Fwd: [openejb-dev] OpenEJB 3 and Cayenne JPA
FYI: below is my email exchange with David Blevins on integrating
Cayenne provider with OpenEJB by JavaOne.
Jeff, Bill - I was wondering where are we on the class enhancers and
orm.xml?

Now that I am done with the release, I have some time to work on the
JPA stuff. As it is important to have a good demo by JavaOne, I am
going to take over currently unassigned CAY-455 (mapping descriptor)
and CAY-456 (annotations loader). I won't be touching CAY-460 (class
enhancer) for now.

Bill, Jeff, let me know when you have an opportunity to work on any
of that - we can reassign these tasks again.

Its going slow...Bill and I got pulled on a project that is eating up our
