Create a Room
There are two types of rooms that you can create.
Instant rooms which are available for immediate access and are automatically created based on some default configuration.

MultiUserChatManager manager = MultiUserChatManager.getInstanceFor(connection); MultiUserChat muc = manager.getMultiUserChat("myroom@conference.jabber.org"); // Create the room muc.create("testbot"); // Send an empty room configuration form which indicates that we want // an instant room muc.sendConfigurationForm(new Form(DataForm.Type.submit)); |
Reserved rooms- which are manually configured by the room creator before anyone is allowed to enter.

MultiUserChat muc = =manager.getMultiUserChat("myroom@conference.jabber.org"); // Create the room muc.create("testbot"); Form form = muc.getConfigurationForm(); // Create a new form to submit based on the original form Form submitForm = form.createAnswerForm(); for(Iterator fields = form.getFields(); fields.hasNext();) { FormField field = (FormField) fields.next(); if (!FormField.type.hidden.equals(field.getType()) && field.getVariable() != null) { // Sets the default value as the answer submitForm.setDefaultAnswer(field.getVariable()); } } // Sets the new owner of the room List owners = new ArrayList(); owners.add("johndoe@jabber.org"); submitForm.setAnswer("muc#roomconfig_roomowners",owners); muc.sendConfigurationForm(submitForm); |
Join the Room- Your usual first step in order to send messages to a room is to join the room. Multi User Chat allows to specify several parameter while joining a room. Basically you can control the amount of history to receive after joining the room as well as provide your nickname within the room and a password if the room is password protected.
