Answer 1

i résolu ce problème en utilisant javascript window.location au lieu d'envoyer Rediriger

window.location = "home.jsp";

Answer 2

Il semble que vous essayez toujours d'écrire quelque chose à la réponse. Pouvez-vous ajouter une déclaration de retour après la redirection.

response.sendRedirect((“home.jsp”)); 
return;
