[jboss-user] [EJB/JBoss] - DB Atomic commit operations

Hi I have a scenario in which I need to treat DB commit of 2 rows as one atomic operation. How do I achieve this using CMT? Any tips would be useful. Basically I have something like this. public class TestMDBean implements MessageListener { @PersistenceContext private EntityManagerFactory emf; @UserTransaction utx; private UserTransaction utx; private void updateLog() { //populate a pojo entity here in a collection. The collection has 2 objects corresponding to the two rows in the table. Roll back if a single commit fails. } I am not sure what kind of transaction strategy I need to use here. Let me know Cheers K View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4005434#...
