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. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4213850#...
