Qu'est-ce qui se passe ici? Qu'en est-il de log4j

Answer 1

Ne vous inquiétez pas pour le contenu de Log4j pour le moment. Cela vous indique simplement que le framework Log4j ne trouve pas sa configuration. Ça va fonctionner sans ça.

La ligne est importante

qui me dit que vous avez une inadéquation de la bibliothèque. Vous avez une bibliothèque dans votre classpath qui ne correspond pas aux exigences d'Axis (probablement une ancienne version de la bibliothèque). Vérifiez les dépendances d'Axis par rapport à ce que vous utilisez (votre version JVM et les bibliothèques de votre chemin de classe).
