)
<form method=get action=reqDispServlet> Name<input type="text" name="Name"/> Age<input type="text" name="Age"/> Button<input type="submit" name="Submit"/> </form> </body> </html>
Heres the Request Dispatcher
Servlet
:
package rrsPackage; import java.io.IOException; import java.io.PrintWriter; import javax.servlet.RequestDispatcher; import javax.servlet.ServletException; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; public class reqDispServlet extends HttpServlet { private static final long serialVersionUID = 1L; protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { PrintWriter pw=response.getWriter(); String s1=request.getParameter("Name"); String s2=request.getParameter("Age"); int num1=Integer.parseInt(s1); int num2=Integer.parseInt(s2); int ss=num1+num2; String sum=String.valueOf(ss); request.setAttribute("nn", sum); RequestDispatcher dispatch=request.getRequestDispatcher("page4"); dispatch.forward(request,response); pw.println("sd"); } }
Heres the page4.jsp: (not much jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> <title>Insert title here</title> </head> <body> <p>Confirmed !!
