Hi Nakata, I'm not sure what exactly you're trying to find out here? The HttpServletRequest interface has a getParameter method for grabbing parameters that have been set in the request object via a POST or GET.
The request object holds a lot of information pertaining to the request thread. You would pass that object any time the method you are calling will need access to any of that information.
