Try

  |    UserTransaction ut = ..
  |    ut.setTransactionTimeout(5); // 5 second timeout
  |    ut.begin();

  |         {
  |         }
  | 
  |         // Transaction has timed out here
  | 
  |         DataSource ds = ...;
  |         ds.getConnection().close(); // Oops can't enlist in dead transaction
  |    }
  |    finally
  |    {
  |        ut.rollback();
  |    }

If you need to do out-of-bound communication (i.e. read the database
even if the transaction has failed) then you need to use a different transaction,
either RequiresNew or no-tx-connection-manager.

There's nothing you can do in the dead transaction.
