Subject: Re: manipulating the http requests.....

how do we call a method of a servlet using RequestDispatcher. With request dispatcher we can call a second servlet from one servlet, but if i want to call a foo() method inside the second servlet, how do i call it (even after using RequestDispatcher)... thats my question

Why won't a RequestDispatcher work?
