Why not? Where can I find a PetStore application in Cocoon to start with? If the results will be interesting we can post them to TheServerSide.com.
You can find a "petstore" block in Cocoon, but AFAIK it uses straight JDBC. You might be more productive, maybe, by adapting my CHS <http://new.cocoondev.org/main/g1/43> sample to use JDO as an alternative to Hibernate. Given its stricter separation of persistence from business logic and presentation, it will probably be easy to provide JDO-specific implementations of DAO interfaces.
I've repeatedly tried to push the OJB supporters here to do the same for OJB, but they seem to be quite busy doing for-pay work at the moment ;-).
