Example 1 with MUCInitialPresence

use of org.jivesoftware.smackx.packet.MUCInitialPresence in project ecf by eclipse.

the class MultiUserChat method create.

/**
 * Creates the room according to some default configuration, assign the requesting user
 * as the room owner, and add the owner to the room but not allow anyone else to enter
 * the room (effectively "locking" the room). The requesting user will join the room
 * under the specified nickname as soon as the room has been created.<p>
 *
 * To create an "Instant Room", that means a room with some default configuration that is
 * available for immediate access, the room's owner should send an empty form after creating
 * the room. {@link #sendConfigurationForm(Form)}<p>
 *
 * To create a "Reserved Room", that means a room manually configured by the room creator
 * before anyone is allowed to enter, the room's owner should complete and send a form after
 * creating the room. Once the completed configutation form is sent to the server, the server
 * will unlock the room. {@link #sendConfigurationForm(Form)}
 *
 * @param nickname the nickname to use.
 * @throws XMPPException if the room couldn't be created for some reason
 *          (e.g. room already exists; user already joined to an existant room or
 *          405 error if the user is not allowed to create the room)

Example 2 with MUCInitialPresence

use of org.jivesoftware.smackx.packet.MUCInitialPresence in project ecf by eclipse.

the class MultiUserChat method join.

/**
 * Joins the chat room using the specified nickname and password. If already joined
 * using another nickname, this method will first leave the room and then
 * re-join using the new nickname.<p>
 *
 * To control the amount of history to receive while joining a room you will need to provide
 * a configured DiscussionHistory object.<p>
 *
 * A password is required when joining password protected rooms. If the room does
 * not require a password there is no need to provide one.<p>
 *
 * If the room does not already exist when the user seeks to enter it, the server will
 * decide to create a new room or not.
 *
 * @param nickname the nickname to use.
 * @param password the password to use.
 * @param history the amount of discussion history to receive while joining a room.
 * @param timeout the amount of time to wait for a reply from the MUC service(in milleseconds).
 * @throws XMPPException if an error occurs joining the room. In particular, a
 *      401 error can occur if no password was provided and one is required; or a
 *      403 error can occur if the user is banned; or a
 *      404 error can occur if the room does not exist or is locked; or a
 *      407 error can occur if user is not on the member list; or a
 *      409 error can occur if someone is already in the group chat with the same nickname.
