J'ai appliqué l'événement boundary timer sur la tâche utilisateur, j'ai ajouté java class sur l'attribut de classe de tâche de service mais lorsqu'un délai expiré et une liste d'exceptions déclenchées sont générées par i.e classe assignée à la tâche de service. Bien que la classe existe sur le chemin de la classe. propriété asyncExecutorActivate est également activé dans la configuration ActivitiL'événement timer minuterie déclenche des exceptions
ici est un code
