- Java(TM) 2 Runtime Environment, Standard Edition
- Version 1.3.0_01
-
-
- 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. If you need development tools,
- use the Java 2 SDK (Software Development Kit) rather than the
- Java 2 Runtime Environment.
-
- The Java 2 Runtime Environment includes the Java Plug-in product
- which enables support for the Java 2 platform on recent releases of
- Netscape Navigator and Microsoft Internet Explorer. For more
- information, see the Plug-in web page at
- http://java.sun.com/products/plugin/ .

- =======================================================================
- 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:
-
- http://java.sun.com/j2se/1.3/runtime.html
-
- -----------------------------------------------------------------------
- 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 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.
-
- The Win32 version of the Java 2 Runtime Environment is distributed as a
- self-installing executable. A simple way to redistribute the Java 2
- Runtime Environment is to include this executable in your software
- bundle. You can then have your installation program run the executable
- to install the Java 2 Runtime Environment, or simply instruct the user
- to install the Java 2 Runtime Environment before installing the rest of
- your bundle. In this installation model, the end-user will have a
- "public" copy of the Java 2 Runtime Environment just as if it had been
- downloaded from Sun's website and installed separately.
-
- The Runtime Environment's installation program records program
- information in the Windows Registry. This registry information
- includes the software version, which you should compare with the Java 2
- Runtime Environment version in your software bundle. For more information,
- refer to the Notes for Developers on the Java Software web site:
-
- http://java.sun.com/j2se/1.3/runtime.html
-
- Another approach is to install the Java 2 Runtime Environment on your
- own system, then copy the files you need into your application's own
- installation set for redistribution. If you choose this approach,
- you must include all files except those described as "optional" in the
- "Redistrubition of the Java 2 runtime environment" section of this
- README. The Java 2 Runtime Environment software can only be
- redistributed if all "required" files are included. See the license
- file for specifics.
-
- If you use this approach, do not try to emulate the installation steps
- performed by the Java 2 Runtime Environment installer. You might "break"
- an existing runtime environment installation by missing a new or
- undocumented installation step. Instead, you should include the Java 2
- Runtime Environment files in your own application directory. In
- effect, your application has its own "private" copy of the Java 2
- Runtime Environment.
-
- The Java 2 Runtime Environment includes Java Plug-in software,
- which enables Netscape Navigator and Microsoft Internet Explorer to
- support the Java 2 platform. To develop applets that use Java Plug-in
- software, see the Java Plug-in product page on the Java Software web
- site:
-
- http://java.sun.com/products/plugin/
-

- -----------------------------------------------------------------------
- Winsock Deployment
- -----------------------------------------------------------------------
-
- If your application uses the networking classes, it may not run
- reliably under Winsock 1.1. If your networking application must support
- Windows 95, which includes Winsock 1.1, you will want to include a
- Winsock 2.0 install in your installation procedure. (Windows NT 4.0 and
- Windows 98 include Winsock 2.0.) You can download the Winsock 2.0
- from this address:
-
- http://www.microsoft.com/windows95/downloads/contents/wuadmintools/s_wunetworkingtools/w95sockets2/
-
- The following URL contains information about how to determine if
- the Winsock 2.0 components are installed on a Windows 95 platform:

- =======================================================================
- 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 sections contain lists of the files that may be
- optionally 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.
-
- The Java 2 Runtime Environment includes the bin and lib directories
- which both must reside in the same directory, called <runtime-dir> in
- the lists below. All paths are relative to the <runtime-dir> directory.
-
- Note that the native code C runtime library, msvcrt.dll, is located
- in the Windows system directory. This file should be included in
- redistributions of the Win32 version of the Java 2 Runtime Environment.
-
- -----------------------------------------------------------------------
- Optional Files and Directories
- -----------------------------------------------------------------------
- All font properties files in the lib directory other than the default
- lib\font.properties file are optional, and vendors may choose not to
- include them in redistributions of the Java 2 Runtime Environment. In
- addition, the following may be optionally excluded from
- redistributions:
-
- bin\beans.ocx
- Plugin ActiveX control
- lib\jaws.jar
- Plugin classes
- lib\i18n.jar
- Character conversion classes and all other locale support
- lib\ext\
- Directory containing extension jar files
- bin\rmid.exe
- Java RMI Activation System Daemon
- bin\rmiregistry.exe
- Java Remote Object Registry
- bin\tnameserv.exe
- Java IDL Name Server
- bin\keytool.exe
- Key and Certificate Management Tool
- bin\policytool.exe
- 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 Win32 version of 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 is a MIDI soundbank used by the software MIDI
- synthesizer. MIDI synthesis is commmonly available in hardware
- or as part of the operating system on modern Win32 systems.
- On these systems, MIDI synthesis may be supported through
- these native services rather than through use of the software
- synthesizer, and the soundbank.gm file may not be required.
- To reduce the size of the Runtime Environment's download
- bundle, the soundbank has been removed from the Java 2 Runtime
- Environment. However, a soundbank file may be included in
- redistributions of the Runtime Environment at the vendor's
- discretion. A minimal soundbank file (soundbank.gm) is
- included with the SDK. This minimal soundbank and a selection
- of enhanced MIDI soundbanks are available from the Java Sound
- web site: http://java.sun.com/products/java-media/sound/
- Any of these soundbanks may be included in redistributions
- of the Java 2 Runtime Environment. These soundbanks also may
- be installed to enable software MIDI synthesis in distributions
- which did not include a soundbank, or to upgrade the quality of
- software MIDI synthesis in distributions which included the
- minimal soundbank file.
