Hi!!!!!
instead of storing bean as a session object store a variable in the session
to null or anyother value if th user is logged in. Instead of having the
scope of the bean as page change the scope to session. This will solve ur
problem.
And whenever u want to check check for the exsistece of this variable in
the sesson.

Subject: problems using session
Jsp Gurus,
I trying to do user authentication by using a java class called
Administrator in my jsp. I need to attach this object to the session so i
can check on each page if this is not null and so the page can be viewed
else send them to the login page.
The code is
<%@ page language="java" import="myBeans.*" %>
<jsp:useBean id="auth" scope="page" class="myBeans.ValidateAdmin" />
<jsp:setProperty name="auth" property="*"/>
<%! String display;
%>
<%
display = "launch.jsp";
try
{
Administrator admin = auth.authenticate();
// check if the user is allowed to view the next page
if (admin != null)
{
out.println("The admin is not null");
session.setAttribute ("administrator",admin);
}
%>
<jsp:include page="nextpage.jsp" />
<%
}
catch (Exception e){}
%>
It works fine till i add the line
session.setAttribute() to add the object in the session. When i do that i
get the following error
Fri Jul 14 13:50:45 EDT 2000:<E> <ServletContext-General> Compilation of
