将参数从servlet传递到jsp页面

Question

I have to pass parametrs From servlet to jsp .Iam using the following code.Is it possible to pass parameters through this way?

String val="Testvalue"
RequestDispatcher dispatcher = getServletContext().getRequestDispatcher("/index.jsp?valpass=val");
        dispatcher.forward(request, response); 

In jsp

String value=(String)request.getAttribute("valpass") ^

Answer 1

if you forward from servlet to jsp you should set as attribute do

request.setAttribute("key","value")

parameter is mainly used in communicating with client to server. and use attribute as internal message passing
