Answer / Mahendra Prasad
Re-entrancy refers to a method being called recursively from within itself. In Java EE, Session Beans can be designed to be re-entrant as they support container managed transactions. However, Entity Beans cannot be explicitly specified as re-entrant. By default, Container Managed Persistence (CMP) Entity Beans are not re-entrant due to potential issues with concurrent access. But, Bean Managed Persistence (BMP) Entity Beans can be made re-entrant by using proper locking mechanisms.
