Abstract: Methods and systems for inter-applet communication. The methods and systems of the invention are particularly useful for communication between applets in different frames of an HTML page. Java and HTML specifications generally preclude interaction between applets in different HTML pages or frames. The present invention permits such communication by defining a superclass from which all such communicating applets are specialized. The superclass includes static structures and associated methods for enabling communication between the applets specialized therefrom. A static notification list has entries each of which identify a particular applet which requires notification of events from other applets. A first method of the superclass, invoked by a second applet desiring notification of an event, adds (or removes) entries in the notification list.
