<DL>
<DD>Obtain the transaction demarcation interface.

 Only enterprise beans with bean-managed transactions are allowed to
 to use the UserTransaction interface. As entity beans must always use
 container-managed transactions, only session beans with bean-managed
 transactions are allowed to invoke this method.<DD><DL>

    instance can use for transaction demarcation.<DT><B>Throws:</B><DD><CODE>java.lang.IllegalStateException</CODE> - The Container throws the exception

<DD>Mark the current transaction for rollback. The transaction will become
 permanently marked for rollback. A transaction marked for rollback
 can never commit.

<DL>
<DD>Test if the transaction has been marked for rollback only. An enterprise
 bean instance can use this operation, for example, to test after an
 exception has been caught, whether it is fruitless to continue
 computation on behalf of the current transaction.

 Only enterprise beans with container-managed transactions are allowed
 to use this method.<DD><DL>
<DT><B>Returns:</B><DD>True if the current transaction is marked for rollback, false
   otherwise.<DT><B>Throws:</B><DD><CODE>java.lang.IllegalStateException</CODE> - The Container throws the exception
