Hans-
We might not have Jonas' TransactionManager location configured in
the automatic TM lookup in OpenJPA. Can you try to manually specify
it with the following property:
openjpa.ManagedRuntime: jndi(TransactionManagerName=java:comp/
UserTransaction)
if that doesn't work, try:
openjpa.ManagedRuntime: jndi(TransactionManagerName=/
UserTransaction)
(apparently, Jonas' UserTransaction implementation is also their
TransactionManager implementation)
If that doesn't work, can you post the complete stack trace?
If it does work, please let us know so we can add it to the list of
auto-discovered transaction managers.

Hi there,
I'm trying to migrate our "old" J2EE1.4 / EJB2.1 applications
persistence to
openJPA. Currently I got stuck when
trying to configure OpenJPA persistence, when creating the
EntityManagerFactory and the EntityManager instance,
I get the following error:

Currently I'm running the application within the JOnAS 4.8.3 J2EE
Server.
How can I configure open JPA to
use the provided managed Transactions of JOnAS? (this works also with
Hibernate 2.x so I assume it should
somehow be possible with openJPA?)
any help appreciated!

HANS
