Merci
Hello,

Ton import du Logger est pas bon.

Remplace :

import com.sun.istack.internal.logging.Logger;


par :
import java.util.logging.Logger;

De préférence j'utilise le Logger de slf4j.
http://www.slf4j.org/apidocs/org/slf4j/Logger.html


Si c'est corrigé, pense à mettre résolu et noter la réponse.
