Eclipse + Java SE 6 快速建立web service

from https://www6.software.ibm.com/developerworks/cn/education/webservices/ws-eclipse-javase1/section2.html

1. new Java Project

   make sure JRE is JAVA SE 6

2. create POJO

package com.myfirst.wsServer;import Javax.jws.WebService;@WebServicepublic class SayHello { private static final String SALUTATION = "Hello"; public String getGreeting( String name ) {  return SALUTATION + " " + name; }}

3. 用 wsgen 產生中間檔案

   wsgen -cp ./bin -keep -s ./src -d ./bin com.myfirst.wsServer.SayHello

4. web service publish

package com.myfirst.wsServer;import Javax.xml.ws.Endpoint;public class RunService { /** * @param args */     public static void main(String[] args) {  System.out.println("SayHello Web Service started.");  Endpoint.publish("http://localhost:8080/wsServerExample", new SayHello()); }}

5. run as java applicaiton 啟動服務

6. 通過 http://localhost:8080/wsServerExample?wsdl 查看wsdl檔案內容

7. Eclipse 提供了 Run > Launch the Web Services Explorer 來測試web service. 根據WSDL檔案就可以了。
