Thanks to all who replied to this query.
Simon, I didn't want to use an 'InstancePool' because the initialisers for
each instance are unique for each session's use of the library. That would
be my preferred solution if this weren't so.
Sam, did you mean HttpSessionBindingListener instead of HttpSessionListener
(as Chris suggested)? HttpSessionBindingListener looks like the way to go.
Thanks again,
Mark
