I need to control openfire users and conversations from my own java application, the number of users is more than 1000 , this is what I want to do exactly :

Listening for new invitations to chat rooms and accept them automaticly ,listening for new messages for all users and listening for presence staus for all users .

As well as I would like to send a new invitation to join a new chat room from specifics users ,send a new message from a user to a chat room and change the presence status of users .

I don't know how I can do that , I tried Smack and it seems that I can only manage or control a single user.

Any help is appreciated

Thanks for your reponse .
