Abrufen von Daten aus der servlet und der Druck in jsp

Ich Brauche Hilfe bei Vorgehensweise zum Drucken Ergebnismenge, Die ich Bin Immer Vom Servlet in Jsp
Hier Ist Der Servlet-Code:

import java.io.IOException;
import java.io.PrintWriter;
import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.Statement;

import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

public class EditRecord extends HttpServlet {
private static final long serialVersionUID = 1L;

Connection con;
Statement stmt;
ResultSet rs;
DBConnection dbconn;
String sql;
HttpSession session;

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws       ServletException, IOException {
    doPerform(request, response);
}

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    doPerform(request, response);
} 

private void doPerform(HttpServletRequest request,HttpServletResponse response) 
{

    try {
        PrintWriter out = response.getWriter();
        System.out.println("This is EditRecord Servlet");
        session= request.getSession();
        String id =(String) session.getAttribute("id");
        System.out.println(id);
        dbconn = new DBConnection();
        con= dbconn.getConnection();
        System.out.println(con);
        sql ="select * from STUDENT_CRUD where id='"+id+"' ";
        System.out.println(sql);
        stmt = con.createStatement();
        rs = stmt.executeQuery(sql);
        System.out.println("Resultset From EditRecord Servlet  ="+rs);
        if(rs.next())
        {
            System.out.println(rs.getString(1));
            System.out.println(rs.getString(2));
            System.out.println(rs.getString(3));
            System.out.println(rs.getString(4));
            System.out.println(rs.getString(5));
        }


    } 
    catch (Exception e) 
    {

        e.printStackTrace();
    }
    finally
    {

        try 
        {
            session.setAttribute("resultset", rs);
            RequestDispatcher rd= request.getRequestDispatcher("editrecord.jsp");
            rd.forward(request, response);
            //response.sendRedirect("editrecord.jsp");
        } 
        catch (Exception e) 
        {
            System.out.println("This is finally block editrecord.jsp");
            e.printStackTrace();
        }
    }

}

Dann Die Jsp-Datei, die ich Schreibe, ist wie:

<%@page import="java.sql.ResultSet"%>
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>

<form name="editrecord">

    <% ResultSet rs =(ResultSet)session.getAttribute("resultset"); 
      out.println("this is getAttribute of resultset"+rs);

    %>
     <TABLE BORDER="1">
        <TR>
            <TH>ID</TH>
            <TH>FIRSTNAME</TH>
            <TH>LASTNAME</TH>
            <TH>SUBJECT</TH>
            <TH>YEARS</TH>
        </TR>
        <% while(rs.next()){ %>
        <tr>
 <!--               <td>ID</td> -->
            <td> <input type="text" name="id" value="<%=rs.getString(1) %>"></td>
        </tr>
        <tr>
<!--                <td>FirstName</td> -->
            <td><input type="text" name="firstname" value="<%=rs.getString(2) %>"></td>
        </tr>
        <tr>
<!--                <td>LastName</td> -->
            <td><input type="text" name="lastname" value="<%=rs.getString(3) %>"></td>
        </tr>
        <tr>
<!--                <td>Subject</td> -->
            <td><input type="text" name="subject" value="<%=rs.getString(4) %>"></td>
        </tr>
        <tr>
<!--                <td>years</td> -->
            <td><input type="text" name="years" value="<%=rs.getString(5) %>"></td>

        </tr>           
        <% } %>
    </TABLE>    



 </form>    

Dem Ergebnis bin ich immer :

enter code here

dies ist getAttribute von resultsetoracle.jdbc.driver.OracleResultSetImpl@5e79fc
ID FIRSTNAME LASTNAME SUBJECT JAHREN

Den ResultSetData ich bin Immer innerhalb EditServet aber nicht in editrecord.jsp-Warum?
pls help..........
