Introduction

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 Win32 version of the Java 2 SDK comes with the Java Plug-in. You can use the Java Plug-in 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, including how to obtain a Solaris version, see the section Java 2 Runtime Environment and Java Plug-in in the README.html file.

Installation

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

For the Win32 Installation Instructions, go to http://java.sun.com/products/jdk/1.2/install-windows.html
For the Solaris Installation Instructions, go to http://java.sun.com/products/jdk/1.2/install-solaris.html

Features

The Java 2 SDK offers significant improvements in functionality, performance, security and global support over previous versions of the Java platform. See:

Demos

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

Java 2 SDK Documentation

The online Java 2 SDK Documentation contains API specifications, developer guides, tool reference pages, demos, and links to related information. The online documentation is available at

http://java.sun.com/products/jdk/1.2/docs/

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

System Requirements

The Java 2 SDK software is available on three platforms:

Win32 Version for Windows 95, Windows 98 and Windows NT 4.0 on Intel hardware. A 486/DX or faster processor. 32 megabytes RAM minimum, 48 megabytes RAM recommended.
Solaris/SPARC Version. Only Solaris versions 2.5.1, 2.6 and 7 (also known as 2.7) are supported. 32 megabytes RAM minimum, 48 megabytes RAM recommended.
Solaris/Intel Version. Only Solaris versions 2.5.1, 2.6 and 7 (also known as 2.7) are supported. A 486/DX or faster processor. 32 megabytes RAM minimum, 48 megabytes RAM recommended.

On all systems 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 90 megabytes of free disk space.

Solaris users will want to check the list of recommended and required patches. http://java.sun.com/products/jdk/1.2/install-solaris-patches.html

It is strongly recommended that Solaris 2.6 users load the SUNWi1of package for optional Latin-1 fonts. This package is in the "Entire Distribution" Cluster, available on the Solaris software installation CD-ROM. SUNWi1of contains English Monotype TrueType fonts specified in the font properties files. Without this package, fonts will default to the LucidaSans font for off-screen text and to Type1 font for text in components.
