I get following error when trying to send a message from GCM demo server. The code is same as supplied at developer.android.com/google/gcm/demo.html and it's run on Tomcat. The device gets registered on the server and shows "1 device(s) registered!". But i get following error when "send message" button is pressed. (I have placed the api key i received from https://code.google.com/apis/console/ in "api.key" file.)

Apache Tomcat/7.0.35 - Error report

HTTP Status 500 - HTTP Status Code: 401

type Exception report

message HTTP Status Code: 401

description The server encountered an internal error that prevented it from fulfilling this request.
