Callback by java application in J2ee Server

Hi all

I need to pass the client reference in a java application(Not web app) to thebean,whether it is session, entity or message, and allow the bean tocallback the client(by invoking the method located at the client side or another mean) when some event is happened. Is it possible? and how to do it?
