Can I get some ideas about how to combat a user repeatedly clicking a button effectively launching a DOS attack on the app! How can I limit the number of clicks (within a reasonable time frame of course) to prevent this happening?

Cant you just have a member, "clickButton = false" set to "true" when teh button is clicked, and check if its false before starting the action?

You can also inherit JButton and override the fireActionPerformed() and fireItemStateChanged() methods, to fire only once per limited time frame, or at all.

You could do it in the actionPerformed () method itself. Maintain a record of the last-time when the button was clicked. Use getSource () to check if the button-source is same and search for its last-click-time. If the current-time is within some predefined time-frame, ignore the click and exit the method.
