TransactionManager and BMT

[rpdmiranda]

Hi,

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).

Thanks,
Robson

Using JtaTransactionManager is perfectly legal in a BMT bean. It does not violate anything in the J2EE specs: it simply uses the UserTransaction interface that is available to bean developers according to the J2EE specs.

The use of UserTransaction via JNDI lookup isn't forbbiden by the spec?
Also, I'm interested in the advanced features, such as transaction suspend/resume (which are provided by TransactionManager).

Thanks
