Reason: java.lang.NoClassDefFoundError: org.hibernate.cfg.EJB3DTDEntityResolver
Looks like the this class file is not found in the classpath. What does your compliancetracker.ear and compliancetrackerEjb.jar contain?
You should have this class in server//lib/hibernate-annotations.jar.
(Per default 4.2 installation)
I finally solved the problem and it was simply a deployment of hibernate-annotations.jar. However, some new issues related to JBOSS Seam 1.2.1 and JBOSS 4.2.0 incompatibility have arisen. However I shall put these in a different posting.
