Bonjour,

la cause de l'erreur est écrite dans ta sortie :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

Caused by: java.security.AccessControlException: access denied (java.io.FilePermission U0.txt read)

ce qui signifie que ton applet n'a pas la permission d'accès en lecture du fichier U0.txt.

Comment changer les autorisations dans ce cas??
merci d'avance
