This set of examples, of which this is the first, show how to build a basic XMPP based chat in Actionscript 3 by using the XIFF library from Ignite Realtime.
You will need a recent copy of the XIFF library. You can get it with a Subversion client:
svn co -r 11106 http://svn.igniterealtime.org/svn/repos/xiff/trunk/src/org orgThe example code below demonstrates a simple chat with anonymous login. You can compile it for example with Adobe Flex 3 SDK.
API documentation for the library can be found at paazio.wippiespace.com/xiff3doc.

}Make sure anonymous logins are allowed on the server you are trying to connect with this script. Also remember to set _chattingWith into something more appropriate, this is the other person in your instant messaging.
