Hi sunita
Try this out
At starting of ur jsp page include a file say checksession.jps which will look somewhat like this
CHECKSESSION.jsp
<%@ page language="java" import="java.sql.*"%>
<%
if(session.getAttribute("SomeAttribute")== null)
{
give ur message and redirect
to some page say login page
ex:- out.println("<script>parent.location.href='Login.jsp'</script>");

}
%>
and on logout write this code

<%

session.invalidate();
out.println("<script>parent.location.href='Login.jsp'</script>");
%>

Hope this solves ur problem
cheers

I know this thread is very old...
But for the archives:

I wrote it like that:

<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>
<% 
session.invalidate();
response.sendRedirect(request.getContextPath() + "/index.jsp");
%>

Even in 2003, the use of scriptlets in JSP pages was discredited. Doing so in 2009 is just .

And, please read this.

Hey Friend use this code in jsp page

<%
if(request.getParameter("logout")!= null)
{
session.removeAttribute("uid");
session.invalidate();
response.sendRedirect("index.html");

}
%>

Again, as already pointed out. Java scriptlets should no longer be used in JSP pages.
