erreur service java après demarrage.
Bonjour,
voici l'erreur que j'ai eu quand je demarre le service:
le service ****** sur Ordinateut local a démarré et s'est ensuite arrêté.
Certains services s'arrêtent automatiquement s'ils ne sont pas utilisés par
d'autres services ou programes.
ce service est en fait un .jar fait par une fonction periodique sans fin, je ne sais pas pourquoi ça s'arrête alors !!
en voici le code :
