Gemini JPA for dummies? [message #1453916]

I'm trying to get JPA to work in an OSGi project but I keep getting the following:

org.osgi.framework.BundleException: Could not resolve module: org.eclipse.gemini.jpa [18]
Unresolved requirement: Import-Package: javax.persistence; jpa="2.0"; version="1.1.0"

I've installed "Gemini JPA" and "Gemini DBAccess" from the update sites and I am using Apache Derby as the backend.

I've installed:
EclipseLink Target Components - EclipseLink JPA (2.6.0)
Dali Java Persistence Tools - JPA Support (3.4.0)
Equinox Target Components (3.4.0)
Gemini DBAccess for Derby (1.1.0.RELEASE)
Gemini JPA (1.1.0.RELEASE)

And even after "Add Required Bundles" I'm STILL getting errors regarding:
Import-Package: ... "javax.persistence;jpa="2.0";version="1.1.0" ...

I saw a 4 year old post about "patching gemini" but that surely can't still be the ONLY solution!?!?!?

If the OSGi support was removed from EclipseLink to Gemini JPA, then surely the developers of these 2 projects should be working closely with each other?

My experience with EclipseLink, OSGi JPA and Eclipse Gemini haven't exactly been instilling me with confidence :-/

How am I supposed to configure OSGi, Equinix AND Gemini JPA using the available online resources?

Hi Bill,

Try using Gemini JPA 1.2.0 M1 to work with EclipseLink 2.6.0.
Let me know if you have any problems with it.

Hi all,

I had the same problem like Bill with Version 1.1.0 but with 1.2.0 M1 it worked quite well with a persistence.xml file in the bundle package. Now I want to make the configuration a bit more flexible with the configuration via the configuration admin. I followed the instructions here -> Gemini/JPA/Documentation/OtherTopics#Configuration_Admin and read the configuration file with the apache felix file installer. But it does not work. File name is: org.eclipse.gemini.jpa.punit.cfg. Maybe I took the wrong way?
