In the servlet 2.3 API (implemented by Tomcat 4.0), there is a new application event listener interface (HttpSessionActivationListener) that is used to declare application classes that want to be notified when a session is about to be passivated (i.e. serialized out), or when it has been reloaded -- possibly in a different JVM.  If/when Tomcat 4.0 supports session serialization at other times, it will fire these events so that your application will know about them.
