Using Openfire with Google App Engine

Hi there,

i am going to develop a cross platform chat app which use xmpp and i am using openfire server for it, i have decided to deploy application on googe app engine. I have read that openfire cannot be installed on app engine, so you will have to install it on another server and then connect it with google app engine.

Please instruct me what i read was correct? If so then how i can do this.
