Group or multiuser chat

Hi, I’‘m trying to figure out how to create some XMPPConnections and join the together in a chat. My program has no user interface, so I don’'t think I need the many features of multiuser chat, but if it is easier, then never mind.

I create two connections and log them in:

conn1.login(username1", “-”);

conn2.login(username2", “-”);[/code]

Then I’'ve tried to do something like:

conn2.addPacketListener(this, null);

GroupChat c = conn1.createGroupChat(“myroom”);


inviteToChat (conn2, c, username2);[/code]

In which the invitetochat method is something I’'ve found in this forum:

private void inviteToChat (XMPPConnection conn, GroupChat chat, final String participant) {

final String user = conn.getUser();

final String host = conn.getHost();

final String room = chat.getRoom();

final String service = conn.getServiceName();

Packet invite = new Packet() {

public String toXML() {

return “<message from=’’“user”@“host”’’ to=’’“participant”’’>” +

“Chat invitation.” +

“<x jid=’’“room”@“service”’’ xmlns=’‘jabber:x:conference’’/>” +






conn2 also get a package, that when i do toXML() on it writes something about “Chat invitation”, but how do I join the chat?[/b]

Hey Thomas,

GroupChat is deprecated and was replaced by MultiUserChat. Remember that both of them require server support so make sure that if you are using MUC then that the server supports it.

You can read the url=http://www.jivesoftware.org/builds/smack/docs/latest/documentation/extension s/muc.htmldocumentation[/url] to learn how to join a room and do other stuffs.

Let us know if you need any help.
