logout problem..
2 Answer(s)      4 years and 6 months ago
Posted in : JSP-Servlet


hi...
first of all thanks for ur help.Actually i m developing a web application whole of the functionality is completed but their is some problem with the the logout,i m not able to logout when that application runs . i m using eclipse with my sql as a back end.basically but i have done in the code i have used session object in project's servlet and jsp for trsferring info between various servlet & jsp.and made a logout servlet.which is called through a hyperlink which is displayed over every jsp page or u can say view(M.V.C),when a user login's and after doing some work he click logout he is reffered to logout servlet.And what i have done on that logout servlet i have invalidate that session by calling "session.invalidate();"
and
"session=null;"
but it don't invalidates , if some one click's on back button on browser he will enter in the application.and hence all the security collapes.
hope u have got what i want to explain.
once again once a person has logout he should not be able to enter in the application by just clicking on the back button.

Hi Friend,

Try the following code:

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> &nbsp;&nbsp;<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>

Hope that it will be helpful for you.
Thanks
