Re: [eclipselink-users] Re: rcp, osgi, and dynamic weaving

In OSGi, dynamic weaving will be enabled if you have the org.eclipse.persistence.jpa.equinox.weaving and org.eclipse.persistence.jpa.equinox bundles deployed. If you do not have those bundles deployed, we cannot weave dynamically as we do not have the necessary classloader hooks.

If you are interested in getting EclipseLink running I'd love to help you out. The first thing we should do is figure out whether the issue you are seeing is related to weaving behavior, caching behavior, or OSGi. If the objects are weaved, in your debugger, you will see a number of new variables, with names starting with "_persistence". If you do not see those variables, there is something else going on.

Please let me know if you you'd like some help getting EclipseLink working,

Thanks for your offer Tom. I will come back to it when I start working on the app again. btw: Will EclipseLink offer dynamic adding/removing of Entities to the EntityManager during runtime? In OSGi I would like to add and remove new Entities to the running system, without restarting the app. Dynamic-JPA allows that to a certain degree. With Hibernate I wrote myself a little helper that recreated the EM each time the bundle configuration changed. But I was under the impression JPA would already do that, which it does not, to my surprise.
