Linux（Ubuntu平台）JSP通过JDBC连接MySQL数据库，与Windows平台类似，步骤如下：

下载 jdbc： mysql-connector-java-5.1.18.tar.gz

解压 jdbc： tar -zxvf mysql-connector-java-5.1.18.tar.gz

配置 jdbc：cp mysql-connector-java-5.1.18-bin.jar /usr/local/jdk1.6.0_22/jre/lib/ext/

JSP示例：

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<%@ page language="java" import="java.sql.*"%>
<%@ page language="java" import="java.io.*" %>

<html>
<head>
<title>Read from mySQL Database</title>
</head>

<body>

<p align="center"><b>Following records are selected from table "gametop800"</b><br></p>


<center>
<table border="1" borderColor="#ffe9bf" cellPadding="0" cellSpacing="0" width="60%" >
	<tbody>
