+ +The group chat invitation packet extension is used to invite other +users to a group chat room. + +
+ ++JEP related: N/A -- this protocol is outdated now that the Multi-User Chat (MUC) JEP is available +(JEP-45). 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: + +
+Message message = new Message("user@chat.example.com");
+message.setBody("Join me for a group chat!");
+message.addExtension(new GroupChatInvitation("room@chat.example.com"));
+con.sendPacket(message);
+
+
+The XML generated for the invitation portion of the code above would be:
+
++<x xmlns="jabber:x:conference" jid="room@chat.example.com"/> +
+ +
+ +To listen for group chat invitations, use a PacketExtensionFilter for the +x element name and jabber:x:conference namespace, as in the +following code example: + +
+PacketFilter filter = new PacketExtensionFilter("x", "jabber:x:conference");
+// Create a packet collector or packet listeners using the filter...
