Incompréhension dans l'enchainement des pages
Bonjour,
Je m'attendais à ce que mon code suive le chemin que j'avais déterminé au préalable, c'est à dire firstJsp.jsp => bouton submit => modify.jsp. Or il va directement à display.jsp et j'avoue ne pas comprendre pourquoi.
Ci joint les deux jsp & les servlet associé. Je ne pense pas que le code modele soit nécessaire, je le rajouterai si besoin. Merci d'avance.

// HttpSession session = request.getSession();
InterfaceBDD toto = (InterfaceBDD) session.getAttribute("Bdd");
String[] str;
out.println("<table><caption>Liste d'utilisateurs</caption><thead>"

int a = 0;
while ((str = toto.display(a)) != null) {
out.println("<tr><td><input type=\"radio\" name=\"validation\" value=\""
