JSP/Servlet session Invalidate.
Hello Everyone,
I am not able to invalidate my session. Kindly help me out.
I am using:
Product Version: NetBeans IDE 6.0.1 (Build 200801291616).
Java: 1.5.0_15; Java HotSpot(TM) Client VM 1.5.0_15-b04.
Server: Apache Tomcat 6.0.14.
The following is my code:
Index.jsp
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!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=UTF-8">
<title>JSP Page</title>
</head>
<body>
<form action="setses" method="POST">
<input type="text" name="un" value="" />
<br>
<input type="password" name="ps" value="" />
<br>
<input type="submit" value="LOGIN" />
</form>
</body>
</html>

Setses.java (Servlet)
package ses;
import java.io.*;
import java.net.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class setses extends HttpServlet {
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
String un = request.getParameter("un");
String ps = request.getParameter("ps");
HttpSession myses = request.getSession(true);
try {
myses.setAttribute("un",un);
myses.setAttribute("ps", ps);
out.println("<html>");
out.println("<head>");
out.println("<title>Servlet setses</title>");
out.println("</head>");
out.println("<body>");
out.println("<a href='view.jsp'> view </a>");
out.println("</body>");
out.println("</html>");
} finally {
out.close();
}
}

View.jsp
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!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=UTF-8">
<title>JSP Page</title>
</head>
<body>
<% HttpSession myses = request.getSession();
if(myses.getAttribute("un").equals("")||myses.getAttribute("ps").equals(""))
{
out.print("Invalid ses");
}
else
{
out.print(myses.getAttribute("un"));
out.print(myses.getAttribute("ps")); %>
logout
<%}%>
</body>
</html>

logout.jsp
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<body>
<h2>Hello World!</h2>
<%
HttpSession myses = request.getSession();
myses.invalidate();
%>

Web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

Now the issue is even after logout.jsp if I visit the view.jsp as http://localhost:8080/ses/view.jsp - the session is not invalidated... Kindly tell me where I am making mistake.
