Jeff Yu commented on ODE-704:
-----------------------------
I did some experiments based on Ode 1.3.3 last week.
Below is the couple steps that we need to do.
1. Refactor the dao-jpa module, pull out two JPA's API into the dao-jpa-ojpa
module, and then introduce a Factory class to produce the corresponding DAO
class for OpenJPA and Hibernate, added another dao-jpa-hibernate module for the
Hibernate's specific classes.
2. Need to update the buildr/hibernate.rb class to generate database script by
using hibernate built-in tool (known as hbm2ddl).
3. Need to separate the bpel-store module into two different modules. Currently
this module has four DAO classes, and they put both the JPA and Hibernate impl
into same jar with different package name. One issue is that in its produced
jar, it will include the *.hbm.xml file, these files will get loaded in our
JBoss by default, which means if we configure the jpa to use Hibernate, the
entity will get loaded twice.
4. Update the bpel-store's JPA classes. (By adding @Id annotation for Entity,
the OpenJPA will add it by default, Hibernate asks it to be declared
explicitly.)
5. Run more tests for verifying.
the code can be found at the jpa branch, it is at:
http://anonsvn.jboss.org/repos/riftsaw/branches/ODE/ODE-1.x-jpa/
will need to create some sub-tasks for those steps. and then provide patch as
each sub-task.
> clean up the JPA module, supports botht openJPA and Hibernate
