hi friend,

You can store the value in a Collection and you may access it on the JSP page. ResultSet is tied with the Connection so you can't access it without Connection. To pass the value to the JSP page you may use Request setAttribute method and at the JSP page can retrieve this value using Request getAttribute. Consider the following code may this will be helpful for you.


package net.roseindia;

import java.io.IOException;

import javax.servlet.RequestDispatcher;
import javax.servlet.ServletConfig;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import java.sql.*;
import java.util.ArrayList;
import java.util.List;

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

    public void init(ServletConfig config) throws ServletException{

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

        String driverName = "com.mysql.jdbc.Driver";
        String url = "jdbc:mysql://localhost:3306/record";
        String user = "root";
        String psw = "root";    
        Connection con = null;      
        PreparedStatement ps = null;
        ResultSet rs = null;

        List<String> list = new ArrayList<String>();

        String sql = "select * from country";

            con = DriverManager.getConnection(url, user, psw);
            ps = con.prepareStatement(sql);
            rs = ps.executeQuery();         
            request.setAttribute("list", list);         
            ServletContext context = getServletContext();
            RequestDispatcher rd = context.getRequestDispatcher("/rs.jsp");
            rd.forward(request, response);
        catch(Exception sqle)
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

        doGet(request, response);
