Forward parameters to jsp from servlet

Question

Is there a way to send parameters from servlet to jsp without redirecting the browser to that page?

RequestDispatcher disp = request.getRequestDispatcher("shoppingCart.jsp");
disp.forward(request, response);

Answer 1

There can be one way as below:

RequestDispatcher disp = request.getRequestDispatcher("shoppingCart.jsp"+"?myParam=myValue");
    disp.forward(request, response);    

If you are fine with "GET" method then you can solve this problem with appended parameters.

Answer 2

Well you can either set the attributes(used in case of internal communication with servlets or servlet to jsp or vice-versa) to the response object and forward the request you can achieve this as :

      request.setAttribute("someKey","someValue");

You can also use the session scope to share the attributes between servlet and jsp like this:

     Http session = request.getSession();
     session.setAttribute("someKey","someValue");
