Re: Ozone & EJBs

I've been developing EJB's using J2EE for a couple of years, mainly
SilverStream and, recently, JBoss. It is possible to use Ozone for
SessionBeans today but I have been thinking about trying to do something to
make it possible to use Ozone for Entity beans as well -maybe creating an
EntityPersistanceManager to handle the job?
Then on the other hand the connector architecture in the next version of
J2EE (2.0) might provide another way to use Ozone together with a J2EE
application server. I think convenience and features are more important than
performance when considering this. It would be great if JBoss and Ozone
could work together easily so that one could easily create an OO view of
relational data with J2EE for the legacy systems and then use Ozone for new
applications and as a front end developer you would have one way of
accessing objects and calling business methods that would combine the power
of EJB's with Ozone.

Do you or did Mark have any ideas on possible ways of integrating the two?
