Hi , Iam developing webservice using Jbossws. I have a problem acessing webservice methods. All the methods return a type of string or void. These methods when invoked gives me the following exception : 17:48:21,080 ERROR [SOAPFaultExceptionHelper] SOAP request exception javax.xml.rpc.JAXRPCException: Cannot create or send response message at org.jboss.ws.server.ServiceEndpoint.postProcessResponse(ServiceEndpoint.java:311) at org.jboss.ws.server.ServiceEndpoint.handleRequest(ServiceEndpoint.java:236) at org.jboss.ws.server.ServiceEndpointServlet.doPost(ServiceEndpointServlet.java:120) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) at javax.servlet.http.HttpServlet.service(HttpServlet.java:810) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:252) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:178) at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:175) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:524) at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:74) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:126) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:105) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:107) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:148) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:869) at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:664) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:527) at org.apache.tomcat.util.net.MasterSlaveWorkerThread.run(MasterSlaveWorkerThread.java:112) at java.lang.Thread.run(Thread.java:534) Caused by: org.jboss.xb.binding.JBossXBRuntimeException: Neither getter nor field where found for defaultAssertionStatus in class java.lang.ClassL at org.jboss.xb.binding.MappingObjectModelProvider$FieldToElementMapping.(MappingObjectModelProvider.java:368) at org.jboss.xb.binding.MappingObjectModelProvider.mapFieldToElement(MappingObjectModelProvider.java:71) at org.jboss.ws.jaxb.JAXBMarshallerImpl.marshal(JAXBMarshallerImpl.java:149) at org.jboss.ws.jaxrpc.encoding.JAXBSerializer.serialize(JAXBSerializer.java:100) at org.jboss.ws.soap.SOAPContentElement.getXMLFragment(SOAPContentElement.java:172) at org.jboss.ws.soap.SOAPContentElement.expandToDOM(SOAPContentElement.java:844) at org.jboss.ws.soap.SOAPContentElement.getChildNodes(SOAPContentElement.java:761) at org.jboss.util.xml.DOMWriter.printInternal(DOMWriter.java:211) at org.jboss.util.xml.DOMWriter.printInternal(DOMWriter.java:270) at org.jboss.util.xml.DOMWriter.printInternal(DOMWriter.java:270) at org.jboss.util.xml.DOMWriter.print(DOMWriter.java:186) at org.jboss.util.xml.DOMWriter.printNode(DOMWriter.java:135) at org.jboss.ws.server.ServiceEndpoint.postProcessResponse(ServiceEndpoint.java:305) Any help on this would be really helpful and highly appreciated.
