Subject: [Springframework-developer] OJB support

Hi everybody,
=20
On the occasion of the recent TSS thread on OJB 1.0 final, I've decided =
to
give OJB PersistenceBroker integration a go. I've already committed the
initial bunch a couple of hours ago, providing =
PersistenceBrokerTemplate,
PersistenceBrokerTransactionManager, etc.
=20
This initial stuff took just about 4 hours, including getting OJB to =
work
with a simple example! I was pleasantly surprised by how easy OJB is to =
set
up. I'm not fond really fond of its static initializer model, but it =
does
work and is simple enough to get going.

I'm currently working on support for exposing the JDBC Connection in
PersistenceBrokerTransactionManager and other refinements. I plan to add =
a
Petclinic data access version for OJB this weekend: As far as I can =
judge at
this point of time, this should be simple enough to do.
=20
One of the distinct characteristics of OJB's PersistenceBroker is that =
it
offers all of OJB's mapping and querying capabilities, but does not =
attempt
to provide object-level transactions, i.e. does not do automatic change
detection but rather rely on explicit store calls. For Petclinic-style =
web
apps, this is more than enough.
=20
The stuff in CVS does work already, so whoever's interested, feel free =
to
have a look at it :-)
