Hi All, I know that JSPs cannot implement an interface, cause in general it does not make sense, cause no body is going to call the implemented method.
It can extend a class. The reason could be to use the methods of the extended class. But since the 'customised hierarchy' of a jsp does not matter much to a servlet container, why it provides an option to extend. The usage of calling implemented methods can be fulfilled by making the instance of the class, rite?
