Hi,
I am working with an old database without transaction, So I add
@TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
to my sessionbean. but i get this exception
EntityManager must be access within a transaction
when I persist an object.
If i comment the
@TransactionAttribute, the persist works, But i got a
javax.transaction.RollbackException
after invoke the EJB method.
what should i do to avoid these problems?
thanks in advance
liu
