This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
The SOAP Fault Exception raised here is due to the mismatch between the Metro jar versions between the Jboss and the web service client code. In this case the web service client was created with Metro 2.0.1 and the Jboss native JAXWS jars were not able to support this.
So we created a new web service client code with Metro 2.2 and copied the essential Metro 2.2 and JAXWS-RI 2.2 jars (webservices-rt.jar, jaxws-api.jar) in the endorsed folder of the Jboss.Also deleted the native jars (Jbossws-native-jaxrpc.jar, Jbossws-native-jaxws-ext.jar, Jbossws-native-jaxws.jar, Jbossws-native-saaj.jar) from the Jboss\lib\endorsed directory. This fixed the issue.
