Hi Andrey,
Write a separate LoginServlet wich puts within HttpSession some value
that marks the user has already logged in :
String currentUserId = // LoginServlet's job to find it..
mySession.putValue("LoggedUserId", currentUserId);
In all other servlets, you need to check only if
mysession.getValue("LoggedUserId"); returns a non null value.
If this call is null just call
response.sendRedirect("/servlets/LoginServlet") or what ever your
login servlet is named.
Another approach is to use http-server based authentication on all
requests beginning with "/servlet/" prefix. Then no user will get
access to any of your servlets before is authenticated.
