4 or earlier.

- BUNDLING AND RUNNING THE JAVA RUNTIME
- =======================================================================
-
- -----------------------------------------------------------------------
- BUNDLING THE JAVA RUNTIME
- -----------------------------------------------------------------------
-
- This release of the JRE does not come with an end-user installer
- program. Vendors must write their own installers.
-
- For this release, we are supporting only Java programs that are
- shipped bundled with their own copy of the Java runtime and do
- not share that runtime with other applications. At this time
- the JRE does not officially support multiple applications sharing
- a single runtime. Although in principle it is possible for
- applications to share a runtime, we will not support this
- until a future release.
-
- The JRE provides three built-in places to put classes, as shown in
- the diagram below.
-
- lib/rt.jar Java runtime core classes that Sun provides
- lib/classes.jar Vendor-defined classes in jar format
- classes/*.classes Vendor-defined individual .class files
-
-
- <runtime-dir>
- __________|________________
- | | |
- bin lib classes
- | ____|____ |
- | | *.class
- | |
- rt.jar classes.jar
-
-
- The following steps are necessary to set up the JRE 1.1.1 with an
- application:
-
- 1) It is suggested that the JRE be installed in its own subdirectory
- (referred to here as <runtime-dir>). Include all the the required
- files listed above in the bin and lib subdirectories of <runtime-dir>,
- following the same directory hierarchy and relative placement of
- files (the default classpath depends on this). The
- internationalization files marked optional can be included for
- non-native language support.
-
- 2) Place all application-specific classes either as individual .class
- files in the classes directory or zipped up in a file at
- lib/classes.jar.
-
- Both locations are automatically included in the default runtime
- class path, so they will be found even if you do not explicitly set
- the CLASSPATH environment variable. The file 'classes.jar' can be
- created using the JAR tool included with JDK 1.1 or any
- PKZIP-compatible ZIP archiving tool that supports DEFLATE
- compression, such as InfoZIP or WinZIP.
-
- 3) If native code support is required, then the native library must be
- located in LD_LIBRARY_PATH on Solaris or the executable search PATH
- on Win32. The best way to do this is to install the native libraries
- in either <runtime-dir>/lib/<sys> on Solaris or <runtime-dir>\bin
- on Win32.
-
- 4) If installing a pure Java application, then use the runtime
- executable program (<runtime-dir>\bin\java.exe on Windows or
- <runtime-dir>/bin/java on Solaris) to invoke the application's main
- class. For example:
-
- <runtime-dir>/bin/java <app-main>
-
- For applications that require the invocation API to start the Java
- runtime, then it will be necessary to write a custom C wrapper that
- uses the JNI invocation API. Examples of how to do this will be
- provided on our website.
-
-
- For more information that might be relevant to installing and running
- the JRE, refer to the JDK installation instructions:
-
- http://java.sun.com/products/jdk/1.1/installation-win32-x86.html
- http://java.sun.com/products/jdk/1.1/installation-solaris2.html
-
-
- Install Limitations ---------------------------------------------------
-
- Current limitations with the JRE 1.1.1 release that will be fixed in an
- upcoming bug-fix release:
-
- - The Win32 JRE is not immune to environment settings so that problems
- can occur when either CLASSPATH or JAVA_HOME is shared with other
- applications. For now, this can be overridden by using the '-classpath'
- switch when running 'java' or by writing a custom startup program in C
- using JNI. A future release will be free from environment variable
- settings and will use the Win32 registry instead.

- JAVA RUNTIME EXAMPLE
- -----------------------------------------------------------------------
-
- The following web page has a Hello World example that you can download
- demonstrating how to create a simple Java application that runs on,
- and is bundled with, the Java Runtime Environment.
- The bundle you download includes the JRE.
-
- http://java.sun.com/products/jdk/1.1/jre/example/
-
- This example shows how to make a simple, seamless transition
- from developing an application with the JDK, to deploying it with
- the more-lightweight JRE.
-
-
- -----------------------------------------------------------------------
- RUNTIME DOCUMENTATION
- -----------------------------------------------------------------------
-
- Runtime documentation is any documentation that an end-user might
- need after they have installed a Java program that runs on the JRE.
-
- We supply the following runtime documentation:
-
- - Each property file contains comments that describe what the
- file is useful for and how to modify it.
-
- - awt.properties file - KeyEvent uses it to print out properties of
- key events, usually for debugging purposes. This might be used
- by a GUI debugger that needs to print out events.
-
- - fontprop.html file has a web page describing how to add
- fonts to the runtime. This document is part of the
- JDK documentation, and is located both in the JDK documentation
- download bundle and at the JavaSoft website:
-
- http://java.sun.com/products/jdk/1.1/docs/guide/intl/fontprop.html
