Datanucleus, JDO and executable jar - how to do it?

Question

I am developing a desktop app with Datanucleus and JDO for embedded H2 database. It all works fine when I run it from Eclipse, but it stops working when I try to make execut

Answer 1

DataNucleus jars are all OSGi-enabled and use a plugin mechanism to identify capabilities, so contain plugin.xml and META-INF/MANIFEST.MF files. These need to be in the same locations as they are in the original DN jars (from the root of the jar). If you unpack and then rejar them up you will need to merge any plugin.xml and META-INF/MANIFEST.MF from the DN jars ... ALL of the information there not just some of it.
