double login block

hi all,

Here is my problem:
I cant allow a user to login into the system twice from different machines.
I'm thinking in use a singleton that handles a HashMap with all user's login, so if the same user try to access from other machine the system will block him.
I wanna know how is the best way to put the user's login out from the HashMap, once the user will never click on "logout" button to exit. Is there a eventlistener to inform the singleton that the user's session has expired?

or, if anyone have a better way to do that, please tell me!


* Sorry about my poor english!

Romero, please do not cross-post the same question in multiple forums. It wastes people's time when multiple redundant conversations take place. Please continue any discussion of this topic here.
