Hi, Charles,
Yes, there is a pax-openjpa project.
Looks like it's still in the lab, but it works and I use it.

Thanks very much for your explanation. We are not too much concerned with
scalability as we do intranet apps, but they in fact deal mostly with set
operations as you say.
As you put it, it seems that I should stick with DAO (either JPA based or
not), and/or perhaps any other layer that
Hello list.
I upgraded OpenJPA from 1.2.0 to 1.2.1 and have the following exception.
My environment is MySql 5.0.51 (MyISAM storage manager) and JRE Sun
1.6.0_13-b03. The application works without this exception with OpenJPA
1.2.0.

Hi,
I'll let Pinaki post on the eclipse plugin questions, but I'll take a shot
at the alternate JPA provider question...

Hello again,
I exactly tried this now. But this time, the Error gets even weirder,
cause now I get: java.lang.Integer is incompatible with java.lang.Long,
were honestly NO single Integer is present in both classes. What is JPA
trying to do here?

Hi Charles,
The answer is mixed. We currently don't package OpenJPA as a bundle in the
pure Apache environment, but OpenJPA is packaged as an OSGi bundle when used
as part of the WebSphere JPA solution. So, it is doable... ;-)
I also found this article on Developer Works [1]. Granted, this is

I'm currently trying to use the Eclipse Plugin provided at

JPA is more akin to Model-View-Controller (MVC) programming model where
Model = database record/schema

Thanks for sharing this. In my case, I believe I still need DAO, see
(quoted from [1]:
"...The usage cannot be simpler. The EntityManager will be just injected
to the bean-class...The DAO pattern is actually no more interesting for
general data access, but is still needed to access data from

I've never used the DAO pattern. My homegrown web application framework I
would say is a little "too close to the metal". In trying to learn JPA, I
see this pattern of MyEntity
Hi,
I would like to know if some users have already deployed and used OpenJPA
top of an OSGI server like ServiceMix Kernel (based on Apache Felix, Spring
OSGI and PAX) ?
Is OpenJPA already available as OSGI bundles (I mean MANIFEST file of the
jars have been modified to import or export-package)
