Thanks a lot for your answers, guys. I will try the 2 approches. Cheers.

Re: How to get a list of the connected users ?
Maybe you can write a session listener to intercept session destruction (give a look at servlet api, in particular HttpSessionListener). For sessions that do have an associated (logged in) user you can set the isConnected flag to false then. I wouldn't recommend keeping these flags in a persistent store anyway. A session manager that keeps an in-memory transient set of logged in users feels better to me. The users themselves need not to be kept all the time in memory, of course, that would swallow up resources. This way, if your application hangs up your currently logged in users state will disappear together with your sessions.

Implement an HttpSessionListener that clears the flag when the session is destroyed, and register it in your web.xml. This will handle both the case when they press the Logout button and when the session expires due to inactivity. http://java.sun.com/j2ee/sdk_1.3/techdocs/api/javax/servlet/http/HttpSessionListener.html jk - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
