mapping.What is those difference in work effect?

Answer Posted / ramanjaneyulu

whatever Tirupathi Rao told it is correct. I am adding few
more words to this question.We need to follow either
extension matching or directory match to achieve "Front
controller" design pattern. By using this design pattern
only we can able to trap all the requests to Action classes
and forwarding control to ActionServlet class.
