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

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

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