Number of users restriction

Hi all,

In a Web-J2EE application deployed on WebSphere, I'm looking for a way to restrict the number of users.

For exemple, if I allow 10 users, I want the 11th who tries to login to be rejected.
Is there any simple way to do that ?

You can set max in-memory session count property to 10 in web container using admin console. Also inside your entry servlet where you are obtaining session for a successfully authenticatde user, you need to put a check (import this package in your code
IBMSession sess = (IBMSession) request.getSession();
if(sess.isOverFlow()) throw new ServletException("Maximum number of sessions reached on the server");

Thanks Arvind .

But how can it work on a clustered environment ??
Can I define the max-session for a whole cluster ?
I agree. Here's the link:
