Salve a tutti,

Sto cercando di inviare delle notifiche dal mio web server in java ad un client android usando "google Cloud Message".

il client sembra funzionare perfettamente restituisce anche id della registrazione a GCM. Il problema sta nel server java quando tento di avviarlo in localhost con tomcat restituisce questo errore:

Sto seguendo questa guida http://avilyne.com/?p=267.
Anche se nel mio web server uso le api jersey, una volta imparato ad usare GCM, credo di saperlo adattare al mio problema.
qualcuno sa dirmi dove sbaglio?
O sapete suggerimi una guida migliore di questa?


Grazie in anticipo.
