RE: Session Expirey hooks

Yes you are probably correct, cut & paste error.... oops

It would probably be very useful to be able to switch on any or all of those
listeners as a general purpose feature...for clean up, logging, testing,
debugging etc

Subject: RE: [Barracuda] Session Expirey hooks

Hi Andrew,

Thanks for your suggestion, but isn't it true that using this method, I
will only be notified when a session is passivated or activated, not
expired?

Ideally, I would be notified just before the session is expired, so that
I can fire a Barracuda Control event to do the cleaning up.

Whilst looking at the Servlet 2.3 API, I also found:
javax.servlet.http.HttpSessionListener. It looked like it may do the
job, but the docs say that my implementation will only be notified
_after_ the session has been expired, and that "To receive notification
events, the implementation class must be configured in the deployment
descriptor for the web application." I am not sure how that fits in with
Enhydra applications, but I know that we would rather register the
listeners on the fly from Barracuda Event handlers than at Enhydra
startup.

I will look further into this, but any additional ideas at this stage
would be much appreciated.

James.
