Required will use an existing transaction if present or begin and commit/rollback a new one if not. Mandatory requires an existing transaction and will not begin its own. RequiresNew will always begin a new transaction. Note that the container will suspend the current transaction, if there is one, until this method completes. Supports will use an existing transaction if present but does not require one. NotSupported will suspend an existing transaction while the method executes. Never will fail if called within the context of an existing transaction. To clarify, the difference between Mandatory and Required is what happens when the method is called outside the scope of an existing transaction. Required will begin a transaction and Mandatory will throw an exception. -- David Harkness Sony Pictures Digital Senior Software Engineer 310.482.4756 [EMAIL PROTECTED] ------------------------------------------------------- This SF.Net email is sponsored by OSTG.
