Hi!
I have two UserTransaction - outer and inner. If I rollback outer, inner transaction rollbacks too by default. How I can to create new independent inner UserTransaction?

UserTransaction ut1 = new UserTransactionImp();
ut1.begin();
// some work 1

UserTransaction ut2 = new UserTransactionImp();
ut2.begin();
// some work 2  - I want to save this work!
ut2.commit();

ut1.rollback();

P.S.  My environment: Hibernate + Guice + Jetty.

Hi,

Try using the UserTransactionManagerImp instead, and call suspend() right before starting the second transaction, like this:

TransactionManager utm = new UserTransactionManagerImp();
utm.begin();
...

Transaction t1 = utm.suspend();
//start new tx - you can reuse the same utm instance or another
utm.begin();
...
utm.commit();

utm.resume ( t1 );
...
utm.rollback();

HTH

It works, thank you!
