Hi Craig,

> How goes it, nice to hear from you again!

its going ok.  <shamless-plug>I'm actually working with a friend of mine atm
trying to get a small company (partnership at this stage) off the ground -
set our own rules, see things done properly etc.  So if anyone has any
projects they'd like to see a very high quality proposal for then let me
know!</shameless-plug>.

I first looked at it a last year, but didn't really have a chance to work
with it properly.  For the past few months I've been using it with Tomcat as
a lighter alternative to running EJBs... when developing for small
businesses, being able to run on tomcat instead of requiring an EJB server
saves them a few $$$.

Hibernate's transactional model is very pluggable.  As I understand it,
Hibernate supports JTA and is well supported inside JBoss (I've cc'd this to
the hibernate list where you might be able to get more info).  A also
believe that it supports plugging in of alternative transactional models
through its own API, although I'm not sure of the status of this - its
something I read on the mailing list.  Re locking, it supports optimistic
locking - check the docs (http://hibernate.sf.net).  Version 2 betas are
very stable from my experience, and I believe the only reason that version 2
hasn't been made final is for one or two pieces of functionality.

Certainly worth a look.  It also has good XDoclet support in XDoclet CVS.

cheers
