Impossibilité à remplir la BD

Bonjour;

Ayant créer un dictionnaire sous netbeans avec comme SGBD postgresql,normalement dès que je clique sur le bouton ok un message indique que j'ai insérer le mot.Or,je n'arrive pas à remplir la table dico de la base de données puisque mon message n’apparait pas.
Ma base de données est nommée Dictionary elle contient une table nommée dico qui contient les colonnes suivantes:id,word,meaning,french,sentence,synonym,type

Code:

Pourriez vous m'aider please

Cordialement.

Salut,

L'insertion de données est censée être faite par la méthode jbutton2ActionPerformed(), qui n'est appelée nulle part : comme tu ne nous a pas mis le code de initComponents(), dans lequel, à priori le bouton concerné devrait être créé et sur lequel l'écouteur d'évènement adéquat devrait être enregistré (qui devrait donc appeler la méthode jButton2ActionPerformed()), difficile d'en dire plus.

Re bonjour;

J'ai recopié mon code

Merci d'avance.

Ok, donc le code est bien appelé, normalement si tu appuies sur ton bouton : tu dois au moins avoir le message "a word is inserted" ? Si ce n'est pas le cas, je ne vois pas trop pourquoi... maintenant, peut-être que si tu ajoutais une trace des exceptions dans le(s) catch(s) vide(s), on pourrait voir qu'il y a une erreur, le cas échéant.

Ensuite, il manque juste un commit pour valider l'insertion dans la base (après l'invocation de executeUpdate(() dans jButton2ActionPerformed(ActionEvent)).

au fait je maitrise pas bien les exceptions mais je vais m'y appliquer et rajouter ce qui manque

Merci pour votre aide.:)

Les méthodes que tu utilises pour communiquer avec la base soulève du java.sql.SQLException, donc il suffit, pour commencer, d'écrire :

Code:

---

1 2 3 4 5

catch(SQLException sqle) {   sqle.printStackTrace();   }

---

avec l'import import java.sql.SQLException;Déjà, avec ça, tu verras dans la console, si tu as des erreurs ou pas.

Bonjour,

En exécutant cette méthode j'ai la ligne de code suivante qui est tracée en rouge:

Class.forName("org.postgresql.Driver");


donc y a t'il une autre option à explorer?

Il faut également que tu catch ClassNotFoundException comme ceci :

Code:

---

1 2 3 4 5

catch(ClassNotFoundException c) {   c.printStackTrace();   }

---

Mais si tu utilises un IDE (Eclipse ou Netbeans par exemple) en cliquant sur l'erreur, il devrait te proposer de le faire automatiquement. Cependant, regarde comment fonctionne le système d'exception en java c'est toujours utile.

J'ai tout essayé et ça marche toujours pas ,que faire?

Tu as au moins ajouté, comme indiqué par @Freeway57, le catch de l'exception de type ClassNotFoundException ?

Code:

---

1 2 3 4 5

try { Class.forName("org.postgresql.Driver"); } catch (ClassNotFoundException cnfe) { cnfe.printStackTrace(); }

---

Donc, maintenant que tu exécutes ton code, si tu as des erreurs lors de l'exécution, tu dois avoir des traces dans la console, avec toutes les informations utiles pour comprendre ce qui ne va pas.

le code permet de débugger .. ce qui est utile dans ton cas.
mais quand ça marche tu peux le supprimer: le ServiceLoader de JDBC va trouver automagiquement les drivers qui sont dans son CLASSPATH

j'ai suivi à la lettre ,mon code ne marche toujours pas,je n'ai pas de fenêtre out put pour vérifier ou se trouve l'erreur
