chatroom

I am using aSmack for creating chat application. When i am creating groupchat by using this aSmack it gives error. this is the code am using for creating GroupChat . MultiUserChat muc = new MultiUserChat(connection, "xyz@abc.com"); try { muc.create(u_name); Form form = muc.getConfigurationForm(); Form submitForm = form.createAnswerForm(); for (Iterator<FormField> fields = form.getFields(); fields.hasNext();) { FormField field = (FormField) fields.next(); if (!FormField.TYPE_HIDDEN.equals(field.getType()) && field.getVariable() != null) { submitForm.setDefaultAnswer(field.getVariable()); } }

I wonder if there is a way to query the XMPP server (passing user JID?) to find out what chat room(s) this user is currently in?

I do not mind paying for something, but I do not want to do any development work whatsoever. thanks in advance. I'm unsure of its maintainership status, but I usually point people

Several visitors connect to http://site.com/chat.php They each can write and send a text message to chat.php and it displays instantly on everyone's browser ( http://site.com/chat.php ) Do I have to use a database? I mean, is AJAX or PHP buffer capabilities enough for such a chat room on sessions? How can sessions of different users share data from each other? Any idea or insights will be appreciated, thanks! Edit: Thanks for the links. But what I want is the way to push data to a client browser. Is constantly refreshing client browser (AJAX or not) the only way? Also the challenge here is how
