[confluence]

Page Created : OPENEJB : Transaction Annotations Transaction Annotations has been created by David Blevins (Sep 11, 2007). Content: The javax.ejb.TransactionAttribute annotation (@TransactionAttribute) can be applied to a bean class or it's methods. Usage of the @TransactionAttribute requires you to specify on of six different transaction attribute types defined via the javax.ejb.TransactionAttributeType enum. TransactionAttributeType.MANDATORY TransactionAttributeType.REQUIRED TransactionAttributeType.REQUIRES_NEW TransactionAttributeType.SUPPORTS TransactionAttributeType.NOT_SUPPORTED TransactionAttributeType.NEVER Attribute Types summary To ensure your method is invoked in a transaction, one of tree attributes can be used; REQUIRED, REQUIRES_NEW, MANDATORY. There's a much easier way to visualize the transaction attributes. Failing: NEVER, MANDATORY result in exceptions being thrown to the caller Correcting: NOT_SUPPORTED, REQUIRED result in the container correcting the transaction state   Failing Correcting MANDATORY REQUIRED REQUIRES_NEW SUPPORTS NOT_SUPPORTED NEVER
