Hi :-) I don't know how to do it with three html files mentioned in your email,
but from a book(ISBN:0-471-33229-1), I find a way to do it by
Servlet+HttpSession:
0 we need two/three Servlet class: LoginServlet, worker2Servlet, worker3Servlet
1 * in doGet/doPost/service of LoginServlet:
...
HttpSession session = request.getSession(true);
... //make a obj, obj is a instance of the class you want to put in
session.putValue("SessionName", obj);
response.sendRedirect(response.encodeUrl("/servlet/worker2(3)Servlet"));
...
* in doGet/doPost/service of worker2(3)Servlet
...
HttpSession session = request.getSession(false);
if (session == null) {
response.sendRedirect(response.encodeUrl("/servlet/LoginServlet"));
return;
}
Object obj = session.getValue("SessionName");
if (obj == null) {
response.sendRedirect(response.encodeUrl("/servlet/LoginServlet"));
return;
}
// other checking, for example, check if obj is a instance of the class
// you want to put in
...
Have a nice Saturday! :-)
