I am a beginner and need help.
I am currently involved in a project, where required to build a chat application (server side and client side). After further explore, eventually I was interested in XMPP.
For XMPP Server, I have been interested in the Openfire, which support XMPP Protocol. The question that remains unanswered is whether Openfire can be extended to the needs of Message Notification, which is a feature of the Blackberry Messenger which can determine whether a message is PENDING, DELIVERED, or has been READ by the client (user).
Can anyone help me?
