Du coup je ne peux plus compiler mes projets. De plus , il me dit que tout mes fichiers ou projets ne contiennent pas de fonction main a compiler...
Merci d'avance, je ne peux plus travailler

Le système GUI de Netbeans génére deux fichiers pour un Panel:
- .java : contient le source
- .form : contient les informations nécessaires à l'affichage de la form (Matisse).

Tu dois avoir une erreur dans "FileViewerPanel.form", dans répertoire de "FileViewerPanel.java".

Maintenant, si tu nous dis pas tout -le fichier a due se casser pour une bonne raison car rare- on pourra pas faire mieux !

Le probleme c'est que je ne connaissais pas la cause de cette erreur, elle est apparue subitement...
Mais mon service informatique a reussi a reparer ..
Merci d'avoir pris le temps de me repondre
