The answer to the first question is TX_REQUIRES_NEW. TX_REQUIRED just marks the ejb or method as being required to run in the context of a transaction. The transaction that it runs within may or may not have been created by the container. TX_REQUIRES_NEW says that the ejb or method must run in a new transaction that is demarcated by the container. Your answer for number two is correct.
