jsp:include引用怎么弄啊

先把这个文件给分成两部分 一部分是数据库连接的 一部分是登陆的 但是不会用include 希望帮我分下
<%@ page contentType="text/html; charset=gb2312" %>

<%@ page language="java" %>
<%@ page import="com.mysql.jdbc.Driver" %>

<%@ page import="java.sql.*" %>
<%@ page import="java.io.*" %>
<%@ page import="java.util.*" %>
<jsp:include page="/include.jsp" flush="true"> </jsp:include>
<%
String driverName="com.mysql.jdbc.Driver";
String userName="root";
String userPasswd="123456";
String dbName="hoot";
String tableName="userinfo";
String encoding="characterEncoding=gb2312&useUnicode=true";
String url="jdbc:mysql://localhost/"+dbName+"?"+encoding+"&user="+userName+
"&password" +  "="+userPasswd;

Class.forName("com.mysql.jdbc.Driver").newInstance();

Connection connection=DriverManager.getConnection(url);
Statement statement = connection.createStatement();
//这一句必须要 不然还是登陆错误
request.setCharacterEncoding("gb2312");
        String Username=request.getParameter("Username");
