17.6.2.2 Required The Container must invoke an enterprise Bean method whose transaction attribute is set to Required with a valid transaction context. If a client invokes the enterprise Bean's method while the client is associated with a transaction context, the container invokes the enterprise Bean's method in the client's transaction context. If the client invokes the enterprise Bean's method while the client is not associated with a transaction context, the container automatically starts a new transaction before delegating a method call to the enterprise Bean business method. The Container automatically enlists all the resource managers accessed by the business method with the transaction. If the business method invokes other enterprise beans, the Container passes the transaction context with the invocation. The Container attempts to commit the transaction when the business method has completed. The container performs the commit protocol before the method result is sent to the client.
