Group Chat Invitations

======================

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

**XEP related:** N/A -- this protocol is outdated now that the Multi-User Chat (MUC) XEP is available ([XEP-45](http://www.xmpp.org/extensions/xep-0045.html)).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

Inviting Other Users
|
|
--------------------
|
|
|
|
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:
|
|
|
|
```
|
|
Message message = new Message("user@chat.example.com", "Join me for a group chat!");
|
|
message.addExtension(new GroupChatInvitation("room@chat.example.com"));
|
|
con.sendStanza(message);
|
|
```
|
|
|
|
The XML generated for the invitation portion of the code above would be:
|
|
|
|
```
|
|
<x xmlns="jabber:x:conference" jid="room@chat.example.com"/>
|
|
```
|
|
|
|
Listening for Invitations
|
|
-------------------------
|
|
|
|
To listen for group chat invitations, use a StanzaExtensionFilter for the `x`
|
|
element name and `jabber:x:conference` namespace, as in the following code
|
|
example:
|
|
|
|
```
|
|
StanzaFilter filter = new StanzaExtensionFilter("x", "jabber:x:conference");
|
|
// Create a packet collector or packet listeners using the filter...
|
|
```
