I managed to make the CDO Hibernate Store example work - with a Mysql database and with annotations. But as soon as I switch to using the hibernate mapping file, drop the database and try to start the server again, I get
[ERROR] Unable to instantiate default tuplizer [org.eclipse.emf.cdo.server.internal.hibernate.tuplizer.CDOR evisionTuplizer]

As I found out, the cause is that the EPackage http://www.eclipse.org/emf/CDO/examples/company/1.0.0 is not found in CDORevisionTuplizer.initEClass().
Any hint why this happens (and not happens with annotations) would be highly appreciated!
(I'm using the.4.0. version of the org.eclipse.emf.cdo.server.hibernate plugin)

Günther
