XMPP client in Flex with ActionScript 3

Leave a comment

I would like to share some knowledge that I have done for XMPP client in Flex with ActionScript 3.
For ActionScript 3, you must download XIFF API 3.0 from http://www.igniterealtime.org.
Here is the sample code that you can follow to create XMPP client in Flex with ActionScript 3.
For run this sample code, you must have account in XMPP Server like OpenFire or Ejabberd.

Create account name “sinal” and one more “lee” in XMPP Server.


<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="initApp()">
	import mx.controls.Alert;
	private var xmpp:XMPPSocket = new XMPPSocket();
	public function initApp():void
		btnConnect.addEventListener(MouseEvent.CLICK, connectEvent);
		btnConnect.addEventListener(KeyboardEvent.KEY_DOWN, connectEvent);	
		txtMsg.addEventListener(KeyboardEvent.KEY_UP, keyUp);		
	public function connectEvent(event:Event):void
	public function messageSend():void
		var msg:String = txtMsg.text; 
		var jid:String = "lee@seven-pc";
		xmpp.sendMessage(jid, msg);
		txtMsg.text = "";
	public function keyUp(event:KeyboardEvent):void
                case Keyboard.ENTER :

	<mx:State name="ConnectedState">		
		<mx:AddChild relativeTo="{form1}" position="lastChild">
			<mx:VBox width="422" height="179" id="vbox1">
			<mx:TextArea width="422" height="145" id="textTalk">						
					<mx:Label text="Message:"/>
					<mx:TextInput width="289" id="txtMsg" keyUp="keyUp(event)"/>
					<mx:Button label="Send" id="btnSend" click="messageSend()"/>
		<mx:SetProperty target="{formitem1}" name="label" value="Status:"/>
		<mx:RemoveChild target="{formitem1}"/>
		<mx:AddChild relativeTo="{vbox1}" position="before" target="{formitem1}"/>
		<mx:RemoveChild target="{btnConnect}"/>
		<mx:AddChild relativeTo="{form1}" position="lastChild" target="{btnConnect}"/>

<mx:Form width="455" height="263" id="form1" horizontalCenter="-28" verticalCenter="-29">

Chat with Jabber.org

Leave a comment

So far, I have used the chat with yahoo, google, skype and IRC. Fortunately now I have found one free chat service typically called Jabber Chat Service.
For Jabber Chat Service, you just go to http://jabber.org and set up one account for jabber id in order to communicate with other people who use XMPP protocol chat client like google.
And then you can use your jabber id with PSI XMPP chat client or other XMPP chat client like SamePlace, Gtalk and so on.

The XMPP service offered at jabber.org is the original and longest-running XMPP service on the Internet. In the beginning, the jabber.org service served as the development testbed for the jabberd server project. After the release of jabberd 1.0 in May 2000, the jabber.org service became more stable and thus more popular with end users. The userbase has continued to grow, from perhaps 500 users in late 1999 to over 500,000 users in April 2009. Clearly the service is no longer experimental, and considerable attention is needed to maintain an acceptable level of functionality and performance.
