Also, if I inject a Hibernate Session, and a HttpServletRequest, how
does threading work with that?
I mean, one thread could be running through the singleton, processing
one request against the session, right as another one enters. How do
you inject 2 per-thread managed hibernate sessions into a singleton?
I guess I can't wrap my head around injecting services into singleton
services, and yet having that singleton remain safe, especially when
the injected services are potentially per-thread.
Also, when working with a page using hibernate and injecting a
session. Say I have a event handler that deletes a subobject (
onActionFromDelete ), and of course I annotate it with commitAfter
because I want that change saved. So when is a new session created and
injected? When OnActivate is called again to re-render the page?
I guess I don't understand the threading and magic in services ( so I
know how to write my service ).
