How To Register Google App Engine To Xmpp Client?

I am using psi to test the xmpp service in my app engine project. when I open psi, it asks me to enter the name of the server I wish to register with. I tried my_app_id.appspotchat

Solution 1:

The server is talk.google.com. And you have to connect to it through port 5222.

Your App Engine application will act just as an endpoint for XMPP packets, i.e. to send/receive presence and message packets, not as a server itself.
