[jdev] XMPP doubt

[vitor at easyclick.pt]

Hi all!!!

I'm using jabberd to develop a mobile application.

When i send an invitation to a friend, he receives a notification. If he
does nothing (accept/deny) and logout, when he login again the invitation
doesn't appear, although in database we are not subscribed to each other.

this notification only apears once?

where can i find more information about that?

thanks in advance!!!
