ODE PXE Dependency in Hibernate
I was looking at the ODE Roadmap (http://wiki.apache.org/ode/RoadMap) and
saw the following item :
There is a desire to remove the current PXE dependency on Hibernate, which
is licensed under the LGPL. The abstraction layer developed for BPE could be
useful for a common Ode implementation. The BPE implementation relies on
J2EE CMP for stateful persistence. Stateless usage scenarios do not require
persistence. EJB3 might be a suitable candidate for state persistence where
needed.
Could you guys let me know the status of it ? Does ODE still have the
Hibernate dependency ? If so, have you guys investigated any possible
candidates for replacing Hibernate ?

You will find the interfaces in the bpel-dao module. The Hibernate
implementation is then in dao-hibernate. The dao-hibernate-db-derby module
is just used to generate a derby database pre-loaded with the right schema.
You might want to have a look at this as well but should start with the two
other modules first.

Thanks for the answer Matthieu
I'd like to take a quick look at this... as I'm not so familiar with the
project, could you please give me some guidance on where to start looking
at this ? should I start at dao-hibernate and dao-hibernate-db-derby ?

Hi Luciano,
The issue is still pending yes. The possible replacement that have been
mentioned several times is OpenJPA. It's also an incubated project and has
been donated by BEA (it's mostly what used to be SolarMetric Kodo).
Would you be interested in helping out implementing this?
