Resolution

  • Need to use right redhat version of xerces.jar(xercesImpl-2.9.1.redhat-5.jar) in the jboss-depoyment-structure.xml.

Root Cause

  • By using of old version of xerces jar which is the root causes of the issue.

Diagnostic Steps

  • User is migrated to EAP 6.2.0 from EAP 4.2.2. and using hibernate2
  • In hibernate.cfg.xml file, there is not a element with liferay . This is in the liferay jars deployed in ear
