page servlet
import java.io.*;
import java.net.*;
import java.sql.*;
import javax.servlet.*;
import javax.servlet.http.*;
/**

* @version
*/
public class liste23 extends HttpServlet {
public Connection con;
private PrintWriter out;
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
}
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
processRequest(request, response);
}
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
try
{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver").newInstance();
String url="jdbc:odbc:test5";
con=DriverManager.getConnection(url,"","");
Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery("SELECT * FROM etud");
HttpSession session = request.getSession(true);
session.setAttribute("resultset", rs);
response.sendRedirect("liste2.jsp");}
catch(Exception e)
{
System.out.println(e);
}
}
public String getServletInfo() {
return "Short description";
}
// </editor-fold>
}
et page jsp

<%@page pageEncoding="UTF-8"%>
<%@ page import="java.util.*" %>
<%@ page import="java.text.*" %>
