Je suis le tutoriel netbean, mais sans succès

Daromaster,

j'imagine que par voir si le componant s'appelle..., tu fais allusion au "id" du componant. j'ai encore verifié, dans la boite des propriétés, c'est bien -- "id = helloText" pour le static text et "id=nameField" pour le text Field.

Mais ce qui m'etonne est que netbean ne reconnaisse même pas les methodes comme .getText() et setText(); en plus, ce qui m'inquiete c'est que j'ai imprimé le tutoriel et je coche à chaque fois que j'ai accomplit une étape.

Merci encore pour ton aide. Voici, je te copie mon code, en esperant que je me suis trompé quelques part.

je commence par le code java, ensuite je mettrai aussi le code JSP

Je viens d'ecrire aux gens de Netbean sur le site, en esperant qu'il seront en mesure de (nous) aider. Et, j'ai comme l'impression qu'il n'y a pas que nous deux. Et cela à avoir avec (comme tu le dis) aux importations de packages.

Attendons-voir, si quelqu'un ou peut-être les gens de netbean vont se manifester

Pour lier un composant graphique (page JSP) à un objet Java (BackingBean Java), tu fais simplement un clic droit sur ton composant puis "Add Binding Attribute".

Ca créé un objet java avec un getter et un setter qui a exactement le même nom que l'id de ton composant graphique et maintenant tu peux agir sur ton composant graphique dans ton code java.

En général tu met les interactions dans la méthode prerender() mais je ne suis pas encore expert ^^

C'est tout ballot à faire mais j'avoue que c'est le petit truc qui n'est indiqué nulle part en clair dans la doc.
J'utilise NetBeans 6.1

Sinon tu peux le faire toi même en déclarant l'objet, le getter et le setter dans le code.
