Servlets is not OO? I think discussion of design patterns, refactoring
methodology, modeling, and OO principles is highly germane to any discussion
involving servlets. It's good to get back to the roots of things once in a
while; it keeps us on our technical intellectual toes.
What I'd like to see more discussion on is the place servlet 2.3 filters
have in MVC. Nic and I debated this a couple of months ago but no one
joined the conversation. Interestingly, at JavaOne this year, the
presenters at the seminar I attended on using filters pretty much coincided
with Nic's position.
I missed Jason, though...he was at a late-night session and I was at
Fisherman's Wharf. ;-)
Cheers!
