发送Post类型XML请求Web服务Java - 失败响应

Question

我正在执行以下java代码，使用java将XML请求发送到webservice URL。我查看了这个链接来创建我的脚本。 作为反应，我正在失败。我做了一个XML字符串的打印。 XML正确形成，没有任何问题。 我需要知道我哪里出错了，此时任何指导都会很棒。

    HttpURLConnection connection = null;  
     try {
      //Create connection
    String targetURL="https://XXXXXX.html";
    System.out.println(targetURL);
    String urlParameters="<?xml version=\"1.0\" encoding=\"iso-8859-1\"?  >\r\n<request>\r\n <control>\r\n  <senderid>XXXX</senderid>\r\n  <password>XXXX</password>\r\n  <controlid>ControlIdHere</controlid>\r\n  <uniqueid>false</uniqueid>\r\n  <dtdversion>3.0</dtdversion>\r\n </control>\r\n <operation>\r\n  <authentication>\r\n   <login>\r\n    <userid>XXX</userid>\r\n    <companyid>XXXX</companyid>\r\n    <password>XXXX</password>\r\n   </login>\r\n  </authentication>\r\n\r\n<content>\r\n <function controlid=\"testControlId\">\r\n  <readByQuery>\r\n    <object>CUSTOMER</object>\r\n    <query/>\r\n  </readByQuery>\r\n </function>\r\n</content>\r\n </operation>\r\n</request>";

      connection.setRequestMethod("POST");

      connection.setUseCaches (false);

      DataOutputStream wr = new DataOutputStream (

      wr.writeBytes (urlParameters);
      wr.flush ();
      wr.close ();

      StringBuffer response = new StringBuffer(); 
      while((line = rd.readLine()) != null) {

        System.out.println(line);
        response.append('\r');
      }
      rd.close();
      return response.toString();

    } catch (Exception e) {

      e.printStackTrace();
      return null;

    } finally {

      if(connection != null) {
        connection.disconnect(); 
      }
    }
  }
