SAAJ客户端访问WebService

服务端：

package cn.itcast.jdk16ws.service;

import javax.jws.WebMethod;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import javax.xml.ws.Endpoint;

@WebService(serviceName="HelloWorldWS",targetNamespace="http://www.itcast.cn")
@SOAPBinding(style=SOAPBinding.Style.RPC)
public class HelloWorldService {
	@WebMethod
	public String sayHello(String name){
		System.out.println(name);
		return "hello " + name;
	}
	
	@WebMethod
	public String sayWelcome(String name){
		System.out.println(name);
		return "welcome " + name;
	}
	
	public static void main(String... args){
		Endpoint.publish("http://localhost:7070/mywebservice",new HelloWorldService());
	}
}
