開發環境：jdk1.6+myeclipse6.5+mysql5.0+tomcat6.0.14

1.第一步：在apache-tomcat-6.0.14/conf/context.xml中添加：用於配置JNDI的名字
其中的代碼如下：
   <Resource name="jdbc/mysql"
    type="javax.sql.DataSource"
    password="alen"
    driverClassName="com.mysql.jdbc.Driver"
    maxIdle="40"
    maxWait="5000"
    username="root"
    url="jdbc:mysql://localhost:3306/spacedebris"
    maxActive="40"/>

加到<Context> </Context>之間

2.第二步：在項目的web.xml加入代碼：
<resource-ref>
<description>mysqlDB</description>
<res-ref-name>jdbc/mysql</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>

放在<web-app version="2.4" > </web-app>之間

3.用jsp代碼測試：
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ page import="java.sql.*,javax.sql.*,javax.naming.*"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
    <base href="<%=basePath%>">

    <title>My JSP 'MySqlDSTest.jsp' starting page</title>

<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">

</head>

<body> 
    <%
    DataSource ds=null;
    try{

      InitialContext ctx=new InitialContext();
      ds=(DataSource)ctx.lookup("java:comp/env/jdbc/mysql");
      Connection conn=ds.getConnection();
      conn.close();
      out.println("JNDI串連MYSQL測試成功！");
    }catch(Exception ex){
      out.println(ex.getMessage());
    }
    %>
</body>
</html>

最後效果如下：

JNDI串連MYSQL測試成功！
