[Springframework-developer] OJB support

[<jue...@we...>]

Hi everybody,

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.

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.

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.

The stuff in CVS does work already, so whoever's interested, feel free =
to have a look at it :-)
