Hi,
While going through the CDO/Hibernate Store tutorial, I came across the following error. It happens when "transaction.commit()" gets executed. I am using CDO version 4.1.0. Has anyone come across a similar issue? Are there any pointers/suggestions that could help me fix this issue. I have looked through the forum, but I haven't found anything helpful.

Hi Jim,
Just for my curiosity (and to update the CDO hibernate store wiki), what did you miss or change to get this working?

Hi,
I'm using the same tutorial (http://wiki.eclipse.org/CDO/Hibernate_Store/Tutorial) and have the same exception:
Neeraj Bhusare wrote on Mon, 02 July 2012 04:04
[ERROR] Rollback in HibernateStore: org.hibernate.MappingException: Unknown entity: org.eclipse.emf.cdo.internal.common.revision.CDORevisionImpl
I've done all suggestions on this thread and I'm still stuck with this exception.
I've tried two SGBD (mysql and H2DB), two JDK (1.5, 1.7), I've added org.eclipse.emf.ecore.change to client project dependencies, and disabled teneo.mapping.persistence_xml without any effects.
With JDK 1.5, I can't launch the server, I get an exception: java.lang.UnsupportedClassVersionError: Bad version number in .class file.
I think one of my plug-in is not compatible with 1.5, but I've not investigated.
Without Hibernate Store, the QuickStartTest is working.
The strangest thing is if I run the HibernateQueryTest on an empty database, the testSimpleQueries pass, not the others. If I run it a second time in the same database, the same test give me this exception :

Hi,
I changed the launch configuration and for mysql now use the MysqlInnodb5 dialect (all pushed to the cdo4.2 git
repository). So hopefully this all works better now.
The absence of a log4j.properties should normally not result in a not working system, only a few additional lines in the
log. The cdo example hibernate server launch has a log4j.debug set.
