Version 8.5 of the product supports the Java Platform, Enterprise Edition (Java EE) 6 specification. Your new and existing enterprise applications can take advantage of the capabilities added by Java EE 6.
The new specifications add several capabilities to benefit application developers, such as profiles that provide common features among applications.
Further, several specifications expand the use of annotations to more module types. Java language annotations simplify development of Java EE applications. By using annotations, many applications can avoid the need for deployment descriptors. In Version 7, the product supported annotations for EJB 3.0 and Web 2.5 modules . In Version 8, the product supports annotations for additional modules types, such as resource adapters or RAR files, as well as continues to support the use of deployment descriptors.
The general steps for migrating your enterprise applications follow.
