Hi Florian,
It is possible to have multiple entity managers registering with the
same transaction, but you would want to make sure that there is no
entity overlap across them or you may be at risk for data
inconsistency.
In theory it should be possible to have persistence units with
different persistence providers (Gemini JPA and Aries JPA). I have
not tried it, but I don't expect there to be any problems.

PS Please use the forum rather than this list for Gemini questions.
That way people can post their own experiences in response to the
question, and there is a more searchable record for others to see
the questions/answers in the future.

Hi,
i now, that jpa entities from a persistent
bundle must not become used
in a entity manager from a different bundle.
So i try to figure out a
way to persist entities from
different persistent bundles in the
same transaction. Even if they are using different entity manager.
Eg:
txn.begin
modul1.persist(someBean)
module2.persist(someBean)
txn.rollback // will rollback
modul1 and module2
1) Would
OSGi JTA specification handle that
stuff properly?
2)
Can i use gemini JPA and apache aries JTA together?
Thanks a lot for
your answers.
