Here I am sending a String object from a servlet to JSP. I am getting NullPointerException when I run this servlet in tomcat server. I try to get String object using request.getAttribute("message"); in JSP but I am getting null value. How to solve this problem. The following is the servlet code.

import javax.servlet.*;

import javax.servlet.http.*;

import java.io.*;


public class JSPTest extends HttpServlet

{



public void doGet(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException

{

String message = "This is a test";

req.setAttribute("message", message);

PrintWriter out = res.getWriter();

res.setContentType("text/html");

out.println(" Hi ");

RequestDispatcher rd = getServletContext().getRequestDispatcher("http://localhost:8080/test/SerJsp.jsp");


rd.forward(req,res);


}

}
