About XMPP Chat server

XMPP is Extended Messaging and Presence Protocol. As the name suggests it is used for (instant)

messaging. It gives the presence of the other users. Whatsapp, Google chat etc use XMPP Protocol.

I have used Smack API for client side coding and Ejabberd as the server.

If you want to add some functionality in server, learn some erlang and write your hooks in

Ejabberd Server. Its easy! And you will get a lot of help online.

I have an extremely simple hook examples on : Writing your own ejabberd Module

I have to add a few details on the blog, but its good for a start.

XMPP is really fast. Read on ejabberd.yml too!
