en suivant je conpris que l'erreur venait surrement de cette ligne de mon code:
JasperDesign fichier = JRXmlLoader.load(file);
pourtant j'ai cru entendre que les java.lang.NoClassDefFoundError n'etatit pas une erreur de code et je voudrais aussi comprendre pourquoi mon
pilote n'est pas vues.
notons que file est le chemin vers mon fichier etat
String file="ressources/report2.jasper";
alors que faire? toutes aides,conseils,ou assistances seront les bien venus.
