IBM Developer Kit for Java

IBM Developer Kit for Java™ is optimized for use in an iSeries™ server environment. It uses the compatibility of Java programming and user interfaces, so you can develop your own applications for the iSeries server.

IBM^® Developer Kit for Java allows you to create and run Java programs on your iSeries server. IBM Developer Kit for Java is a compatible implementation of the Sun Microsystems, Inc. Java Technology, so we assume that you are familiar with their Java Development Kit (JDK) documentation. To make it easier for you to work with their information and ours, we provide links to Sun Microsystems, Inc.'s information.
