Can anyone tell me what I am doing wrong?

This code example works fine!

I think this is a problem with your jabber server!

Yeah, jabberd doesn’‘t support multi user chat (=group chat) by default, you’'ll have to install the jabberd component runtime and then install the mu-conference. of course this all only helps if you use Jabberd as your Jabber Server, other servers may support multiuser chat by default. maybe you could try to login to your groupchat with a normal client, just to check if it works.



Thanks dude.
