Since Hibernate joined the JBoss group and they are known to be looking for a JDO solution, will a JDO interface eventually be supported as part of the Hibernate project? Jakarta OJB currently supports JDO through the Sun RI. Is this possible for Hibernate as well?

Hibernate will not support JDO 1. It will definitely not be available as a plugin for the toy JDO reference implementation.

Hibernate is intended as a production-ready solution for serious applications.

Do you really believe that JDO can't become a "production-ready solution for serious applications"??

I really believe that JDO 1 is not. I am participating in the JDO2 effort in the hope that a future iteration of the spec will change this.

I mean c'mon guys, be serious! I cannot even do a wildcard search in JDOQL!



requires vendor extensions in JDO.

(JDOQL only supports startsWith() and endsWith())

I'm not going to waste time with this until the spec is sufficiently mature. Meanwhile we are the de facto standard.

OK, so it might be reasonable to assume that when there is a JDO 2 that is sufficiently mature, then there will be a migration path for Hibernate developers to move over to JDO and still reuse the mappings that they invested in for Hibernate?

I am serious about a migration path here because I truly believe that JDO (or something very similar) will become the de facto vendor independant standard, much like JDBC. After all, while Hibernate may be very good at what it does, I don't think anybody wants to be tied to any single implementation for persistence. After all, things are moving so fast and JDBC has worked out very well for vendor independance, with JDBC drivers getting better all the time.

There is already debate on theserverside.com forums about using Hibernate as the basis for a JDO/R standard.

My guess is that there is something being baked in the JBoss Group right now but it is too early to make it public.
