I fixed it. EnvironmentRefsGroupMetaData should have bound serviceReferences to service-ref element. Now there is a different exception. org.jboss.xb.binding.JBossXBRuntimeException: {http://java.sun.com/xml/ns/javaee}port-component-ref not found as a child of {http://java.sun.com/xml/ns/javaee}service-ref | at org.jboss.xb.binding.sunday.unmarshalling.SundayContentHandler.startElement(SundayContentHandler.java:370) | It seems like the implementation of the ServiceReferenceMetaData is incomplete.
