The JDK contains the software and tools that developers need to compile, debug, and run applets and applications written using the Java programming language. The JDK software and documentation, typically included with each new release of an operating system, are available for download at the vendor's Web site. You need a JDK if you intend to develop Java stored procedures and triggers with the database, or if you intend to create Java proxies with the Progress® Open Client Toolkit.
