>From your source code, I guess you used bitronix.
You have to make bitronix initialize it, and by this, bind java:comp/UserTransaction to the transaction manager,
So, to do this:
You should try:
bitronix.tm.TransactionManagerServices.getTransactionManager().begin(); (actually, bitronix.tm.TransactionManagerServices.getTransactionManager() should do it)

I did, but I get the same Exception as before, but on this new line
UserTransaction ut = (UserTransaction) new InitialContext().lookup("java:comp/UserTransaction" );

I still don't understand where the "java:comp/UserTransaction" will be accessible/come-from/being-created ... ?
