Java Programming

I am implementing a scenerio where I need to reset login status in the database to false when a user closes browser without logout. I am at fix, how do I do that ????? With the java script solution, its a browser dependent and may not work with all the browser. With java sessionListener, the sessionDestroyed() method is never called when browser is closed.

Plz. help... how can I capture the browser closing event. My application is running on Websphere and integrated with active directory for authentication and authorization.

Thanks in advance......
