jsp+servlet+javaBean怎样实现分页

我写了类协作访问数据库，但是不知道如何分页，现在将问题描述如下：
我想要问的是如何在该servlet中建立List类将查询结果转发到jsp，并且使用tld自定义标记库和分页，那位朋友有类似的例子的发一份给我参考下，并希望有注释。我的联系方式q:254475842 邮箱:[e-mail]

//SearchDept.java

查询的servlet类：这个地方不会写List类和分页，需要问各位的在此：

package com.servlet;

import java.io.IOException;
import java.io.PrintWriter;
import java.sql.*;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.javaBean.DeptTest;

 public class SearchDept extends javax.servlet.http.HttpServlet implements javax.servlet.Servlet
 {
   static final long serialVersionUID = 1L;
   private static String DDno;
   static ResultSet rs=null;
   static String DDname=null;
    public SearchDept()
    {
        super();
    }      
   
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
    {

     
        doPost(request,response);
       
    }     
   
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
    {
      response.setCharacterEncoding("GB2312");
      PrintWriter out=response.getWriter();
      String Dno=request.getParameter("Dno");
     
      DeptTest dt=new DeptTest();
     try
     {
         rs=dt.SearchDeptbyDno(Dno);
         if(rs.next())
         {
             DDno=rs.getString("Dno");
             DDname=rs.getString("Dname");
             if(Dno.equals(DDno))
                {
                out.println(DDno);
                out.println(DDname);
                }
         }
         else
         {
             response.sendRedirect("SearchDept.html");
         }
         
     }
     catch (SQLException e)
     {
       
        e.printStackTrace();
     }
   
     
    }
