javax.xml.ws.soap.SOAPFaultException when calling web service

Question

I've created a Web Service Client in eclipse using Apache CXF 2.x from the following WSDL:

https://test.timbrado.com.mx/cfdi/wstimbrado.asmx?WSDL

When doing the web service call I get the following error stacktrace (The server can't process the request ---> Reference to object not established as an object instance):

javax.xml.ws.soap.SOAPFaultException: El servidor no puede procesar la solicitud. ---> Referencia a objeto no establecida como instancia de un objeto.

The call I am doing it this way:

ObjectFactory of = new ObjectFactory();
    AuthenticationHeader ah = of.createAuthenticationHeader();
    ah.setUserName(cfdi.getUsuarioPAC());
    ah.setPassword(cfdi.getPasswordPAC());
    JAXBElement<AuthenticationHeader> jah = of.createAuthenticationHeader(ah);

    ServicioTimbradoPruebas stp = new ServicioTimbradoPruebas();
    ServicioTimbradoPruebasSoap stpSoap = stp.getServicioTimbradoPruebasSoap();

    try{
        WSBindingProvider bp = (WSBindingProvider)stpSoap;
        Header hdr = Headers.create((JAXBRIContext) JAXBContext.newInstance(AuthenticationHeader.class),jah);
        bp.setOutboundHeaders(hdr);
    }catch(Exception ex){
        ex.printStackTrace();
        error = "Error en webservice ";
    }
    byte [] xmlBytes = cfdi.getXml().getBytes("UTF-8");
    String result = stpSoap.generaTimbre(xmlBytes);

The error I get it in the following line:

String result = stpSoap.generaTimbre(xmlBytes);

Before I was able to do the web service call, but now I am not able to do it and I get the following error. Any suggestions of how I can solve this problem?

I guess this will be not much of an answer, but anyways:

That service is seriously f** up.

For example

<cfdi:xmlBytes>cdi:246460475753</cfdi:xmlBytes>

in

<cfdi:GeneraTimbre>

is optional according to the WSDL contract:

     <s:element name="GeneraTimbre">
        <s:complexType>
           <s:sequence>
              <s:element minOccurs="0" maxOccurs="1" name="xmlBytes" type="s:base64Binary"/>
           </s:sequence>
        </s:complexType>
     </s:element>

(notice the minOccurs="0" !) Yet when you send a message without the optional part, you'll get a soapfault:

 <soap:Body>
      <soap:Fault>
         <faultcode>soap:MustUnderstand</faultcode>
         <faultstring>No se entendió el encabezado SOAP Security.</faultstring>
      </soap:Fault>
   </soap:Body>

As I said in the beginning, this won't be much of an answer, just an advice maybe: try to stay away from so poorly written services. (My guess is that they tried to implement ws-sec, but without the ws-policy framework, which can be done, but will give little or no help at all to the service consumer on how to use it properly)

I know the service is not properly built. But I need to consume this web service as it is required for doing electronic invoices in Mexico. Any help would be appreciated — user1084509, Jul 03 '12 at 14:24
Since they're misusing the whole 'contract' part of the webservice, I think you only have two options: spend a lot of time with trial&error, or contact them to get a working sample... — Gergely Szilagyi, Jul 04 '12 at 12:47
