Hey I have been following gcm tutorial to create gcm-demo-server and a demo-client.
All was working well on tomcat,

I then uploaded the .war file on a free jsp domain

firstly the page said “No devices registered ”
as soon as I got registered from my android it appeared that 1 device is registered

I pressed the send button to send notification on the device and the server crashed with the following errors
