SOAP消息在接收端出现两次

Question

我有一个设备会按时间间隔向我发送数据，例如5分钟。因此，对于每个数据，我调用以下函数通过webservice将数据发送到接收服务器。一切正常，数据出现两次的唯一问题。我已经彻底检查了每次只调用一次而不是两次的数据。发送每个数据后还有什么问题需要重置或调整？

private static void sendData(String dID,String message) throws Exception {

        try
           {
            SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
            SOAPConnection soapConnection = soapConnectionFactory.createConnection();
            String url = "http://**********/webservice.asmx?WSDL";
            SOAPMessage soapACK = soapConnection.call(createSOAPIncoming(dID,message), url);
            printSOAPINCOMING(soapACK,message);
           }
           catch (Exception e)
           {
                 e.printStackTrace();
                 System.err.println(e.toString());
           }

   }
   private static  SOAPMessage createSOAPIncoming(String dID,String message) throws Exception {
        MessageFactory messageFactory = MessageFactory.newInstance();
         SOAPMessage soapMessage = messageFactory.createMessage();
         SOAPPart soapPart = soapMessage.getSOAPPart();

         String serverURI = "http://*******";

         // SOAP Envelope
         SOAPEnvelope envelope = soapPart.getEnvelope();
         SOAPBody body = envelope.getBody();
         SOAPBodyElement element = body.addBodyElement(envelope.createName("receiveData","", "http://*******"));
         element.addChildElement("pt").addTextNode("****");
         element.addChildElement("sn").addTextNode(dID);         
         element.addChildElement("contents").addTextNode(message);
         MimeHeaders headers = soapMessage.getMimeHeaders();
         headers.addHeader("SOAPAction", "http://********");


         soapMessage.saveChanges();

         /* Print the request message */
         System.out.print("\n\n Request SOAP Message To ACK FOR  = ");
         soapMessage.writeTo(System.out);
         System.out.print("\n\n After Print  = ");
         System.out.println();

         return soapMessage;
    }
   private static  void printSOAPINCOMING(SOAPMessage soapResponse,String message) throws Exception {
        TransformerFactory transformerFactory = TransformerFactory.newInstance();
        Transformer transformer1 = transformerFactory.newTransformer();
        Source sourceContent1 = soapResponse.getSOAPPart().getContent();
        System.out.print("\nResponse SOAP Message = \n");
        StreamResult result1 = new StreamResult(System.out);        
        transformer1.transform(sourceContent1, result1);
       //Connection dbconn = null;

       //Statement stat = null;
         //ResultSet rsOC1 = null;
        Source sourceContent = soapResponse.getSOAPPart().getContent();
        System.out.println("\n\nPrint the soap response:"+ soapResponse.getSOAPPart().getContent());
      TransformerFactory tf = TransformerFactory.newInstance();  
      Transformer transformer = tf.newTransformer();  
      DOMResult result = new DOMResult();  
      transformer.transform(sourceContent, result);  
      Document doc = (Document) result.getNode();

         String tag = "dResponse";

         NodeList list  = doc.getElementsByTagName(tag);
        // String responseTag = itemTitleNode.getFirstChild().getNodeValue();
         Element e = ((Element) list.item(0));
         Element eElement = (Element) e.getChildNodes();

         //System.out.println("\nCurrent Element :" + e.getNodeName());
         String reponseAnswer = eElement.getElementsByTagName("receiveResult").item(0).getTextContent();
         System.out.println("\nreposne result :" + reponseAnswer);

         if(reponseAnswer.equals("SUCCESS"))
         {




         }
