Hello,

a hibernate.hbm.xml that I have generated with teneo causes a ClassNotFoundException. The classname within the hibernate.hbm.xml references a class at the impl folder that I have generated with an ecore genmodel before. When I deploy my project as war to JBoss 5.1 I get the error.

My hibernate.hbm.xml

Error:
DEPLOYMENTS IN ERROR:
  Deployment "persistence.unit:unitName=#timetracker-persistence" is in error due to the following reason(s): java.lang.ClassNotFoundException: timetracker.impl.OperatorImpl from BaseClassLoader


Amazingly the server doesn't complain about the other class timetracker.impl.Project.

Does anybody have a hint?

Hi Daniel,
Hmm, I can't really say why this happens (I don't have experience with jboss myself).
