Hi Monojit -
This is certainly possible, and there are several different ways to do it. Probably the easiest is to create and maintain the hastable on the RMI server program, and make it accessible remotely to any clients.
If you want the client to be updated as hashtable modifications (e.g., "events") occur, a remote event-handling system can do the trick for you.
Look through the back issues of
Java Report Online -- there are several useful articles on remote event-handling systems.
