首先感谢熔岩的文章：

1.Eclipse安装上tomcat插件，http://www.eclipsetotale.com/tomcatPlugin.html下载后解压者eclipse的plugin目录

2.建立一个WebService：

package com.garfield.webservice;

import javax.jws.WebService;


/** 
* Java6开发的WebService服务端 
* 
* @author leizhimin 2009-11-16 10:24:13 
*/ 
@WebService 
public class HelloWebservice {
    /** 
     * Web服务中的业务方法 
     * 
     * @return 一个字符串 
     */ 
    public String doSomething(String username) { 
            return username + " is doing something!"; 
    } 
}

3.在Eclipse中新建一个tomcat工程，建立一个Servlet:

package com.garfield.servlet;

import java.io.IOException;

import javax.servlet.GenericServlet;
import javax.servlet.ServletConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.xml.ws.Endpoint;

import com.garfield.webservice.HelloWebservice;

/** 
* 发布Java6 WebService的Servlet， 
* 
* @author leizhimin 2009-11-16 13:52:49 
*/ 
public class WSServlet extends GenericServlet { 
        @Override 
        public void init(ServletConfig servletConfig) throws ServletException { 
                super.init(servletConfig); 
                System.out.println("准备启动WebService服务：http://localhost:8888:8888/java6ws/Java6WS"); 
                //发布一个WebService 
                Endpoint.publish("http://localhost:8888/java6ws/Java6WS", new HelloWebservice()); 
                System.out.println("已成功启动WebService服务：http://localhost:8888:8888/java6ws/Java6WS"); 

        } 

        public void service(ServletRequest servletRequest, ServletResponse servletResponse) throws ServletException, IOException { 
                System.out.println("此Servlet不处理任何业务逻辑，仅仅yonglai发布一个Web服务：http://localhost:8888:8888/java6ws/Java6WS"); 
        } 
}

4.编辑web.xml:

<!DOCTYPE web-app PUBLIC
  ‘-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN‘
  ‘http://java.sun.com/dtd/web-app_2_3.dtd‘>
<web-app>
   
  <servlet> 
           <servlet-name>WSServlet</servlet-name> 
           <servlet-class>com.garfield.servlet.WSServlet</servlet-class> 
           <load-on-startup>1</load-on-startup> 
   </servlet> 
   <servlet-mapping> 
           <servlet-name>WSServlet</servlet-name> 
           <url-pattern>/servlet/WSServlet</url-pattern> 
   </servlet-mapping> 

</web-app>
