webService调用一个小疑点,参数用实体类?可另外赠分.

String serviceURL = "http://localhost:8080/Collect/services/IDataService";        Service serviceModel = new ObjectServiceFactory().create(                IDataService.class, null,                "http://localhost:8080/Collect/services/IDataService",                null);        XFireProxyFactory serviceFactory = new XFireProxyFactory();        try {            IDataService service = (IDataService) serviceFactory.create(                    serviceModel, serviceURL);            // 忽略http连接的超时时间,0为不设置超时时间，》=1为超时毫秒数            Client client = Client.getInstance(service);            client.setProperty(CommonsHttpMessageSender.HTTP_TIMEOUT, "0");                        String hello = service.sayHello("admin");            System.out.println("服务器对[张山疯] 的回答是：" + hello);        } catch (MalformedURLException e) {            e.printStackTrace();        }    }
