Use session.invalidate() method to close the session.Here is an example.
1)login.jsp:
<html> <head> <title>User Login</title> </head> <br> <body Bgcolor ="#0099cc"><hr><hr> <form method="POST" action="action.jsp"> <p><b>UserName:</b> <input type="text" name="UserName" size="10"></p> <p><b>Password:</b> <input type="Password" name="Password" size="10"></p> <p><input type="submit" value="Submit" name="submit"><input type= "reset" value="Reset" name="reset"></p><hr><hr> </form> </body> </html>
2)action.jsp:
<%@page import="java.util.*" %>
<script>
function go() {
window.location.replace("logout.jsp",'window','toolbar=1,location=1,directories=1,status=1,menubar=1,scrollbars=1,resizable=1');
self.close()
}
</script>
<%String str = request.getParameter("UserName");
session.setAttribute("UserName", request.getParameter("UserName"));%>
Welcome to <%= session.getAttribute( "UserName" ) %>
<% if (session.getAttribute("UserName").equals("")){%>
<a href="login.jsp"><b>Login </b></a>
<%}
else{%>
<a href="javascript:go()"><b>Logout</b></a>
<%}
%>
3)logout.jsp:
<%session.invalidate();%> You have logged out. Please <a href="a.jsp"><b>Login</b></a>
