Java EE 5 App Server Race Begins


By Alex Handy
May 15, 2006 — 
Now that the Java Platform, Enterprise Edition 5 specification has wound its way through the Java Community Process, the application server makers are preparing to update their wares with the latest Java bells and whistles.

With new support for annotations, the Java API for XML Web Services (JaxWS) and Enterprise JavaBeans 3.0 persistence, Java EE 5 promises to ease the development process for corporate coders.

But without full-scale Java EE 5-compliant application servers available, many will have to wait until next year to wade into this new revision of the language. (The Java EE 5 spec, also known as JSR 244, was approved by the Java Community Process on May 1.)

John Rymer, vice president of the application development and infrastructure group at Forrester Research, said that the first available Java EE 5 application server, the open-source Glassfish project, is not attracting much attention from the enterprise crowds. According to Rymer, most companies are waiting for the more robust offerings from BEA, IBM, JBoss and Oracle.

Rymer said that his clients are mainly interested in how application servers handle EJB 3.0. Blake Connell, director of WebLogic Server product marketing at BEA, agreed, citing the company’s acquisition last fall of Solarmetric, which develops the Kodo implementation of the Java Persistence API (JPA). BEA’s Java EE 5-compliant app server should be ready by the end of 2006, according to Dave Douglas, BEA’s chief architect of WebLogic.

Mark Heid, program director for IBM’s WebSphere Application Server, said that EJB 3.0 is high on his company’s priority list as well. “It offers a persistence layer for accessing data store back ends that hasn’t been available thus far,” said Heid, adding that the company would “be delivering parts of Java EE 5 over the next 12 months. They’ll be delivered as additions to version 6.1.”

Sun Microsystems’ Java EE 5-compliant application server is available as a beta, under the name Application Server PE 9. The server is based on Glassfish, the Sun-led open-source Java EE 5 server. Oracle has also been a member of this project, contributing its EJB 3.0 implementation.

Ken Drachnik, group product manager of the application platform group at Sun, said the server should be released this summer.

Shaun Connolly, vice president of product management at JBoss, said that version 4.0.4 supports EJB 3.0. “Our app server 5.0, which will basically sweep up all that stuff and round out some of the other specs, will likely be hitting the community release in the summer, and then it will finalize after that toward the end of the summer,” said Connolly.

Another company that’s already implemented the new persistence standards of EJB 3.0 is Oracle. “We’ve seen them grow dramatically during the last two or three years, both in product development and in the marketplace,” said Rymer, who has been briefed by each of the major app server makers. “I have not seen the Oracle app server being used at the same scale as I’ve seen WebSphere and WebLogic being used,” said Rymer.

Mike Lehmann, director of product management for Oracle Application Server, Java EE and Web services, said his team is “focusing very heavily on EJB 3.0 and JavaServer Faces as key componentry that will be Java EE 5.0 ready in the next release of Oracle Application Server.” Lehmann did not estimate a release date, however.
