I had this on my blog, but maybe here someone listens, too.
Whats the idea ? its modular JPA. All my modularity is broken (now) when
it comes to my domain model. I would like to see an extensible
EntityManagerFactory (or at least its configuration) so that plugins can
contribute domain objects as needed. Are there any ideas about that ?
how do the Jazz people solve that ? (Dont know how the Jazz database is
integrated though).

Regards Thomas

I'm using EasyBeans OSGI and in July we had some discussions at the
newsgroup about this, so I created a JIRA there:
http://jira.easybeans.org/browse/EZB-294

the goal is to let EasyBeans create an EntityManagerFactory and publish
it as an OSGi service, so that multiple EjbJar bundles can use it.

but I think it'll take some time until they have integrated this

....of course it would be great to get a solution. I felt the same as you
after trying and integrating EasyBeans and then to see that OSGI
modularity isn't realized for JPA - but on the other side from my
experiences EasyBeans is the most flexible OSGI EJB3 - JPA solution.

next weeks I'll publish a sample Equinox-Riena-EasyBeans server - just
working on this...
