## 服务端代码如下 ##

public interface WeatherInterface {
    	public String queryWeather( String cityName);
    }

import javax.jws.WebService;
    
    @WebService     //@WebService表示该类是一个服务类，需要发布其中的public的方法
    public class WeatherInterfaceImpl implements WeatherInterface {
    
        @Override
        public String queryWeather(String cityName) {
            System.out.println("获取城市名"+cityName);
            String weather="暴雨";    
            return cityName+":"+weather;
        }
    
    }

import javax.xml.ws.Endpoint;
    
    public class WeatherServer {
    
    	public static void main(String[] args) {
    		 Endpoint.publish("http://127.0.0.1:12345/weather", new WeatherInterfaceImpl());
    	}
    
    }

## 客户端 ##

找一个目录，然后打开cmd命令窗口，下载客户端源码

wsimport -s . http://127.0.0.1:12345/weather?wsdl

public class WeatherClient {
    
    	public static void main(String[] args) {
    		// 创建服务视图，视图是从wsdl文件的service标签的name属性获取
    		WeatherInterfaceImplService weatherInterfaceImplService = new WeatherInterfaceImplService();
    
    		// 获取服务实现类，实现类从wsdl文件的portType的name属性获取
    		WeatherInterfaceImpl weatherInterfaceImpl = weatherInterfaceImplService.getPort(WeatherInterfaceImpl.class);
    
    		// 获取查询方法，从portType的operation标签获取
    		String weather = weatherInterfaceImpl.queryWeather("北京");
    
    		System.out.println(weather);
    	}
    
    }

## axis客户端调用webservice ##

import javax.xml.namespace.QName;
    import javax.xml.rpc.ParameterMode;
    
    import org.apache.axis.client.Call;
    import org.apache.axis.client.Service;
    import org.apache.axis.encoding.XMLType;
    
    public class WebserviceClient {
    
    	public static void main(String[] args) throws Exception {
    		String endpoint = "http://127.0.0.1:12345/weather";
    		String targetNamespace = "http://webservice.org/";
    		Service service = new Service();
    		Call call = (Call) service.createCall();
    		call.setTimeout(new Integer(300000));
    		call.setTargetEndpointAddress(new java.net.URL(endpoint));
    		
    		// 调用的方法名
    //		call.setOperationName("queryWeather");
    		call.setOperationName(new QName(targetNamespace,"queryWeather"));
    		call.addParameter("arg0", XMLType.XSD_STRING,ParameterMode.IN);
    //		call.addParameter(new QName(targetNamespace, "cityName"),  
    //                org.apache.axis.encoding.XMLType.XSD_STRING,  
    //                javax.xml.rpc.ParameterMode.IN);
    		
    		String xml = "helloWord";
    		
    		//发起调用  提交的内容为 xml 格式字符串
    		String result = (String) call.invoke(new Object[] {xml});
    		
    		System.out.println(result);
    	}
    
    }
