JPA with OSGi DS example

Question

I am trying to figure out an example of JPA(containing an example of Student Entity, with name and class) using Eclipselink & Derby. I am able to do it in Java EE but I can't figure out a way to do it simply in OSGi using Declarative Services.

Can anyone share some info on any such examples which uses JPA with OSGi DS?

Some of the examples I have gone through are here, but these examples use getReference or getTracker however I don't want to use them.

Thank you.

You can take a look at the OSGi enRoute project's tutorial. This is still work in progress but in phase 10 it actually uses JPA, transactions, etc.

In the master branch there is a PDF that describes the tutorial in detail, step by step. Each step is a branch so you can look at the 10-jpa branch. It uses bndtools.

This is work in progress but it should give you a good idea.
