Java EE 5 specifications in PFD

The Java EE 5 platform is described through a platform specification, a test suite (CTS), and a reference implementation. The reference implementation uses the code base developed by the GlassFish Community. The platform specification refers to a Java SE platform spec (J2SE 5.0, aka. Tiger), a collection of additional specs, and additional constraints. All these specifications are defined through the JCP and are now in the Proposed Final Draft stage. This means that the corresponding Expert Groups believe the specifications are essentially all done and the implementations and test suites are being written against these specs.

In a day or two there should be a page for Java EE 5 at http://java.sun.com/javaee/5/javatech.html. In the meantime, here is a list of the specs in PFD (the full list is at JCP.org):

• JSR 244 - Java Platform, Enterprise Edition 5 (Java EE 5) Specification - spec.
• JSR 222 - Java Architecture for XML Binding (JAXB) 2.0 - spec.
• JSR 224 - Java API for XML-Based Web Services (JAX-WS) 2.0 - spec.
• JSR 245 - JavaServer Pages 2.1 - spec.
• JSR 250 - Common Annotations for the Java Platform - spec.
• JSR 252 - JavaServer Faces 1.2 - spec.

There are a number of other specifications in Java EE 5, and the java.sun.com page lists them all. Of those, the most significant ones new specs that are not yet in PFD are Java Persistence and EJB 3.0, but they are very close. The latest released specs are the Public Drafts. Of the maintenance releases, probably the most significant ones are those for JSR 181: Web Service Metadata for the Java Platform and JSR 173: Streaming API for XML.

The implementation at Java.Net is tracking the specifications quite closely. There will a beta early next year, but if you want to kick the tires before then, please refer to the downloads page.
