9 years ago

I have a web application where I am using session to remember the username throughout the session

HttpSession session =request.getSession();
session.setAttribute("LoginName",request.getParameter("username"));
request.setAttribute("uname",request.getParameter("username") );
but then when I am accessing the username in a jsp one jsp file is getting the data but another jsp file is not able to get data and also a servet file is not able to get the session value??

-------------------------------------------------------------------
addUser.jsp ///the file that dosn't recive the session value.

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@page import="java.sql.*,java.util.*,mypackage.*" %>
<%@ page isErrorPage="true" import="java.io.*" %>


<%out.print(session.getAttribute("LoginName")); %>
-------------------------------------------------------------------
addUserController.java // the servlet file that doesn't receive session

HttpSession session=request.getSession();
System.out.print(session.getAttribute("LoginName"));
//System.out.println("hello user adder");
String loginNam=(String)session.getAttribute("LoginName"); //Set the user id in session
System.out.println(loginNam);
whenever I thyed to access the session it always giving null.



what can be the reason???

Can you please tell me the full code for session.?

thanks in advance.
