前提条件:

1.官网下载jax-ws 网址:http://jax-ws.java.net

2.jdk版本1.5以上

1.新建一个web工程:jaxwsWeb,复制官网下载下来的jax-ws的lib中jar文件到WEB-INFO/lib

2.新建类:com.it.server.TimerCheck

package com.it.server;

import java.text.SimpleDateFormat;
import java.util.Date;

import javax.jws.WebMethod;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import javax.jws.soap.SOAPBinding.Style;


@WebService
@SOAPBinding(style = Style.RPC)
public class TimerCheck {
	@WebMethod
	public String getNowTime() {
		System.out.println("==============>>>>web server invoke success!");
		SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
		return sdf.format(new Date());
	}
}

web.xml:

sun-jaxws.xml:

<endpoints xmlns='http://java.sun.com/xml/ns/jax-ws/ri/runtime'
	version='2.0'>
	<endpoint name='annotations' implementation='com.it.server.TimerCheck'
		url-pattern='/nowtime' />
</endpoints>

Web 服务

6.现在可以得到WSDL文件了,有了wsdl文件即可以生成客户端代码进行调用了
