[jboss-user] [JBoss Seam] - Re: Exception:Transaction is not active

Thank you very much indeed

just two questions. 
if we mark the class with @Transactional, will it manage all transaction? 

second, is this right?


  | 	public int save(StoredQuery query) {
  | 		try {
  | 			em.getTransaction().begin();
  | 			em.persist(query);
  | 			em.getTransaction().commit();
  | 			return 0;
  | 		} catch (Exception e) {
  | 			em.getTransaction().rollback();
  | 			e.printStackTrace();
  | 			return -1;
  | 		}
  | 	}
  | 
  | 

I change that save() method to rollback transaction to prevent above problem, but it throws this exception:

java.lang.IllegalStateException: Illegal to call this method from injected, managed EntityManager

what is wrong with this?
