自己分页，下一篇会介绍使用diasplaytag组件。
使用mysql5, 有个数据表user,字段有id, username, password。
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
<%@ page import="java.sql.*"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

String driver = "com.mysql.jdbc.Driver";
String username = "root";
String password = "leng";
String url = "jdbc:mysql://localhost/test";
Connection conn = null;
Statement stmt = null;
ResultSet rs = null;
Class.forName(driver);
conn = DriverManager.getConnection(url, username, password);
stmt = conn.createStatement();
String sql = "select * from user order by id asc";
rs = stmt.executeQuery(sql);
%>
<%
int countRecord = 0; //总记录数
int pageSize = 4; // 每页记录数
int countPage = 0 ; // 总页数
int dipage = 1; // 当前页码，默认从1开始
String pages = request.getParameter("page");
if(pages == null ){
pages = "1";
}
dipage = Integer.parseInt(pages);
rs.last();
countRecord = rs.getRow();
if(countRecord % pageSize == 0){
countPage = countRecord / pageSize;
} else {
countPage = countRecord / pageSize + 1;
}
if((dipage-1)*pageSize == 0){
// 第一页
rs.beforeFirst();
} else {
rs.absolute((dipage-1)*pageSize);
}
%>
<body>
<center>
