最近在做一个支付的接口.
因为接口方使用webservice交互. 
我只能去学习了下webservice
现在出了一个很古怪的问题~ 
我在请求他们url的时候, 返回给我找不到控制名错误
Message part refundRequest was not recognized.  (Does it exist in service WSDL?)
请教大神这是怎么回事
上代码
我这边使用的是axis.
requestUrl 是 请求地址
sb.toString是我发过去的报文.
                        Service service=(Service) new Service();
Call call =(Call)service.createCall();
call.setTargetEndpointAddress(requestUrl);
call.setOperationName("refundRequest");
String repose=(String)call.invoke(new Object[] { sb.toString() });

因为现在返回给我找不到操作名.
所以我也不知道到底是我这写错了还是客户方那边有问题?
下面上错误信息
