无法从SOAP响应中检索值

Question

当我在createSOAPResponse中打印响应时，我确实得到了正确的响应体，但我没有得到实际值。我将获得一个像<xsd:element name="Incident_Number" type="xsd:string"/>这样的节点元素，但没有相关的值。我是新来的。我错过了任何步骤吗？

为了清晰起见，我已经包含了我班级的完整源代码：

 public class RemedySOAPService {

    /**
     * @param args
     * @throws Exception
     */
    public static void main(String[] args) throws Exception {

        // Establish SOAP Connection
        SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
        SOAPConnection soapConnection = soapConnectionFactory.createConnection();

        // Create SOAP Request
        String namespaceURI = "XXX";
        SOAPMessage soapResponse = soapConnection.call(createSOAPRequest(), namespaceURI);

        // Create SOAP Response
        createSOAPResponse(soapResponse);

        // Close Connection
        soapConnection.close();

    }

    /**
     * @param soapResponse
     * @throws Exception
     */
    private static void createSOAPResponse(SOAPMessage soapResponse) throws Exception {
        TransformerFactory transformerFactory = TransformerFactory.newInstance();
        Transformer transformer = transformerFactory.newTransformer();
        Source sourceContent = soapResponse.getSOAPPart().getContent();
        System.out.println("SOAP Response:");
        StreamResult result = new StreamResult(System.out);
        transformer.transform(sourceContent, result);
    }

    /**
     * @return soapMessage
     * @throws Exception
     */
    private static SOAPMessage createSOAPRequest() throws Exception {
        MessageFactory messageFactory = MessageFactory.newInstance();

        // Create SOAP Message
        SOAPMessage soapMessage = messageFactory.createMessage();

        /*<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="XXX">
           <soapenv:Header>
              <urn:AuthenticationInfo>
                 <urn:userName>XXX</urn:userName>
                 <urn:password>XXX</urn:password>

              </urn:AuthenticationInfo>
           </soapenv:Header>
           <soapenv:Body>
              <urn:HelpDesk_QueryList_Service>
                 <urn:Qualification>XXX</urn:Qualification>
              </urn:HelpDesk_QueryList_Service>
           </soapenv:Body>
        </soapenv:Envelope>*/

        // Create SOAP Part
        SOAPPart soapPart = soapMessage.getSOAPPart();

        // Set Constants
        String xmlns = "XXX";
        String username = "XXX";
        String password = "XXX";
        String qualification = "XXX";

        // Create SOAP Envelope
        SOAPEnvelope envelope = soapPart.getEnvelope();
        envelope.addNamespaceDeclaration("urn", xmlns);

        // Create SOAP Header
        SOAPHeader soapHeader = envelope.getHeader();

        // Create SOAP Element for AuthenticationInfo
        SOAPElement authInfoElem = soapHeader.addChildElement("AuthenticationInfo", "urn");

        // Create SOAP ChildElements for userName and password
        SOAPElement usernameChild = authInfoElem.addChildElement("userName", "urn");
        SOAPElement passwordChild = authInfoElem.addChildElement("password", "urn");

        // Assign values to SOAP ChildElements
        usernameChild.addTextNode(username);
        passwordChild.addTextNode(password);

        // Create SOAP Body
        SOAPBody soapBody = envelope.getBody();
        SOAPElement bodyElem = soapBody.addChildElement("HelpDesk_QueryList_Service", "urn");
        createElementAndSetText(bodyElem, "Qualification", qualification);

        // Create MimeHeaders
        String namespaceURI = "XXX";
        MimeHeaders headers = soapMessage.getMimeHeaders();
        headers.addHeader("SOAPAction", namespaceURI + "/XXX");

        // Save Request
        soapMessage.saveChanges();

        // Print the Request Message
        printSOAPRequest(soapMessage);

        return soapMessage;
    }

    /**
     * @param parent
     * @param element
     * @param text
     * @return
     * @throws SOAPException
     */
    private static SOAPElement createElementAndSetText(SOAPElement parent, String element, String text)
            throws SOAPException {
        SOAPElement child = parent.addChildElement(element, "urn");
        child.addTextNode(text);

        return child;
    }

    /**
     * @param soapMessage2
     * @throws SOAPException
     * @throws IOException
     */
    private static void printSOAPRequest(SOAPMessage soapMessage) throws SOAPException, IOException {
        System.out.print("SOAP Request:");
        System.out.println();
        soapMessage.writeTo(System.out);
        System.out.println();
        System.out.println();
    }

}

我的目标是收集从SOAP响应返回的列表，并在第二个操作中使用它们。但是，如果它们没有出现，我如何从该元素中提取值？

我已在SoapUI中测试过，所以我确信请求和响应是正确的。我在构建客户端时遇到了麻烦。
