WebService - Client调用(RPC)

采用的免费webservice接口:

http://ws.webxml.com.cn/WebServices/WeatherWS.asmx?wsdl

客户端代码如下:

package com.web.hh.constroller;

import javax.xml.namespace.QName;

import org.apache.axis2.AxisFault;
import org.apache.axis2.addressing.EndpointReference;
import org.apache.axis2.client.Options;
import org.apache.axis2.rpc.client.RPCServiceClient;
import org.apache.axis2.transport.http.HTTPConstants;

public class ClientWeatherRPC {
    /* * 第三种方式,RPC */
    public static void main(String[] args) throws AxisFault {
        //使用RPC方式调用WebService         
        RPCServiceClient serviceClient = new RPCServiceClient(); 
        Options options = serviceClient.getOptions(); 
//        options.setExceptionToBeThrownOnSOAPFault(false); 
        options.setSoapVersionURI(org.apache.axiom.soap.SOAP12Constants.SOAP_ENVELOPE_NAMESPACE_URI); 
        options.setProperty(HTTPConstants.CHUNKED, "false");
        //指定调用WebService的URL    
        EndpointReference targetEPR = new EndpointReference("http://ws.webxml.com.cn/WebServices/WeatherWS.asmx?wsdl"); 
        options.setTo(targetEPR); 
        options.setAction("http://WebXml.com.cn/getWeather"); 

        //指定方法的参数值    
        Object[] opAddEntryArgs = new Object[] {"昌平",""}; 

        //指定要调用的方法及WSDL文件的命名空间    
        QName opAddEntry = new QName("http://WebXml.com.cn/", "getWeather"); 
        //调用法并输出该方法的返回值    
//        System.out.println(serviceClient.invokeBlocking(opAddEntry, opAddEntryArgs)); 
        Object[] result=serviceClient.invokeBlocking(opAddEntry, opAddEntryArgs, new Class[]{String.class}); 
        for (Object object : result) { 
            System.out.println(object.toString()); 
        } 
    }
}

运行抛异常:
