创建第一个WebService程序   1.首先创建实现类IMyServicepackage org.aa;import javax.jws.WebService;/*SEI(Service EndPoint Interface) *SIB(Service Implemention Bean) *在这个例子中IMyService就是SEI，即服务实现的接口，MyServiceImpl就是SIB，即服务实现的Bean  * */@WebService()public interface IMyService {//相加接口public int add(int a ,int b);//相减接口public int minus(int a , int b);}   2.创建IMyService接口的实现类MyServiceImplpackage org.aa;import javax.jws.WebService;//配置好我的接口@WebService(endpointInterface="org.aa.IMyService")//实现IMyService接口public class MyServiceImpl implements IMyService {@Overridepublic int add(int a, int b) {System.out.println(a + "+" + b + "=" + (a+b));return a+b;}@Overridepublic int minus(int a, int b) {System.out.println(a + "-" + b + "=" + (a-b));return a-b;}}   3.创建WebService服务MyServicepackage org.aa;import javax.xml.ws.Endpoint;public class MyServer {public static void main(String[] args){//首先确定一个在网上发布的地址String address = "http://localhost:8888/ns";//发布一下,两个参数，前一个是在网上发布的地址，后一个为要发布接口的实现类Endpoint.publish(address,new MyServiceImpl());}}   4.出现了这个错误   Exception in thread "main" com.sun.xml.internal.ws.model.RuntimeModelerException: runtime modeler error: Wrapper class org.aa.jaxws.Add is not found. Have you run APT to generate them?at com.sun.xml.internal.ws.model.RuntimeModeler.getClass(RuntimeModeler.java:256)at com.sun.xml.internal.ws.model.RuntimeModeler.processDocWrappedMethod(RuntimeModeler.java:567)at com.sun.xml.internal.ws.model.RuntimeModeler.processMethod(RuntimeModeler.java:514)at com.sun.xml.internal.ws.model.RuntimeModeler.processClass(RuntimeModeler.java:341)at com.sun.xml.internal.ws.model.RuntimeModeler.buildRuntimeModel(RuntimeModeler.java:227)at com.sun.xml.internal.ws.server.EndpointFactory.createSEIModel(EndpointFactory.java:308)at com.sun.xml.internal.ws.server.EndpointFactory.createEndpoint(EndpointFactory.java:174)at com.sun.xml.internal.ws.api.server.WSEndpoint.create(WSEndpoint.java:420)at com.sun.xml.internal.ws.api.server.WSEndpoint.create(WSEndpoint.java:439)at com.sun.xml.internal.ws.transport.http.server.EndpointImpl.createEndpoint(EndpointImpl.java:208)at com.sun.xml.internal.ws.transport.http.server.EndpointImpl.publish(EndpointImpl.java:138)at com.sun.xml.internal.ws.spi.ProviderImpl.createAndPublishEndpoint(ProviderImpl.java:92)at javax.xml.ws.Endpoint.publish(Endpoint.java:170)at org.aa.MyServer.main(MyServer.java:10)原因：JDK1.6早起版本对这个类型的支持有bug，所以报错。解决办法：只要将JDK升级到1.6.0_22（包括这个版本）以后，再设置一下MyEclipse默认的jdk就解决问题了，其他的办法不           好解决。   5.创建一个类TestClient调用WebService提供的服务(必须注意测试运行TestClient时必须把MyService服务运行起来)package org.aa;import java.net.MalformedURLException;import java.net.URL;import javax.xml.namespace.QName;import javax.xml.ws.Service;public class TestClient {public static void main(String[] args){try {URL url = new URL("http://localhost:8888/ns?wsdl");//new QName两个参数，第一个是目标命名空间即targetNamespace="http://aa.org/"中的http://aa.org///另一个是本地WebService提供的名称即name="MyServiceImplService"中的MyServiceImplServiceQName sname = new QName("http://aa.org/","MyServiceImplService");//创建Service服务Service service = Service.create(url,sname);//得到IMyService接口IMyService ms = service.getPort(IMyService.class);System.out.println(ms.add(1, 2));} catch (MalformedURLException e) {// TODO Auto-generated catch blocke.printStackTrace();}}}
