Welcome to Apache Vysper at Apache Labs

What is it?

Vysper aims to be a full blown XMPP (=eXtensible Messaging and Presence Protocol) server.
The core of XMPP is defined in the standards RFC3920 and RFC3921.

XMPP is more commonly known as 'Jabber'.

IMPORTANT NOTE: Vysper has moved. It is now a subproject of Apache MINA. This content will soon be moved, too.
