hi prateek,
u need not make any changes in deployment descriptor. That means
transaction is done explicitly but not implicitly by the container.
Try using following code in ur session bean, it will surely work.
U need to import following packages
import
javax.transaction.UserTransaction;
import javax.transaction.SystemException;
import javax.transaction.HeuristicMixedException;
import javax.transaction.HeuristicRollbackException;
import javax.transaction.NotSupportedException;
import javax.transaction.RollbackException;
Context ctx = getInitialContext();
tx =
(UserTransaction)ctx.lookup("java:comp/UserTransaction");
tx.begin();
if(!gotException)
{
try
{
tx.rollback();
//System.out.println("%%%%%%%rolled backwwwwwwwwwwwwwwwwwwwwwww");
}
catch(Exception e)
{
}
}
else
{
tx.commit();
//System.out.println("%%%%%%%committed");
//return true;
}
//throw new Exception();
With regards
