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

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...
