Hi :-) I am not sure, but I think in other Servlets(which are not your
loginServlet),
you can use:
...
HttpSession session = request.getSession(false);
if (session == null) {
response.sendRedirect(response.encodeUrl("/servlet/loginServlet"));
return;
}
Object obj = session.getValue("login");
if (obj == null) {
response.sendRedirect(response.encodeUrl("/servlet/loginServlet"));
return;
}
// other checking, for example, check if obj is a instance of the class
// with which you made your *value* in your loginServlet.
...
