Re: Way to cleanup *before* session terminates ?

[Charlie Toohey <ct...@pacbell.net>]

Just tried implementing HttpSessionActivationListener, and the 
sessionWillPassivate method does not get called when the session is 
invalidated. I'm using Tomcat 4.1.24.  Maybe its not suppposed to ? Per the 
docs, this is called when the session is migrating between VMs and when 
persisting sessions, but all I've got going is a session in a single VM being 
created and being invalidated.
