JEE7: Looking ahead to a new era

With the release of Java EE 7 scheduled for the second half of 2012, projected JSRs are all up and running. The Java EE 7 release, which will reflect the evolving needs of the industry as it moves into the cloud, is date driven: anything not ready will be deferred to Java EE 8.

Here is an update and summary of the key features of different specifications in the Java EE 7 platform.

1.     Java EE 7 Specification (JSR-342)
