Working version of Ode with openJPA

[Raja Balasubramanian/MAXIMUS <Ra...@maximus.com>]

Hello,

 

Is there any way to get a working version of Ode with openJPA as
persistence layer?

If not, when can I expect a version with openJPA?

Right now I'm using hibernate, and it's not working with Oracle.

If I can get an openJPA version, then I will redo the testing with Oracle?

 

Thank you

Raja

The NPE has been fixed by Mathieu a few hours ago (thanks !).
It was caused by the introduction of the versioning scheme which
did not work with jbi.

The JPA layer is completely broken at the moment. Mainly because
the main class is not managed by jpa anymore, so that the
jpa layer is completely unusable.

Raja,

The openJPA implementation was working with some known issues.

1) It was using iterators to find objects within the store. This works for a
small store however it would not work well with a large number of deployed
processes and instances. To that end I am currently working on replacing the
iterators with JPQL query statements ( Maciej started this work and posted a
patch ).
2) The management query API is not supported. Currently working on that as
well.

Recently Guillaume reported an NPE while using the openJPA implementation
and I'm not really sure where the problem is and haven't had time to dig
into it. My current understanding is that it could have something to do with
one of three things ...

A) Changes in the deployment store.
B) Refactoring in the DAO interfaces.
C) The openJPA implementation of BPELDAOConnectionImpl needs to be
refactored based on B.

I am currently working on 1 & 2 as I find time. I can't speak to (A,B,C ),
as I was hoping that in the process of testing 1 & 2 the answer to ( A,B,C )
would become evident.

If you need any of this with more certainty I would be happy to chat about
any ideas you have ( or anybody else ) or if you would like to help with
this work that would be great.
