can any one suggest me how to handle the userdefined exception ,if it is possible to throw from entity bean

I don't think that you can catch user-defined exceptions in EntityBean
better to throw a new EJBException() and catch that exception on the client side i.e Session Bean from where you are calling the buisness methods.Here you show a user defined exception.
