Interview Question: What is difference between EJB 1.1 and EJB 2.0?
By: AshQuestion:What is difference between EJB 1.1 and EJB 2.0?
Answer: The bulk of the changes in EJB 2.0 are found in the definition of a new CMP component model. Itâ€™s radically different from the old CMP model because it introduces an entirely new participant, the persistence manager, and a completely new way of defining container-managed fields, as well as relationships with other beans and dependent objects.
