[jboss-user] [EJB 3.0] - Re: Can't get @TransactionTimeout to work

[mihai.ratiu]

My objective is to set a different timeout (greater than default of 5 mins) for a method that need to process a group of objects in a long transaction. So I tried to use the @TransactionTimeout annotation. Below is a simplified pseudocode with what I want to do. 


  | @PersistenceContext
  | EntityManager em;
  | 
  | @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
  | @TransactionTimeout(3600)
  | public Long doLongTransaction(List<BaseEntity> entities) 
  | {
  |       for(BaseEntity entity : entities)
  |       {
  |            if (condition) 
  |                 persistEntity(entity);
  |            else
  |                updateEntity(entity);
  |       }
  | }
  | @TransactionAttribute(TransactionAttributeType.REQUIRED)
  | public void persistEntity(BaseEntity entity)
  | {
  |     em.persist(entity);
  | }
  | @TransactionAttribute(TransactionAttributeType.REQUIRED)
  | public void updateEntity(BaseEntity entity)
  | {
  |     em.merge(entity);
  | }
  | 

If I try to set a minimum timeout to see if the transaction for this method will timeout let's say, after a minute it doesn't work, it will only timeout after the default 5 minutes value.
Am I missing something. Is there any other possibility to set a different transaction timeout for a method without affecting the global transaction default timeout?

Thanks, 
Mihai
