Urgent solution EJB3.0 with OpenJPA

[Rajesh Yarlagadda <ya...@hotmail.com>]

Hi ,

i am working on EJB3.0 with Toplink for container managed transactions on
Glassfish server.

i'm moving to WAS7 with Apache OpenJPA.

i have a problem in this scenario:

i have two entities TableA.java(TableA in database) and TableB.java(TableB
in database) with unidirectional one-to-many from TableA(one) to
TableB(many).

While persisting the TableA, toplink orm creates another JOIN table for
one-to-many mapping with name " TableA_TableB" table with TableA primary key
as foriegn and TableB primary key as foriegn and both act as composite
primary key mantains one-to-many mappings.

Is there any such kind on mechanism implemented by OpenJPA EJB3.0 container
managed one-to-many mappings to create or identify existed the JOIN Table?

Thanks,
Rajesh Yarlagadda

I think @JoinTable should help. Please check
http://openjpa.apache.org/builds/2.0.0/apache-openjpa-2.0.0/docs/manual/manual.html#jpa_overview_mapping_assoccoll
