    All Known Implementing Classes:
    MultiUserChatServiceImpl
    public interface MultiUserChatService
extends org.xmpp.component.Component
    Manages groupchat conversations, chatrooms, and users. This class is designed to operate independently from the rest of the Jive server infrastructure. This theoretically allows deployment of the groupchat on a separate server from the main IM server.

      • getChatRoom

        @Nonnull

             throws NotAllowedException
        Obtains a chatroom by name. A chatroom is created for that name if none exists and the user has permission. The user that asked for the chatroom will be the room's owner if the chatroom was created. Note that when obtaining a room instance using this method, the caller should take responsibility to make sure that any changes to the instance will become visible to other cluster nodes (which is done by invoking syncChatRoom(MUCRoom). Where appropriate, the caller should apply mutex (as returned by getChatRoomLock(String)) to control concurrent access to the returned instance.
        Parameters:
        roomName - Name of the room to get.
        userjid - The user's normal jid, not the chat nickname jid.
        Returns:
        The chatroom for the given name.
        Throws:
        NotAllowedException - If the caller doesn't have permission to create a new room.

Note that when obtaining a room instance using this method, the caller should take responsibility to make sure that any changes to the instance will become visible to other cluster nodes (which is done by invoking syncChatRoom(MUCRoom). Where appropriate, the caller should apply a mutex (as returned by getChatRoomLock(String)) to control concurrent access to the returned instance.
        Parameters:
