The group chat invitation packet extension is used to invite other
|
|
users to a group chat room.

<b>XEP related:</b> N/A -- this protocol is outdated now that the Multi-User Chat (MUC) XEP is available
|
|
(<a href="http://www.xmpp.org/extensions/xep-0045.html">XEP-45</a>). However, most
|
|
existing clients still use this older protocol. Once MUC support becomes more
|
|
widespread, this API may be deprecated.

To use the GroupChatInvitation packet extension
|
|
to invite another user to a group chat room, address a new message to the
|
|
user and set the room name appropriately, as in the following code example:
|
|
|
|
<pre>
|
|
Message message = new Message(<font color="#0000FF">"user@chat.example.com"</font>);
|
|
message.setBody(<font color="#0000FF">"Join me for a group chat!"</font>);
|
|
message.addExtension(new GroupChatInvitation(<font color="#0000FF">"room@chat.example.com"</font>));
|
|
con.sendPacket(message);
|
|
</pre>
|
|
|
|
The XML generated for the invitation portion of the code above would be:
|
|
|
|
<pre>
|
|
<x xmlns="jabber:x:conference" jid="room@chat.example.com"/>
|
|
</pre><p>
|
|
|
|
<hr>
|
|
<div class="subheader"><a name="listen">Listening for Invitations</a></div><p>
|
|
|
|
To listen for group chat invitations, use a PacketExtensionFilter for the
|
|
<tt>x</tt> element name and <tt>jabber:x:conference</tt> namespace, as in the
|
|
following code example:
|
|
|
|
<pre>
|
|
PacketFilter filter = new PacketExtensionFilter(<font color="#0000FF">"x"</font>, <font color="#0000FF">"jabber:x:conference"</font>);
|
|
<font color="#3f7f5f">// Create a packet collector or packet listeners using the filter...</font>
|
|
</pre>
