[1]写index.jsp文件

<%@ page contentType="text/html;charset=gb2312"%>

  <body>

    <script type="text/javascript">

    var req;

     function validate() {

         var idField = document.getElementById("userid");

         var url = "servlet/ValidateServlet?id=" + escape(idField.value);

         if (window.XMLHttpRequest) {

             alert("0");

             req = new XMLHttpRequest();

         }else if (window.ActiveXObject) {

             alert("1");

             req = new ActiveXObject("Microsoft.XMLHTTP");

         }

        if(req){

            req.open("GET", url, true);

             req.onreadystatechange = callback;

            req.send(null);       

         }

    }

function callback() {

    if (req.readyState == 4) {

        if (req.status == 200) {

                 parseMessage();

                 // update the HTML DOM based on whether or not message is valid

        }else{

            alert ("Not able to retrieve description" + req.statusText);

        }      

    }

}

function parseMessage() {

    setMessage(message.firstChild.data,name.firstChild.data);

}

 function setMessage(message,name) {

     var userMessageElement = document.getElementById("userIdMessage");

     userMessageElement.innerHTML = "<font color=\"red\">" + message + " you "+name+"</font>";

 }

</script>

<div id="userIdMessage"></div>

    <input type="text"

            size="20"

              id="userid"

[2] 写servlet/ValidateServlet.java类

/*

 * 创建日期 2005-8-3

 *

 * TODO 要更改此生成的文件的模板，请转至

 * 窗口 － 首选项 － Java － 代码样式 － 代码模板

 */

package com;//com包需要自己创建.

 

import java.io.IOException;

import java.io.PrintWriter;

import java.util.HashMap;

 

import javax.servlet.ServletConfig;

import javax.servlet.ServletContext;

import javax.servlet.ServletException;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

 

/**

 * @author Administrator

 *

 * TODO 要更改此生成的类型注释的模板，请转至

 * 窗口 － 首选项 － Java － 代码样式 － 代码模板

 */

public class ValidateServlet extends HttpServlet {

 

    /**

     * Constructor of the object.

     */

  

    private ServletContext context;

    private HashMap users = new HashMap();

 

    public ValidateServlet() {

        super();

    }

 

    /**

     * Destruction of the servlet. <br>

     */

    public void destroy() {

        super.destroy(); // Just puts "destroy" string in log

        // Put your code here

    }

 

    /**

     *

     * This method is called when a form has its tag value method equals to get.

     *

     * @param request the request send by the client to the server

     * @param response the response send by the server to the client

     * @throws ServletException if an error occurred

     * @throws IOException if an error occurred

     */

    public void doGet(HttpServletRequest request, HttpServletResponse response)

            throws ServletException, IOException {

        response.setContentType("text/xml");

        response.setHeader("Cache-Control", "no-cache");

      

        String targetId = request.getParameter("id");

        System.out.println(targetId.trim());

 

        if ((targetId != null) && users.containsKey(targetId.trim())) {

 

                          response.getWriter().write("<info><message>welcome</message><name>sdl</name></info>");

        } else {

 

                  response.getWriter().write("<info><message>kill</message><name>bush</name></info>");

                System.out.print("invalid");

            }

 

 

    }

    /**

     */

    public void init(ServletConfig config) throws ServletException {

        this.context = config.getServletContext();

        users.put("greg","account data");

        users.put("duke","account data");

 

    }

 

}

[3]写web.xml文件

<?xml version="1.0" encoding="UTF-8"?>

<web-app version="2.4"

    xmlns="http://java.sun.com/xml/ns/j2ee"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee

    http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

  <servlet>

    <description>This is the description of my J2EE component</description>

    <display-name>This is the display name of my J2EE component</display-name>

    <servlet-name>ValidateServlet</servlet-name>

    <servlet-class>com.ValidateServlet</servlet-class>

  </servlet>

 

  <servlet-mapping>

    <servlet-name>ValidateServlet</servlet-name>

    <url-pattern>/servlet/ValidateServlet</url-pattern>

  </servlet-mapping>

</web-app>

[4]说明：
你可以在IE或FireFox里测试，在文本输入框里输入，当按键抬起，会在层中显示”kill you bush”。其中index.htm中的styles.css只是美化页面，没有列出来源代码。如果在servlet向客户端输出中文，需要编码转换。

]]>Axis开发之Stubs方式 http://www.blogjava.net/codefans/articles/32371.html春雷的博客春雷的博客Sat, 25 Feb 2006 03:09:00 GMThttp://www.blogjava.net/codefans/articles/32371.htmlhttp://www.blogjava.net/codefans/comments/32371.htmlhttp://www.blogjava.net/codefans/articles/32371.html#Feedback0http://www.blogjava.net/codefans/comments/commentRss/32371.htmlhttp://www.blogjava.net/codefans/services/trackbacks/32371.html1、建立代理接口文件
public interface ISendSms extends java.rmi.Remote {
    public String getUser(String id,String type);
}

转到在目录..\WebRoot\WEB-INF\classes下:

2、生成client stub文件, 生成SendSms.wsdl文件
java -Djava.ext.dirs=../lib org.apache.axis.wsdl.Java2WSDL -oSendSms.wsdl -lhttp://localhost:8080/websms/services/SendSms -n"urn:SendSms" -p"sample.webservice" "urn:SendSms" sample.webservice.ISendSms

生成的SendSms.wsdl文件中，参数名称默认为in1,in2等，需要改成相应的名称。

3、生成client stub
java -Djava.ext.dirs=../lib org.apache.axis.wsdl.WSDL2Java -o . -d Session -s -S true -Nurn:SendSms sample.webservice SendSms.wsdl

生成的文件列表如下:
deploy.wsdd
undeploy.wsdd
ISendSms.java
ISendSmsService.java
ISendSmsServiceLocator.java
SendSmsSoapBindingImpl.java
SendSmsSoapBindingSkeleton.java
SendSmsSoapBindingStub.java

4、布署服务,在WEB-INF目录下生成server-config.wsdd文件, 随Tomcat启动自动加载里面定义的服务
转到目录..\WebRoot\WEB-INF\classes\sample\webservice下
java -cp %AXISCLASSPATH% org.apache.axis.client.AdminClient -lhttp://localhost:8080/websms/services/AdminService deploy.wsdd

在Axis里书写deploy.wsdd并利用org.apache.axis.client.AdminClient发布，其主要工作就是把<service>标签中的内容添加在server-config.wsdd里，所以一般直接编辑server-config.wsdd文件会更方便一些。不过当你还没有server-config.wsdd文件时，使用deploy.wsdd的方法会更方便些，因为AdminClient会帮你生成一些额外的xml元素（<handler>等等），而这些元素是必要的。

5、项目中加入Axis所需的包, web.xml加入相关定义
  <display-name>Apache-Axis</display-name>
  <servlet>
    <display-name>Apache-Axis Servlet</display-name>
    <servlet-name>AxisServlet</servlet-name>
    <servlet-class>
        org.apache.axis.transport.http.AxisServlet
    </servlet-class>
  </servlet>
  <servlet>
    <display-name>Axis Admin Servlet</display-name>
    <servlet-name>AdminServlet</servlet-name>
    <servlet-class>
        org.apache.axis.transport.http.AdminServlet
    </servlet-class>
    <load-on-startup>100</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>AxisServlet</servlet-name>
    <url-pattern>/services/*</url-pattern>
  </servlet-mapping>

通过http://localhost:8080/websms/services/SendSms?wsdl来查看WSDL描述了

6、测试代码
public static void main(String[] args) {
  try{
  /*ISendSmsService service = new ISendSmsServiceLocator();
   ISendSms sender = service.getSendSms();
   String result = sender.send("cid","cname");
   System.out.println("call result:"+result);*/
   String tvServiceURL = "http://localhost:8080/websms/services/SendSms"; //web service 地址
   java.net.URL endpointURL = new java.net.URL(tvServiceURL);
   String result = "ok";
   result = new SendSmsSoapBindingStub(endpointURL,null).send("id","cname");
   System.out.println("call result:"+result);
  }
  catch(Exception ex){
   ex.printStackTrace();
  }
 }

我们还可以通过IE浏览器直接调用服务，方法是在服务URL后加“method=xxx”，其中xxx是要调用的方法名称。例如可以通过http://localhost:8080/websms/services/SendSms?method=send&userId=uid&...调用方法。
====================================================================================
另外,  也可能过新建一个deploy.wsdd文件，通过这个文件直接布署我们的服务
java -Djava.ext.dirs=lib org.apache.axis.client.AdminClient -lhttp://localhost:8080/websms/services/SendSms deploy.wsdd
// 它会在WEB-INF目录生成server-config.wsdd文件, 若此文件已存在, 它会在文件加入当前服务的注册。

生成wsdl文件
java -Djava.ext.dirs=../lib org.apache.axis.wsdl.Java2WSDL -oSendSms.wsdl -lhttp://localhost:8080/websms/services/SendSms -nsendsms sample.webservice.SendSms

生成客户端文件
java -Djava.ext.dirs=../lib org.apache.axis.wsdl.WSDL2Java SendSms.wsdl -p client
