Has anyone used the eclipse modeling framework in the spring osgi environment?

I generated some code with EMF and trying to use it in a Virgo-Server.

I can start the generated bundle but other bundles have problem with it. They end with a missing constraint exception.

The only thing I see is that the manifest isn't in the same position: the generated code doesn't have the maven structure. META-INF is just in the root directory.

Any idea? Thanks!
