Que veut dire cette erreur (au runtime) ?

Bonjour,
Le programme compile mais quand je le lance il mecrit cela:

Code:

---

1 2 3 4 5 6 7

run: Exception in thread "main" java.lang.NullPointerException: Canvas3D: null GraphicsConfiguration at javax.media.j3d.Canvas3D.checkForValidGraphicsConfig(Canvas3D.java:954) at javax.media.j3d.Canvas3D.<init>(Canvas3D.java:997) at courseworkjava3d.Simple3D.<init>(Simple3D.java:42) at courseworkjava3d.Simple3D.main(Simple3D.java:982)

Je suis a 100% certain que cela marchait sans que je touche au code, et maintenant cela me faire cela, sous netbeans 5.5

Je le sais car jai fait un backup qui fonctionnait et quand jai verifier avec le backup, cela me fait ca aussi...

Je precise je "cleane" le project avant de compiler! et je ferme les "runtimes process" sous netbeans 5.5


Merci!
:)

que t'as pas instancié un objet

mais avec le code ça serait plus facile

erm....Merci de ton aide!

Je crains que vous allez pleurer pour le code... :oops:

encore une fois je suis casi 100% certain ca marchait!
et je nai rien changer de ce cote la qui fairait cet erreur!
Elle apparait aleatoirement des fois et maintenant tout le temps!

Et mon backup aurait du fonctionner aussi!

Je me demande si jai changer un nom par megarde, ou si c genre quelquechose qui se change tout seul dans mon code quand je compile!

Je crois qu'il deraille la il me dit "run:
Error: could not open `C:\Program Files\Java\jre1.6.0_05\lib\i386\jvm.cfg'
"
alors que jai rien toucher moi!!!

:?

Envoyé par LeXo

que t'as pas instancié un objet

mais avec le code ça serait plus facile

wouhou! La ca remarche alors quencore uen fois je n'ai rien toucher au code!

Jai juste eteind le pc la nuit...

Je laisse le sujet ouvert au cas ou parceque des fois jai quand meme cet erreur...
:?

Merci en tout cas de l'aide :D

Je vais marquer comme "resolu"...

J'avais eu ce probleme un petit nombre de fois, puis tout le temps.
Mais quand jai eteind puis redemarrer le pc, il a disparu, je pense donc qu'il s'agissait d'un bug...
