I'm developing some MDBs with bean managed transaction. I would like to use a more fine grained transaction control for the beans used in this MDB.
Is it possible to use JtaTransactionManager within an BMT bean? I tested in JBoss using UserTransaction and TransactionManager, and it only worked if I specify only the transaction manager, setting usertransaction to null in the JtaTransactionManager definition.
I would like to know if this setup is accepted by the EJB standard (use TransactionManager inside BMT bean).
