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
