WebLogic Server 10 Goes Beyond Java EE 5


BEA’s enhancements deliver annotations; WebLogic Workshop now based on Eclipse

By David Worthington
May 1, 2007 —  (Page 1 of 2)
When it released WebLogic Server 10 on March 30, BEA Systems made no bones about it; the company considers this to be a significant release. First and foremost, BEA implemented Java EE 5 in WebLogic with its own enhancements for developers. In addition, WebLogic now supports a wider set of specifications for Web services.

Blake Connell, director of WebLogic Server product marketing at BEA, said that the primary focus for WebLogic 10 was to implement Java EE 5. BEA introduced annotations that enhance the implementation by making deployment descriptor files optional.

Annotations eliminate the need to support XML files to describe these transactions, but WebLogic still supports its legacy method, said Connell. BEA open-sourced its JPA implementation as an Apache Project called OpenJPA.

The JavaBeans 3.0 platform and IDE come with the territory. Connell pointed to the Java Persistence API (JPA), a component of Java EE 5 and EJB, as a key pillar of the release. JPA manages transactions for information storage and retrieval within data stores.

MORE CHOICE
BEA has shed some of its proprietary ways: WebLogic Workshop is now Eclipse-based, and as such, it can merge into developers’ existing Eclipse environments. This provides developers with a single Eclipse instance that has access to BEA’s Web services technology, said Connell.

Also, the Spring and Apache Struts frameworks can now be used to build applications for WebLogic.

The Spring framework is a system for assembling components using configuration files. BEA collaborated with Interface21, the group behind the Spring framework, to mix Spring-style development with Java EE 5 development. Apache’s Struts framework is used to build Servlet/JSP based Web applications and integrates with WebLogic. Connell noted that BEA wants to extend support beyond its native framework so that developers can choose which development makes sense for them.

According to Connell, BEA has adopted JAX-WS (Java API for XML-based Web Services) 2.0 as the centerpiece for building Web services going forward, for WebLogic 10 and beyond. JAX-WS can leverage BEA’s annotations style.
