Hi,
I'm building a small instant messaging application (yes I know there are plenty out there, it's merely for educational purposes).
I already found a solution (storing values / messages in // retrieving values / messages from a singleton ejb), so no need for JMS.
(JMS would also bring the headache of how to notify the receiving client, since most clients will sit behind a NAT or firewall.. So I can't do "push".. instead I settled for quartz-scheduled polling)
Thanks for your response anyway =)
