I am developing a web service client to consume a web service that returns an Object not a String. When I make the webservice return a String it works perfectly, when I switch to a Object then it throws this exception: org.xml.sax.SAXException: Deserializing parameter 'result': could not find deserializer for type {http://ericsson.webservice.ems.com.br/EricssonMockingWebService/types}SendResponse at org.apache.axis.message.RPCHandler.onStartChild(RPCHandler.java:330) at org.apache.axis.encoding.DeserializationContextImpl.startElement(DeserializationContextImpl.java:1188) at org.apache.axis.message.SAX2EventRecorder.replay(SAX2EventRecorder.java:244) at org.apache.axis.message.SOAPElementAxisImpl.publishToHandler(SOAPElementAxisImpl.java:1407) at org.apache.axis.message.RPCElement.deserialize(RPCElement.java:263) at org.apache.axis.message.RPCElement.getParams(RPCElement.java:397) at org.apache.axis.client.Call.invoke(Call.java:2652) at org.apache.axis.client.Call.invoke(Call.java:2524) at org.apache.axis.client.Call.invokeInternal(Call.java:1976) at org.apache.axis.client.Call.invoke(Call.java:1917) at org.jboss.webservice.client.CallImpl.invoke(CallImpl.java:175) at org.apache.axis.client.AxisClientProxy.invoke(AxisClientProxy.java:251) at $Proxy145.send(Unknown Source) at br.com.ouvi.ems.gw.ericssonipx.ejb.EricssonIPXWebServiceHelperEJB.sendSms(EricssonIPXWebServiceHelperEJB.java:62) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.jboss.invocation.Invocation.performCall(Invocation.java:345) at org.jboss.ejb.StatelessSessionContainer$ContainerInterceptor.invoke(StatelessSessionContainer.java:214) at org.jboss.resource.connectionmanager.CachedConnectionInterceptor.invoke(CachedConnectionInterceptor.java:185) at org.jboss.ejb.plugins.StatelessSessionInstanceInterceptor.invoke(StatelessSessionInstanceInterceptor.java:113) at org.jboss.webservice.server.ServiceEndpointInterceptor.invoke(ServiceEndpointInterceptor.java:51) at org.jboss.ejb.plugins.CallValidationInterceptor.invoke(CallValidationInterceptor.java:48) at org.jboss.ejb.plugins.AbstractTxInterceptor.invokeNext(AbstractTxInterceptor.java:105) at org.jboss.ejb.plugins.TxInterceptorCMT.runWithTransactions(TxInterceptorCMT.java:316) at org.jboss.ejb.plugins.TxInterceptorCMT.invoke(TxInterceptorCMT.java:149) at org.jboss.ejb.plugins.SecurityInterceptor.invoke(SecurityInterceptor.java:128) at org.jboss.ejb.plugins.LogInterceptor.invoke(LogInterceptor.java:191) at org.jboss.ejb.plugins.ProxyFactoryFinderInterceptor.invoke(ProxyFactoryFinderInterceptor.java:122) at org.jboss.ejb.SessionContainer.internalInvoke(SessionContainer.java:624) at org.jboss.ejb.Container.invoke(Container.java:854) at org.jboss.ejb.plugins.local.BaseLocalProxyFactory.invoke(BaseLocalProxyFactory.java:413) at org.jboss.ejb.plugins.local.StatelessSessionProxy.invoke(StatelessSessionProxy.java:82) at $Proxy143.sendSms(Unknown Source) My client looks like this. public SendResponse sendSms(String smsMessage) throws WebserviceException { SendResponse sendSmsResponse; sendSmsResponse = null; try { System.out.println("Contacting webservice at http://localhost:8080/ws4ee/services/EricssonMockingWebService?wsdl"); URL url = new URL("http://localhost:8080/ws4ee/services/EricssonMockingWebService?wsdl"); QName qname = new QName("http://ericsson.webservice.ems.com.br", "EricssonMockingWebService"); ServiceFactory factory = ServiceFactory.newInstance(); Service service = factory.createService(url, qname); EricssonMockingWebServiceEndpoint endpoint = (EricssonMockingWebServiceEndpoint) service.getPort(EricssonMockingWebServiceEndpoint.class); System.out.println("output:" + endpoint.send("blablabalblabl")); } catch (Exception ex) { logger.error("Exception doing sms request for IPX: " + ex.getMessage(), ex); throw new WebserviceException(ex.getMessage(), ex); } return sendSmsResponse; } The exception is thrown from the line: System.out.println("output:" + endpoint.send("blablabalblabl")); I am guessing I am missing a deserializer class that is produced by the wstools, but I haven't been able to find out which yet. Anybody experienced the same problem? Best regards, Eivind View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4263600#...
