Thank you for downloading this release of the Java(TM) 2 SDK, Standard Edition. The Java 2 SDK is a development environment for building applications, applets, and components that can be deployed on the Java platform.

The Java 2 SDK software includes tools useful for developing and testing programs written in the Java programming language and running on the Java platform. These tools are designed to be used from the command line. Except for appletviewer, these tools do not provide a graphical user interface.

The Java 2 SDK comes with the Java Plug-in product. You can use the Java Plug-in product to enable the Internet Explorer and Netscape Navigator browsers to run applets based on the Java 2 Platform. For more information about the Java Plug-in product, see the section titled "Java 2 Runtime Environment and Java Plug-in" in the README.html file.


The complete Java 2 SDK is composed of the SDK Software plus the SDK Documentation, each of which is separately downloadable. Installation instructions are maintained on the web site:

The version 1.3 of the Java 2 SDK offers significant improvements in functionality and performance over previous versions. See:

  • Summary of New Features - New features in original 1.3.0 release of the Java 2 SDK.

  • Guide to Features - Complete list of all features.

This release, J2SE 1.3.0_01, is the first update release of J2SE 1.3.0. J2SE 1.3.0_01 contains new Java Plug-in enhancements, including support for the Netscape Communicator 6 browser. In addition, J2SE 1.3.0_01 contains fixes for bugs that have been identified in the original J2SE 1.3.0 release. See the Release Notes on the Java Software web site for details about the changes in J2SE 1.3.0_01.

See also the documentation for the new Java Plug-in enhancements.


A demo directory is included in this software bundle with a variety of applets, Swing applications, and other examples for you to try out. The demos come with complete source code.

Java 2 SDK Documentation

This section describes the documentation provided with the original J2SE 1.3.0 release. That documentation is applicable to J2SE 1.3.0_01 as well. For new features and bug fixes in J2SE 1.3.0_01, see the online release notes.

The on-line J2SE Documentation contains API specifications, developer guides, tool reference pages, demos, and links to related information. It is located at

The Java 2 SDK documentation is also available in a download bundle which you can install locally with your Java 2 SDK software. See the download page:

System Requirements

Windows 95, Windows 98, Windows NT 4.0, or Windows 2000 operating systems running on Intel hardware. A Pentium 166 MHz or faster processor.

At least 32 megabytes of physical RAM is required to run GUI applications. Forty-eight megabytes is recommended for applets running within a browser using the Java Plug-in product. Running with less memory may cause disk swapping which has a severe effect on performance. Very large programs may require more RAM for adequate performance.

You should have 65 megabytes of free disk space before attempting to install the Java 2 SDK software. If you also install the separate documentation download bundle, you need an additional 120 megabytes of free disk space.
