How to get Openfire user presence in the chat room

Question

I am using Openfire 3.10.2 XMPP server and Strophe library as client. I want to send messages via push notification to all the users in the chat room who did not join the chat room.

Is there any plugin for it ?

Are the user presence in the chat room saved in database ? How can I achieve this ?

You said you would send messages to users IN the chat room who did NOT JOIN the chat room: it seems a contraddiction. If a user doesn't join a room he isn't IN the room and so there's no way to send messages exchanged in the room also to this user.

Regarding room presence you don't need a plugin, but you can relay on a presence handler attached to Strophe.connection. Here is an example:

connection.addHandler(onPresence, null, "presence");

...

function onPresence(presence) {
    var msg = $(presence);
    if (msg.children('x[xmlns^="' + Strophe.NS.MUC + '"]').length > 0) {
        // muc presence
        onRoomPresence(presence);
    } else {
        // user presence
        onUserPresence(presence);
    }
    return true;
}

However, there is also a Strophe plugin named MUC (see strophe.muc.js)
