A Java package is a technique for organizing Java classes into folders or Java packages can be stored in compressed files called JAR files. JAR files allow packages or classes to be organized by application or category, distributed and deployed (installed) for execution. One or more Jar files maybe further combined or compressed into a ZIP file to enable easier installation on Windows-based platforms. JAR contain META data that documents the contents of Java Packages and application security descriptors. Java application security may be enforced at the class, JAR, or server level.

The following platforms will contain an SDK and JRE which have been system tested to ensure that all packages are compatible.
