Afficher deux servlets dans une meme page

**GhilesB206** · 18/06/2014, 11h22

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

Search.java

Code :

Bonjour,

Alors pourquoi tu n'as pas de jsp et pourquoi utilises tu 2 servlets?
la sortie standard 'out' va être écrasée à chaque fois que l'une des deux servlets est appelées. Tu devrais plutôt utiliser une seule servlet et selon tel ou tel paramètre effectuer ta requete...

Je pense que tu devrais re-penser un peu ton appli et repartir sur de bonne base (y a plein de petit tuto sur le net) car ton code va vite devenir illisible.

Bon courage ++.

Oui j'ai finalement tout mis dans une même servlet ResultSearch.
J'arrive a afficher le formulaire et la reponse en appelant la methode doGet() au debut de ma methode doPost() .
Cependant, en procedant de cette façon , mon formulaire se recharge deux fois ce qui prend un peu de temps mais pas tres beau a voir.
Aurais tu une solution?
Merci encore.

resultSearch.java:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

En fait je voudrais arriver à appeler ma methode doPost(requête,reponse) juste lorsque l'utilisateur clique sur le boutton search;
Par là , je voudrais afficher le resultat de ma recherche juste en bas du formulaire ..
J'ai pensé a créer une fonction JS qui fera appel à ma méthode Java (doPOst()) en rajoutant un "onClick="functionJS()" mais je n'ai pas réussi.
Un peu d'aide svp..
