You could have all of your JSP's check for the presence of an application variable. If the variable is found, a JavaScript popup window can be made to appear the next time the server sends a response and the appropriate message can be displayed. Note that the message will only appear once a client makes a request to the server. If a client doesn't send a request to the server between the time that you decide to send the message and the time you shut the server down, they won't get a notification. There are other things you could possibly do such as run applets on the client's browser and have the server send messages to the applets, but I personally don't think it is worth the trouble and added overhead.
