Hi David,
Let's do it!
Currently a JPA EntityManager is a thin wrapper around Cayenne so it
allows to use the JPA API, but underneath it only supports Cayenne
mapping. EJB QL queries are yet unsupported. Jeff Genender and Bill
Dudney are looking at class enhancers, annotations and the mapping.
I'll check on cayenne-dev list where we stand on that.
As far as container integration, we can start right away, as provider
part is there. Here is provider M2 project info:

I guess once we nail down the integration part, we can continue to
work in parallel and get in as many features as possible.

Hey Andrus,
What's the status of the Cayenne JPA stuff? Are there any parts
implementing JPA interfaces which are more or less usable at the
moment?
I'm completely insane of course, but I think if i work all night
and day for the next few weeks I can have something for people to
play around with by JavaOne. You up for the challenge?
At the moment I'm poking at the start of some deployment code and
it's going quite well. By the weekend we should see some magic
there and I'll be looking line up some more integration stuff, then
I'll be working more on the 2.x container integration. So there is
like a week or two gap till I'd be looking for some JPA
functionality to integrate -- figured I'd shoot this off and see if
you might be able to get something JPA wise in Cayenne by then.
