我正在应用程序中工作，希望我需要调用肥皂网络服务。为此，我正在使用 SAAJ。为了测试，我制作了以下方法来调用服务。该服务返回一个作为输入接收的字符串。我的问题是该服务被调用但它没有接收输入参数。谁能给我一个关于如何解决这个问题的想法？2. 我还有一个问题，我该如何调用以对象为输入的服务？3. SAAJ 是创建远程客户端调用肥皂服务的最佳解决方案吗？谢谢

 public void invokeExtractMetadata(Service service,String path) throws Exception  {
     System.out.println("invoke"); 
    QName serviceName = new QName(service.namespace, service.serviceName);
    QName portName =  new QName(service.namespace, service.portType);

    String  endpointAddress =service.endPointAddress;
    javax.xml.ws.Service myService = javax.xml.ws.Service.create(serviceName);

    myService.addPort(portName, SOAPBinding.SOAP11HTTP_BINDING, endpointAddress);



    Dispatch<SOAPMessage> dispatch = myService.createDispatch(portName, SOAPMessage.class, javax.xml.ws.Service.Mode.MESSAGE);


    BindingProvider bp = (BindingProvider) dispatch; //Use Dispatch as BindingProvider

    MessageFactory factory =  ((SOAPBinding) bp.getBinding()).getMessageFactory();

    SOAPMessage request = factory.createMessage();

    // Request Header
    SOAPHeader header = request.getSOAPHeader();

    // Request Body
    SOAPBody body = request.getSOAPBody();

    // Compose the soap:Body payload
    QName payloadName =   new QName(service.namespace,service.inMsgTag );
    SOAPBodyElement payload = body.addBodyElement(payloadName);

    QName name = new QName("pathT");
    SOAPElement message = payload.addChildElement(name);
    message.addTextNode(path);






    SOAPMessage reply = null; 
    //Invoke Endpoint Operation and read response
    reply = dispatch.invoke(request);
                    //process the reply

    body = reply.getSOAPBody();
    QName responseName =   new QName(service.namespace, service.outMsgTag);
    SOAPBodyElement bodyElement = (SOAPBodyElement)body.getChildElements(responseName).next();

    QName elementName = new QName("", "return");

    Iterator t =bodyElement.getChildElements(elementName);
     System.out.println("tt");


     while(t.hasNext()){
         SOAPBodyElement bodyElementTest = (SOAPBodyElement)t.next();
         String valeur = bodyElementTest.getValue();
         System.out.println("valeur"+valeur);

     }

     }
