samples/server is not returning entity/entitycollections in xml

The xml serialization issue observed in RC02 has been fixed in RC03 for samples/tutorial but not for samples/server.

As a result, some scenarios using samples/server and its OSGi version are not working when the client is requesting for XML responses or when not preferring application/json.

Could you apply the same change to samples/server as well. That will fix both the standalone case and the OSGi case.

thanks.
