I think it is difficult to proceed this way as I am exposing a EJB as a Web Service. So whatever exception I throw from my Web Service is converted to javax.ejb.EJBException and hence restricting me to customize the contents of SOAPFault. I would be glad if somebody can suggest me some solution, but I think JBoss implementation needs to improve on this.
