getParameter() and other methods....

[venkatesh rajmendram]

Hi,
This is a basic question....which is pondering in my mind. We have interfaces HttpServletRequest and HttpServletResponse...
When a servlet lets says extends HttpServlet and implements method
doPost( HttpServletRequest req, HttpServletResponse res) {
String whatever = req.getParameter("MyParm");
}
Where is actually getParameter() method implemented ??? is it in the container ?? can we see at its implementation ? is it some network specific ?
Any information in this regard will be helpful...
Thanks
Venkatesh

as the name sugests, it is implemented in the HttpServletRequest .

Hi...
BTW the HttpServletRequest is an interface...There will not be implementation of getParameter() in interface....It should be implemented in some concrete or abstract class...
So still the question remains...

Yes, the actual implementation of HttpServletRequest is provided by the Container!

The container with wrap the client request into a nice object(not sure of what class ) that implements the HttpServletRequest interface which is provided to our servlet's http methods.
