Hello, thank you very much. You have turned me on right way. I have succesfully run the distributed transaction in two message driven beans. I had to make some changes to com.arjuna.ats.arjuna.coordinator.TwoPhaseCoordinar I don't know if it is bug or not. I hope somebody will tell me on the JBoss Transaction forum.
