[Wicket-user] session management

[Manuel Corrales]

Hi, i've asked this question once but dont get a solution. So here i go again:

I have some clues about stateful beans and stateless beans but not too much. What i need is that when a user logins, create an object and that that object exists during the user session (to logout). Now i think this is easy to do with a app server, but all i have is tomcat and wicket. Is there a way of achieve this?

Another related question is: How can i forbid access to a non loged user?

Thanks very much.
