Échec de l'authentification lors de l'envoi de SMS à l'aide de Way2Sms + Java

A essayé d'envoyer des SMS à partir de l'application Java en créant trois classes Java données ci-dessous 1. Pouvoirs 2. URLConnector 3. Way2Sms et l'exécution de la classe Way2Sms, mais l'authentification a échoué! en raison de responseCode est 404 ou 408 dans Way2Sms java méthode de connexion...toute aide pour résoudre ce serait apprécié....
