　　axisd调用webservice，明明写了参数，但代码调用还是报这个错，问题是参数也需要传namespace

try {
            String endpoint = "http://ws.webxml.com.cn/WebServices/WeatherWS.asmx?wsdl";
            String namespace="http://WebXml.com.cn/";
            String methodName="getSupportCityString";
            // 直接引用远程的wsdl文件
            // 以下都是套路
            Service service = new Service();
            Call call = (Call) service.createCall();
            call.setTargetEndpointAddress(endpoint);
            call.setOperationName(new QName(namespace,methodName));
            call.setReturnType(XMLType.XSD_SCHEMA);
            call.setUseSOAPAction(true);
            //设置soapAction
            String soapAction = "http://WebXml.com.cn/getSupportCityString";
            call.setSOAPActionURI(soapAction);
            call.addParameter(new QName(namespace, "theRegionCode"),
                    XMLType.XSD_STRING,
                    ParameterMode.IN);// 接口的参数
//            call.setReturnType(org.apache.axis.encoding.XMLType.XSD_STRING);// 设置返回类型
            String temp = "31121";
            Schema result = (Schema) call.invoke(new Object[] { temp });
            for (MessageElement messageElement : result.get_any()) {
                System.out.println(messageElement.getAsString());
            }
            // 给方法传递参数，并且调用方法
            System.out.println("result is " + result);
        } catch (Exception e) {
            System.err.println(e.toString());
        }

　　新增参数需要用下面的写法：

call.addParameter(new QName(namespace, "theRegionCode"),
        XMLType.XSD_STRING,
        ParameterMode.IN);
