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