With CMP, you must only implement 3 and 4, but you can also implement ejbSelect -methods. However, the name of ejbSelect -method can never be just "ejbSelect". With BMP, you must implement 3 and 4 (as with CMP), but you could also implement finder methods (if you have specified finders other than findByPrimaryKey in your home interface). Again, the name of the finder cannot be "ejbFind". So the answer is clearly "3 and 4".
