When you want send your request to another servlet/jsp from
your servlet, we can use RequestDispatcher.

There are two ways to get reference of RequestDispatcher.

1)If you get requestdispatcher reference from
ServletContext, you have to specify the absolute url as
argument in getRequestDispatcher method like below.

RequestDispatcher dispatcher =

getServletContext().getRequestDispatcher("/my_other_app/servlet/SomeServlet");
dispatcher.forward(request, response);

2)If you get requestdispatcher reference from
ServletRequeset, you have to specify the relative url as
argument in getRequestDispatcher method like below.

RequestDispatcher dispatcher =
request.getRequestDispatcher("SomeServlet");
dispatcher.forward(request, response);
