Hi,
I'm developing an e-commerce application using two session EJBs which write on two DBMS (mySQL).

I need only to rollback the writing transaction on the two DBMS but I have some problems : using Bean Managed Transaction the rollback via UserTransaction object hasn't any effect.

I can only make rollback via java.sql ... but I would like to manage it via Bean.

I think mySQL can't manage transactions, even if I'm using InnoDB tables.

please a little help ! thanx
