I took the first shot at implementing the new GCM CCS server on GAE using
the Smack library for XMPP. Here is more documentation -
https://developer.android.com/google/gcm/ccs.html
However, I got below exceptions. I do have smack.jar, smackx.jar in
WEB-INF/lib directory (although only smack.jar is required).

On further investigation, I found that XMMP client implementation on
GAE server requires a socket to be opened. There is a way to open a
socket from GAE using Open Socket API -
https://developers.google.com/appengine/docs/python/sockets/overview
However my question is, do we need to implement XMPP client library
from scratch? Or has anybody used a XMPP client library on GAE server
successfully?
I am sure lot of developers are interested in this answer.
