An Acronym for Java 2 Enterprise Edition. As of Java 1.5, it was renamed "Java Platform, Enterprise Edition" or "Java EE".
Java EE extends the standard Java specification with standards for developing component-based, multi-tier enterprise applications. Features include WebServices support and development tools (SDK).
Applications written in Java EE traditionally run on an application server; open source examples include Red Hat's JBoss or Sun's reference implementation, GlassFish?.
