Migrating to Java Platform, Enterprise Edition (Java EE) 6

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.

About this task

The product supports the following specification and application programming interface (API) levels that are new in 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.

Procedure

  1. Decide whether to take advantage of new Java EE 6 capabilities in your applications.

    The Version 8.5 product supports applications written to Java EE 6 and supports portable applications written to previous Java EE versions, specifically Java EE 5, Java 2 Platform, Enterprise Edition (J2EE) 1.4, and J2EE 1.3. If you decide not to use new Java EE 6 capabilities, your portable applications will continue to work without change and with identical behavior on the current version of the platform.

  2. If you select to use new Java EE 6 capabilities in your applications, change the applications as needed to conform to the specifications.
  3. Deploy your applications.

    Deploy applications that use new Java EE 6 capabilities only to Version 8 deployment targets. You can deploy applications written to previous specifications to Version 8 deployment targets or to Version 6.x or 7.x deployment targets.

What to do next

Test the deployed applications to ensure that the applications behave as expected. Update the applications as needed.
