android 中使用 soap， 发生异常， 不知道哪里 错了?报错

代码如下， 报错是call方法， 我用的是虚拟机，服务器是本机

     public void onClick(View arg0)
     {

      String sayHello = "sayHello";
      String NameSpace = "http://www.zhangboyue.com/";
      String WSDL = "http://localhost/xFireService/services/MyService";
      
      String result = "";
   
      SoapObject request = new SoapObject(NameSpace,sayHello);
   
      request.addProperty("msg", "zhangboyue");
      
      SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
        SoapEnvelope.VER11);
   
      envelope.bodyOut = request;
      envelope.setOutputSoapObject(request);
      envelope.encodingStyle = "UTF-8";
  
      HttpTransportSE ht = new HttpTransportSE(WSDL, 15000);
      ht.debug = true;
 
      try
      {
       ht.call(null, envelope);
       if (envelope.getResponse() != null)
       {
        SoapObject response = (SoapObject) envelope.getResponse();
        result = response.toString();
        Toast.makeText(getActivity(), result, Toast.LENGTH_SHORT).show();
       }
      } catch (IOException e)
      {
       System.out.println("IOException");
      } catch (XmlPullParserException e)
      {
       System.out.println("XmlPullParserException");
      }

下面是log
