Afficher deux servlets dans une meme page
Bonjour a tous ,
Je souhaiterai afficher le résultat de mon formulaire contenu dans une servlet dans une même page que le résultat (Formulaire , puis juste en bas le résultat de ma requête.
J'ai essayé request.getDispatcher(..) mais je n'ai pas réussi.
J'ai deux servlet , l'une affichant le formulaire a remplir . J'ai utilisé des select pour que l'utilisateur puisse choisir parmi une liste choisis dans la bdd (search).
ResultSearch affiche le résultat de la requête .
Je vous joins le code de mon projet pour y voir plus claire
