Bonsoir,
j'ai eu une erreur en exécutant mon code, que j'arrive pas à la résoudre

est ce que je dois changer de version du Jena TDB que j'utilise?
NB: j'utilise jenatdb 0.8.10, j'ai aimé bien de travaille avec Jena TDB 0.9.0 mais lorsque j’exécute mon code il m'a affiche un warn que je dois initialiser le log4j
Merci pour toute intervention :)
