I wonder, what is the correct way of exception handling in the MVC design? For example, in the project I have a method name myFunc() in DAO interface and implemantation, and in service interface and implementation I hava this method. And from a jsp as I call an action method, in action class I call the method,moreover. So I have 3 places to catch the exception, MyClassDaoImp.java MyClassServiceImp.java MyClassAction.java I think that, it is better programming style to catch the errors at same place. I mean I caught IO exception at service class and I caught database exception at dao class seem as if a wrong programming style. Shortly, how should I hande exception    More>>
