how
one can integrate Hibernate (or JPA Hibernate aspect) with CMP on
OpenEJB.
Where is Hibernate being used? Is it part of MDB or SLSB? Is BMP with
Hibernate not an option as far as ejb2.1's concerned? Where would
hibernate help openejb3 to mimic the target websphere 6.1 server?

Thanks for your concern! ;) Our legacy application is using
Hibernate as
the persistence provider - JEE Entity Beans are not used at all. So we
had to embed Hibernate into our EAR and deploy it on target AS. BMP
is a
valid option but we wanted CMP (descriptive transactions). So, if you
are building normal JEE application with entity beans or JPA you'll
probably never need to embed Hibernate.
JPA has a design very similar to Hibernate, and you can bundle a JPA
implementation, such as OpenJPA, with your application. As long as
you are on Java5+ in WepSphere, OpenJPA should run fine. Of course,
your application is already written so, I doubt you'll want to switch
to JPA right now.
