"naissance_eleve" should probably better be of type DATE in your database. If you cannot change that, I assume "naissance_eleve" is always in ISO, i.e. like '2017-12-3' etc.? Then you use java.text.SimpleDateFormat for conversion. — Heiko Jakubzik, Dec 03 '17 at 13:01
@HeikoJakubzik Actually, standard [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601) format pads with leading zeros, so make that `2017-12-03`. — Basil Bourque, Dec 04 '17 at 05:52

I'm not exactly sure how to translate this into JSP. I do remember that JSPs can contain Java. This sample of Java code creates a SimpleDateFormat of two locales, US and France, parses and formats the date and outputs the result.

public static void main(String[] args)
{

  Date d = new Date();
  SimpleDateFormat sdf_us = new SimpleDateFormat("yyyy-MMMM-dd",Locale.US);
  SimpleDateFormat sdf_fr = new SimpleDateFormat("yyyy-MMMM-dd",Locale.FRANCE);
  String output = sdf_us.format(d);
  System.out.println(output);
  System.out.println(d);
  try
  {
    d = sdf_us.parse(output);
    String output_fr = sdf_fr.format(d);
    d = sdf_fr.parse(output_fr);
    System.out.println(output_fr);
    System.out.println(d);
  }
  catch (ParseException e)
  {
    // TODO Auto-generated catch block
    e.printStackTrace();
  }
}

The output is

2017-December-03

Sun Dec 03 07:15:57 CST 2017

2017-décembre-03

Sun Dec 03 00:00:00 CST 2017

No time appears in the last one because it was removed when the format didn't cover it.

My guess would be

    <tr><td>Date Naissance</td><td><input type="date" name="naissance_eleve" value="
<%      
  SimpleDateFormat sdf_fr = new SimpleDateFormat("yyyy-MMMM-dd",Locale.FRANCE);
  String output = sdf_fr.format(naissance_eleve);
  out.print(output);

%>"/></td></tr>

This Answer is ill-advised, using troublesome old legacy date-time classes supplanted by the java.time classes. — Basil Bourque, Dec 04 '17 at 05:50
