httpTransport.call（SOAP_ACTION，envelope）;这一行给出了java.io.ioException是什么原因

Question

我有这个错误：

java.io.ioException

当我执行此行

时

httpTransport.call(SOAP_ACTION, envelope);

是什么原因......？有人可以帮帮我吗？

我从昨天起就一直在尝试这个，但我仍然失败了。

谢谢！

SoapObject object=new SoapObject(NAMESPACE, METHOD_NAME);
        object.addProperty("data", "123");// tis value u wil get frm web service it may change      
         envelope=new SoapSerializationEnvelope(SoapEnvelope.VER11);
         envelope.dotNet=true;
         envelope.setOutputSoapObject(object);
         try {
             HttpTransportSE htp=new HttpTransportSE(URL);
             htp.call(SOAP_ACTION,envelope);
             SoapPrimitive resultString=(SoapPrimitive) envelope.getResponse();
            String server_acknowledgement=resultString.toString();
            } 
         catch (Exception e) {
            // TODO: handle exception
             exceptionArise=true;
             e.printStackTrace();
        }
