My GAE application has a server-side program (run in Google App Engine) and a client-side program. Is there any elegant way to send message from the server to the client program? The socket is not allowed in GAE and the channel API is not applicable since the client program is not a browser. The only way I can think of is to let the client program check the server status from time to time (like every 5 seconds). The program is that it eats up the expensive frontend instance hours even only memcache is used. Any suggestions? Thanks!

You can do this via XMPP API. https://developers.google.com/appengine/docs/java/xmpp/overview
