Hi Harald, I have two questions:
1. Are you pre-enhancing your Entity classes? This is a requirement using the base Aries JPA container as load-time weaving cannot be supported in a generic OSGi framework (although some runtimes extend the Aries code to provide this, e.g. Geronimo and WebSphere). 2. Are you listing all of your entity classes in the persistence unit definition and setting <exclude-unlisted-classes>false</exclude-unlisted-classes>? In unmanaged JPA you are supposed to do this (though many providers support scanning in unmanaged environments). In OSGi scanning doesn't work the same way, and is, once again, not supported in the Aries JPA container (though it is provided in WebSphere). Both of these limitations will (hopefully) be lifted in the future, but they will need to rely on features proposed for version 4.3 of OSGi, and so there's not a lot we can do about them at the moment.
