Hi,
Nice topic. Very few people are working on XIFF
a) I want to populate all the groups on openfire 3.7 server from XIFF……how can i do that? the groups are not shared……RosterGroup is giving only groups to which current user is registered.
b) How to implement searching a user based on his name…..with XIFF…i have been trying Search Extension but no success……can u help please…

Hi Mark! Thank you for your good topic.

Can you write some your UserExtension class code?
And code for use this class in project?

Thank you.

HI Mark,
This is very useful post. Actually I am working on XMPP, I have a doubt. I need to pass some data to my roster (company, userEmail etc.). So I created a custom Extension.
package net.firstcourt.Extensions
{
import flash.xml.XMLNode;

import net.firstcourt.GlobalConst;

import org.jivesoftware.xiff.data.Extension;
import org.jivesoftware.xiff.data.ExtensionClassRegistry;
import org.jivesoftware.xiff.data.IExtension;
import org.jivesoftware.xiff.data.ISerializable;

public class UserExtension extends Extension implements IExtension, ISerializable
{
public static var NS:String = GlobalConst.SERVER + “/UserExtension”;
public static var ELEMENT:String = “userData”;

public var companyName:String;
private var myNode:XMLNode;

public function UserExtension( parent:XMLNode=null )
{
super( parent );
myNode = parent;
//myNode = new XMLNode(1, ‘company’);
//myNode.nodeValue = “myCom”;

}

public function getNS():String
{
return NS;
}

public function getElementName():String
{
return ELEMENT;
}

public function serialize( parentNode:XMLNode ):Boolean
{

parentNode.appendChild(myNode);

return true;
}

public function deserialize( node:XMLNode ):Boolean
{
setNode(node);

var children:Array = getNode().childNodes;
for( var i:String in children ) {
switch( children[i].nodeName )
{
case “company”:
companyName = children[i];
break;

}
}
return true;
}
public static function enable():void
{
ExtensionClassRegistry.register(UserExtension);
}

}
}

and I tried to connect with room
var myNode:XMLNode = new XMLNode(1, ‘company’);
myNode.nodeValue = “myCom”;

var userExtension:UserExtension = new UserExtension(myNode);
var message:Message = new Message();
message.addExtension(userExtension);

xmppSocketConnection.send(message);

var joined:Boolean = room.join(false,[userExtension]);
is this right?
from where I can get the company?

please help me.

Thanks
Roy

Hi,
I have a single problem, when I connect to server chat, after 6 or 7 minutes, the chat is disconnect from server and I don’t know why. Do someone have the solution?

Hey Gianluca,

I appreciate the kind words!
Unfortunately, the extension that I wrote is tied very tightly to my company’s chat rooms so I can’t share the code.
But if you have any specific questions, ask them here and I’ll respond as best I can.

Wow. All of my best compliments for your write-up. The XIFF project is really an amazing library, but it lacks of enough people talking about it. Soon I will finish my project with XIFF. I did have few issues finding out things by myself, especially since I am not a programmer (I am a frontend developer).

Although I succeeded to work out user self-registration, room creation/configuration, and the presence, even though I DID fail trying to achieve what you did.

Is there any way you could share your extention code with us? If not, I’ll understand. Anyhow, great work! Keep it up.
