Thanks for the reply Lance,

I tried openJPA with just one process. When ever I execute the process,
irrespective of database, Ode throws NPE at BpelProcess.java(Line 429).
So I switched to Hibernate. My goal is to make Ode work with Oracle as
data store, and I couldn't able to make it to work due to dead lock
issues.
That's why I'm interested in moving to openJPA. I will start looking at
the areas you specified, as I get time.

Thank you
Raja

Subject: Re: Working version of Ode with openJPA

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.

Lance
