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-zxvfmysql-connector-java-5.1.18.tar.gz

配置jdbc：cpmysql-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>

Following records are selected from table "gametop800"

<center>
<table border="1" borderColor="#ffe9bf" cellPadding="0" cellSpacing="0" width="60%" >
	<tbody>
		<tr>
			<td bgColor="#008080" width="10%" height="28" align="center" valign="middle">
				top</td>
			<td bgColor="#008080" width="30%" height="28" align="center" valign="middle">
				id</td>
			<td bgColor="#008080" width="20%" height="28" align="center" valign="middle">
				name</td>
			<td bgColor="#008080" width="20%" height="28" align="center" valign="middle">
				country</td>
			<td bgColor="#008080" width="20%" height="28" align="center" valign="middle">
				dtime</td>
		</tr>
		<%
			String DRIVER = "com.mysql.jdbc.Driver";
			String url = "jdbc:mysql://localhost:3306/top800";

Connection con = null;
			ResultSet rst = null;
			Statement stmt = null;
			
			int i = 1;

try {
				Class.forName(DRIVER).newInstance();
				
				con = DriverManager.getConnection(url, "root", "");
				stmt = con.createStatement();
				rst = stmt.executeQuery("select top, id, name, country, dtime from gametop800 where top=1");
				while (rst.next()) {
					if (0 == i%2) {
		%>
		<tr>
			<td bgColor="#ffff98" width="10%" height="18" vAlign="middle" align="center"><%=rst.getInt(1)%>.</td>
			<td bgColor="#ffff98" width="30%" height="18" valign="middle"><%=rst.getString(2)%></td>
			<td bgColor="#ffff98" width="20%" height="18" valign="middle"><a href="<%=rst.getString(3)%>"><%=rst.getString(3)%></a></td>
			<td bgColor="#ffff98" width="20%" height="18" valign="middle"><%=rst.getString(4)%></td>
			<td bgColor="#ffff98" width="20%" height="18" valign="middle"><%=rst.getString(5)%></td>
		</tr>
		<% } else {
		%>
		<tr>
			<td bgColor="#ffcc68" width="10%" height="18" valign="middle" align="center"><%=rst.getInt(1)%>.</td>
			<td bgColor="#ffcc68" width="30%" height="18" valign="middle"><%=rst.getString(2)%></td>
			<td bgColor="#ffcc68" width="20%" height="18" valign="middle"><a href="<%=rst.getString(3)%>"><%=rst.getString(3)%></a></td>
			<td bgColor="#ffcc68" width="20%" height="18" valign="middle"><%=rst.getString(4)%></td>
			<td bgColor="#ffcc68" width="20%" height="18" valign="middle"><%=rst.getString(5)%></td>
		</tr>
		<% }
			i++;
				}
				rst.close();
				stmt.close();
				con.close();
			} catch (Exception e) {
				System.out.println(e.getMessage());
			}
