RE: How do I determine sessions within Tomcat?
Mark, Another option is to write a callback class that is registered with each session using the HttpSessionBindingListener interface. Each time a session is destroyed, either explicitly by the user or implicitly by Tomcat (user just closed browser) then your widget should have its valueUnbound method called and you could update your DB. I haven't worked with the SessionListener before but that sounds more tailor made for the purpose you intend than my solution above. Jamey -Original Message- From: Mark W.

Re: How do I determine sessions within Tomcat?
you would probably want to write a SessionListener, and plug it into tomcat. Turansky, Mark wrote: I am required to track users and their sessions in my web application. Is there a way to access all the sessions currently held in server memory? My application is tracking users in a database table. Upon login, I log the session id along with a timestamp and other pertinent information. If the user specifically clicks the "log out" button, I can update my table with another timestamp, but I assume many will simply timeout.

I was hoping to make a simple maintenance thread in the background that would check existing sessions against my database table for this purpose.
