According to Bill Burke's message on the jboss-user mailing list,
JBossDO has been retired in favor of Hibernate

For those that don't know... Gavin King (Lead Developer of Hibernate) nows works for the JBoss Group. Therefore, JBoss users can expect some nice Hibernate integration coming out of Mark's camp in the future.
Furthermore, Gavin is a member of the JDO 2.0 Expert Group and therefore Hibernate will likely implement JDO 2.0 whenever that gets finished. Don't expect this for at least another couple of years.
One more thing... Hibernate rocks!

I'm interested in Hibernate and familiar with JBoss's move to Hibernate and thanks for the info on Hibernate implementation of JDO 2.0 in a couple of years. Some interesting applications should come out of that work!!
What about Hibernate and WebSphere 4.01? I have a client working in that arena and was wondering if anyone has tried it out there.
Would anyone recommend ramping up on Hibernate in an 8 week implementation instead of using straight JDBC. Both alternatives would utilize EJB Stateless SEssion beans (delegating and facades patterns being implemented on top of ORM).

If you are using Remote EJBs, you will not be able to send the Hibernate generate beans over the network. Since the beans are modified at runtime, any client that used them would also need the hibernate jar file, and then they would still not be able to use certain methods due to lazy init. If the client tried to access a Collection that wasn't initialized, the Hibernate modified bean would try to go to the persistent store, which the client knows nothing of.
You can still use Hibernate on the server side, you just have to create Data Transfer Objects to handle the trasfer of data.
