WEBSERVICE快速入门的示例：
首先定义接口：
package com.whaty.platform.ws.server;import javax.jws.WebService;/** * @className:IMyservice.java * @Desc:定义：SEI service endpoint interface * @author:lizhuang * @createTime:2012-12-21 上午12:57:18 *///JAX-WS注解，表示java api xml for webservice。JDK自带API的XML格式的webservice@WebServicepublic interface IMyservice {int add(int a, int b);int minus(int a, int b);}其次编写实现类：package com.whaty.platform.ws.server;import javax.jws.WebService;/** * @className:MyServiceImpl.java * @Desc:定义：SIB service implemention bean * @author:lizhuang * @createTime:2012-12-21 上午01:01:22 *///endpointInterface指定接入点接口：接口必须存在@WebService(endpointInterface="com.whaty.platform.ws.server.IMyservice")public class MyServiceImpl implements IMyservice {public int add(int a, int b) {System.out.println("a+b="+(a+b));return a+b;}public int minus(int a, int b) {System.out.println("a-b="+(a-b));return a-b;}}最后发布我们的服务，，直接右键运行main方法，如果控制台没报错，多半是发布成功了，否则检查你的代码：package com.whaty.platform.ws.server;import javax.xml.ws.Endpoint;/** * @className:MyServer.java * @Desc:发布服务 * @author:lizhuang * @createTime:2012-12-21 上午01:02:39 */public class MyServer {public static void main(String[] args) {//访问方式：:7777/tudou?wsdlString address=":7777/tudou";Endpoint.publish(address, new MyServiceImpl());}}
浏览器地址栏输入：访问webservice看看是否发布成功【地址后面加上"?wsdl"】：
:7777/tudou?wsdl
浏览器显示如下：

下面我们创建客户端访问：
package com.whaty.platform.ws.client;import java.net.MalformedURLException;import java.net.URL;import javax.xml.namespace.QName;import javax.xml.ws.Service;import com.whaty.platform.ws.server.IMyservice;/** * @className:MyClient.java * @Desc:访问发布的服务 * @author:lizhuang * @createTime:2012-12-21 上午01:23:57 */public class MyClient {public static void main(String[] args) {try {//服务WSDL Document的地址URL url = new URL(":7777/tudou?wsdl");//Qnameqname是qualified name 的简写//2.构成：由名字空间(namespace)前缀(prefix)以及冒号(:),还有一个元素名称构成//由发布的wsdl可知namespace为，QName qname=new QName("","MyServiceImplService");Service service=Service.create(url, qname);IMyservice ms=service.getPort(IMyservice.class);ms.add(1, 4);ms.minus(1, 4);} catch (MalformedURLException e) {e.printStackTrace();}}}控制台打印如下：
a+b=5a-b=-3
