[jboss-user] [JBossWS] - Help:Cannot obtain endpoint meta data!

jboss4.2.2+jdk6 @WebService(name="BookWS",targetNamespace="http://net.cjc.ws",serviceName="BookWSService") @SOAPBinding(style= SOAPBinding.Style.RPC) @Stateless public class BookWS { @EJB private AuthorManager am; @WebMethod public List getMyBook(String me) { return am.queryBooks(me); } } and I also configured web.xml to define this endpoint as a servlet. While I deploy this war,the following exception is thrown: ava.lang.NoClassDefFoundError: Could not initialize class com.sun.xml.bind.v2.model.impl.RuntimeModelBuilder at com.sun.xml.bind.v2.runtime.JAXBContextImpl.getTypeInfoSet(JAXBContextImpl.java:422)... But I still can see this web service from jbossws;When I click the related link,the browser says it cannot phrase XML.Another exception is thrown on the console: 01:25:36,750 ERROR [RequestHandlerImpl] Error processing web service request java.lang.IllegalStateException: Cannot obtain endpoint meta data at org.jboss.wsf.stack.jbws.RequestHandlerImpl.handleWSDLRequest(RequestHandlerImpl.java:520) Why?
