Politically Charged EJB Decision Hands a Victory to JBoss
The EJB expert group's decision to use Hibernate as the persistence mechanism in EJB 3.0 gives JBoss all the power. David Jordan, a member of the JDO expert group, explains why the JDO community is not just disappointed—but concerned—about a power shift in the app server market.

he EJB 3.0 expert group seems to have handed JBoss the EJB application server market on a silver platter. Several weeks ago at TheServerSide Java Symposium in Las Vegas the EJB expert group announced its decision to shelve the current entity bean architecture and focus on the lightweight persistence of Plain Old Java Objects (POJOs). Specifically, it decided to use Hibernate as the persistence mechanism in EJB 3.0. Hibernate is an open source object/relational mapping solution that joined the JBoss Group last year.
The EJB 3.0 expert group's decision to adopt Hibernate has given JBoss a lot of influence in the EJB app server market, and they are now leveraging it to gain an advantage. JBoss CEO and Founder Marc Fleury emphasized at a recent Triangle Java User's Group meeting in Research Triangle Park, N.C. that "Hibernate is EJB 3.0". He made a very compelling case for using Hibernate now as a means to gain early access to EJB 3.0. In addition, he provided convincing reasons why you should use JBoss now as the preferred EJB 3.0 application server. His take-home message was clear: to minimize the costs of migrating to EJB 3.0, use Hibernate and JBoss now. If I were an EJB community member who planned to eventually migrate to an EJB 3.0 implementation (which I'm not), he would have convinced me.
