Create new MUC on the server

Is it possible to create a new MUC on the server? Like the account with the account manager it is possible to create a new account on the server. I want to create a new MUC on the server… But how…

With

MultiUserChat muc = new MultiUserChat(conn, “conference.”+server);

its just possible to create an object…

sure

just do muc#create

At the point I am calling MultiUserChat#create, I get a “no response from server” error. Did I miss something? For example, room names must follow certain conventions or something like that?

FYI: I am connecting to “jabber.org” using an account JID: "oraoraoraoraora@jabber.org"
