Java Servlets and HttpSessions

Question

Very basic question. I have a portal containing several servlets, one of which takes care of logging in (but only as an admin). How do I use HttpSessions between Servlets to know if the admin is signed in?

Thanks in advance!

Answer 1

Whenever your admin users signs in put something like session.setAttribute("admin","true");

check this as session.getAttribute("admin") to see if admin is logged in

Answer 2

set an attribute in session

session.setAttribute("isAdmin",true OR false);

At the login time decide the user type and set it.
