Passing data from servlet to another servlet using RequestDispatcher

I am trying to pass data from one servlet to another using the RequestDispatcher. This is my code for the Dispatcher.

String address;

address = "/Java Resources/src/coreservlets/MapOut.java";

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

When I try to run it, it gives me an error saying the path is unavailable. Do I have to include something for the dispatcher to send to another servlet?
