Java Enterprise Edition 5

Perhaps the biggest new feature in WTP 2.0 is support for Java EE 5, which includes JSF, JPA, and revisions of many existing specifications, including JAX-WS for Web services. JAX-WS will include support for SOAP 1.2. All of the WTP J2EE models will be upgraded to the new specification levels.

The most exciting aspect of Java EE 5 for programmers is its simplification of the programming model and its use of attribute-based programming. Code attributes were introduced into the Java programming language by JSR 175. Attributes for Web services were defined in JSR 181. Both JSR 175 and 181 are part of Java EE 5. In addition, code attributes for EJBs and JPA are defined in JSR 220, which is also part of Java EE 5.
