Hi,
I'm trying to test my EJB-application with a couple of threads (~ 20) and getting a message from JBoss-Server:
Could not enlist XAResource!
javax.transaction.RollbackException:Already marked for rollback.
....
It's look like a problem of "race-condition", when different processes try to get the same data from DB.
Any suggestion, how to solve this problem?

Tanx in advance!
