Java EE Technologies At a Glance

Java Platform, Enterprise Edition (Java EE) is a set of coordinated technologies and practices that enable solutions for developing, deploying, and managing multi-tier, server-centric applications. Building on Java Platform, Standard Edition (Java SE), Java EE adds the capabilities that provide a complete, stable, secure, and fast Java platform for the enterprise. Java EE significantly reduces the cost and complexity of developing and deploying multi-tier solutions, resulting in services that can be rapidly deployed and easily enhanced.

Want to learn more about the technologies that comprise the Java EE 5 platform? Here's a list of the technologies, and their specifications, for Java EE 5 -- starting with the umbrella Java EE 5 specification.

Java EE 5

Java Platform, Enterprise Edition 5 (Java EE 5) (JSR 244)

Web Services Technologies

Implementing Enterprise Web Services (JSR 109)
Java API for XML-Based Web Services (JAX-WS) 2.0 (JSR 224)

Note that this and future versions of the Java platform have simplified names. The "2" is dropped from the name, as well as the "dot number." So the next version of the Java platform for the enterprise is Java Platform, Enterprise Edition 5 (Java EE 5). Any updates to future Java platforms will simply be noted as "updates," rather than adding a "dot number" at the end of the platform name.
