Redirect, Forward aucun ne marche?!
Salut a tous,
J'ai developpe 2 servlets et 1 JSP qui communique entre elles.
La 1ere servlet (AGSenderServlet) appelle la 2eme servlet (AGReceiverServlet) pour lui envoyer un fichier.
Ensuite, une fois le fichier recu, la 2eme servlet appelle la page JSP.
Tout marche bien sauf le dernier appel pour la JSP. Rien ne se passe en fait. Pas d'erreur ou d'exception. Le code de la JSP n'est meme pas parcouru.
Voici mes 2 servlets:

J'ai poste mon probleme sur le forum Java mais y a qu'une personne qui m'a repondu et je comprend pas vraiment ce qu'il a voulu m'explique. Apparemment ca viendrait de la reponse envoyee par response.sendRedirect(redirectURL); de ma 2eme servlet qui n'est bien interprete par ma 1ere servlet :roll:
J'ai essaye d'utiliser la fonction forward du dispatcher mais ca me donne le meme resultat.
