The type Enum is not generic; it cannot be parameterized with arguments <RestClient.RequestMethod>
J'ai cette erreur dans le code suivant ..Le type Enum n'est pas générique; il ne peut pas être paramétrés avec des arguments <RestClient.RequestMethod>

quel est le problème ??? !
c'est réglé à 1,6 – Adham
C'est étrange. Quelle plateforme utilises-tu? Faites une expérience simple en commentant l'enum et en utilisant une fonctionnalité Java 1.5 (une méthode varagrs par exemple: private myMethod (String ... args). – kgiannakakis
non non, c'est résolu .. savez-vous comment j'ai couru un autre projet .. et l'erreur a été résolue – Adham
