What happens when
1. "A" Bean calls "B" Bean and in a transaction context
2. B's business methos has @TransactionAttribute(REQUIRED)
3. B marks setRollbackOnly
Does container first rollback B's transaction before returning and then A rollsback it's transaction or does container rollsback A both A's changes and B's changes as well while trying to commit or rollback in A bean. I looked in EJB specs but found it confusing.
