Applet Java

Cyber Liz, le mardi 8 juin 2004 à 16:22:03

Bonjour,

J'ai un problème en java : j'ai quatre fichiers (.java) dans le même package. Chaque fichier contient une classe. Lorsque j'essais de créer un objet d'une classe venant d'un des autres fichiers, j'ai l'erreur:
"cannot resolve symbol
symbol : class progress
location: class javaupload.uploadWindow
m_bar = new progress();
"

Je ne peux pas créer d'objet progress qui se trouve dans un autre fichier du même package.

Svp aidez-moi!
Merci!

Vive le Québec libre! Et oui, je suis québécoise...

Salut
as tu bien fait ta declaration au debut
progress m_bar;
dans ton code
ensuite as tu aussi mis en debut de chaque classe
package chemin.nom_package;

et oui vive le Québec libre qu'ont en finissent une bonne fois pour toute avec tous ces chanteurs quebequois ;-)( je lol)

Lol! Si tout le monde pensait comme toi, ça ferait longtemps que le Québec serait indépendant!

Pour revenir au problème, j'ai bien fait ce que tu as dit. J'ai réussi à faire les .class (enfin) avec la commande javac javaupload/*.java. Je ne réussi pas à les faire séparément mais si je fais cette commande, ça me créer les fichiers. J'ai cependant un autre problème:

Je veux afficher cet applet dans ma page web. La page est située dans le même dossier que les .class. Mais j'obtiens cette erreur dans la console java:

java.lang.NoClassDefFoundError: upload (wrong name: javaupload/upload)

Le code de ma page web est :

<HTML>
<HEAD>
<TITLE>Upload</TITLE>
</HEAD>
<BODY>
<APPLET Code="upload.class"
Width=300
Height=50>
Votre navigateur ne supporte pas les applets.
</APPLET>
</BODY>
</HTML>

Est-ce que je dois mettre le nom de tous mes fichiers .class? Si oui, où dois-je le faire? Pourquoi ça donne cette erreur?

J'ai essayé javac maclasse.java mais pas java maclasse.java.

Je suis capable de créer seulement un des fichiers avec ca, les trois autres ca ne marche pas. La seule façon c'est de les faire tous à la fois. Upload fait appel à une des autres classes.

T'as une idée de pouquoi ca marche pas?

oups pardon c est bien javac lol j ai rippé...
tu as essayé en utilisant un cmpilateur style jcreator..pour compiler le tout dans le package proprement il te donnera peu etre plus de detail...tu devrai trouver des version shareware sur le net...

bon courage..

J'ai essayé avec JBuilder mais ça ne fonctionne pas. Il dit qu'il ne trouve pas le main... c'est sûr c'est un applet! Alors je ne peux pas faire mes fichiers .class avec JBuilder. C'est pour ça que je les ai fait manuellement avec le terminal.

Je me suis fait un autre applet plus simple pour tester, mais ça ne marche pas plus.

peux tu essayer ca:

import java.applet.*;
import java.awt.*;

public class HelloWorldApplet extends Applet implements Runnable {
private boolean mustStop;
private int red=0, green=0, blue=0;

// Démarrage de l'applet
public void start() {
this.mustStop = false;
(new Thread(this)).start();

}

// Arrêt de l'applet
public void stop() {
this.mustStop = true;
}

// Un nouveau thread pour la réactualisation de l'applet
public void run() {
while(true) {
this.paint(this.getGraphics());
try { Thread.sleep(5); } catch(Exception e) {}
if (this.mustStop == true) return;
}
}

// Fait varier aléatoirement une composante de couleur
public int randomChange(int composante) {
if (Math.random() < 0.5) {
if (composante>0) composante--;
} else {
if (composante<255) composante++;
}
return composante;
}

// Dessine de contenu de l'applet
public void paint(Graphics gc) {
red = this.randomChange(red);
green = this.randomChange(green);
blue = this.randomChange(blue);

gc.setColor(new Color(red, green, blue));
gc.setFont(new Font(gc.getFont().getName(), Font.BOLD, 26));
gc.drawString("Administration",75,35);
}
}

pour voir si cela vient de ton compilo ou de ton code...

J'ai déjà fait un applet HelloWord pour tester (c'est un classique). Ça fonctionne, mais seulement quand j'ai juste un fichier. Dès que je mets le mot package pour essayer de faire le lien entre les classes, ça plante. Le seul moyen d'avoir plusieurs classes, c'est de mettre toutes mes classes dans le même fichier, d'en mettre une publique et de mettre les autres classes à l'intérieur de cette classe. Mais ce n'est pas super comme méthode... Il doit bien y avoir un moyen d'utiliser plusieurs fichiers.

Bonjour,
Je débute en java et j'aurai besoin, en urgence, d'un applet permettant
d'uploader un dossier (tous les fichiers recursivement) sur le serveur dans
un dossier dont le nom est demandé.
Je vous remercie d'avance pour toute information susceptible de m'aider,
tutos, snippet, projets open source...

Bonjour,
J'aimerai bien que quelqu'un m'explique à quoi sert le thread dans l'exemple.
J'essaie aussi de faire une applet d'upload et je m'inspire de celui-ci.

Le thread ne fait qu'instancier un objet où est l'intérêt du thread.
