[jboss-user] [Installation, Configuration & Deployment] - How can i get my Castor application work under JBoss4.0.4RC1

Deal All: I have some classes to deal with XML using Castor which are packaged into EJB jar lib.And i have put Castor.jar and xercesImpl.jar into WEB-INFO/lib. But when EJB call my pojo to access Castor library,it will raise java.lang.RuntimeException: Could not instantiate parser org.apache.xerces.parsers.SAXParser: java.lang.ClassCastException: org.apache.xerces.parsers.XML11Configuration at following code: mapping.loadMapping(new InputSource(mappingIn));where mapping is instance of Mapping class in Castor libarary. Anyone can tell me how to resolve this problem?Is it class loading issue or conflict with JBoss library? Thanks!
