### Product Information

IBM is a key partner with Sun Microsystems and other industry leaders in developing and promoting Java technology. IBM OS/2 Warp Developer Kit, Java(TM) 2 Technology Edition brings Java's write once, run everywhere cross-platform capability to IBM's award-winning OS/2 Warp operating system.

IBM OS/2 Warp Developer Kit, Java(TM) 2 Technology Edition consists of the following components:

- Runtime
- Toolkit
- Samples
- ICAT Debugger for OS/2 Java

### Runtime Component

The Runtime component can be installed by itself on either a FAT, HPFS, or JFS formatted drive and provides the ability to run Java applications and applets directly from an OS/2 session command line. The Runtime component includes a just-in-time (JIT) compiler that generates machine code for frequently used byte code sequences in a Java application or applet on-the-fly during execution.

### Toolkit Component

If you want to develop Java applications and applets of your own, then install the Toolkit component on an HPFS or JFS formatted drive. The Toolkit requires that the Runtime be installed at the same time and on on the same drive. The Toolkit helps you:

- Develop applets that conform to the 100% Pure Java(TM) specification
- Develop stand-alone Java applications

### Samples Component

With Java, there is no need to start from scratch on your programming efforts. Install the Samples component and you can run and later modify code from existing, working Java applications and applets.

### ICAT Debugger for Java OS/2 Component

The ICAT (Interactive Code Analysis Tool) Debugger for Java OS/2 is new with IBM OS/2 Warp Developer Kit, Java(TM) 2 Technology Edition. The ICAT Debugger is a powerful source-level debugger to assist you in developing your Java applications.

### Configuring your Default JVMs

Some applications require Java 1.1.x as the system default JVM. These applications may fail if Java 1.3.1 is installed as the system default JVM. Please refer to the Installation and Configuration Guide for details on how to use both Java 1.1.x and Java 1.3.1. Return to Component Selection.
