Bonjour
Les messages d'erreur qu’affiche-la console sur Eclipse; je ne suis pas familier avec OSGI equinox et je n'arrive pas à comprendre d'où vines le problème !!

Voilà une capture de ce que j'ai fait (avec le fichier MANIFEST qu’utiliser pour l’exécution)


Aussi le message d'erreur

Merci de votre aides !

Salut,

L'erreur n'a rien à voir avec OSGI : tu invoques une méthode sur la variable context non initialisée.

Ajoute context=bundleContext avant la ligne qui plante !
