从servlet调用jsp页面而不使用会话变量

Question

Im trying to achive the requirement as below using netbeans, tomcat and servlet.

I'm submitting the form to the servlet "Servlet1" with userid. and in Servlet1, I am creating the statusmessage based on userid I got from form and that needs to be displayed on "welcome.Jsp" page.

my servlet code :

protected void doPost(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        String nextPage = "";
        response.setContentType("text/html");
        PrintWriter out = response.getWriter();
        String statusMessage = "";
        String emailId = request.getParameter("EmailId");

        try {

           int i = 1;
            if (i != -1) {
                if (i >= 1) {
                    statusMessage = "User Authentication Success";


                } else {
                    statusMessage = "User Authentication failed";
                }
            } else {
                statusMessage = "ooooppppsssss";
            }

        } catch (Exception se) {
            out.println(se);
        }
        // out.print(statusMessage);
    RequestDispatcher rd = request.getRequestDispatcher("welcome.jsp");
    rd.forward(request, response);
}

Problem is : Im not redirected to the page where I want to display the message and instead url end up in the same page and not redirected. I know we can setit in session and can be access from enter code here "welcome.jsp" by response.sendredirect but Is there any way i can achive without using the session?

Answer 1

You can set it as request attribute as

request.setAttribute("idName",userid);

and access it in JSP using JSTL as ${idName}

What is the error you are getting??
