I have a class that does some network polling. This class implements observable. It updates a datastructure after every poll and notify all its observers. These observers are used to periodically refresh my GUI client. This works fine in case of a simple java application. When I tried to port this to servlets, I am not able get the same functionality done. Is it because servlets cant be an observer ? Someone please throw some light on this. Regards, Dhanush
