　　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);
