I'll take a detailed look at your code but right away I can see you are
not following the instructions. In the example, all the code is in single
bundle with an Activator that implements
org.osgi.framework.BundleActivator. Your version is using Eclipse
classes. See if you can get the example I describe running then we can
make changes until it breaks. Members of the EclipseLink development team
have got the example running as described.
