A framework for event-driven demonstration based on the Java toolkit

An event-driven demonstration shows the behavior of an application by re-executing the captured events. It is used to provide help regarding how an application works because it can show typical behaviors in an effective way. Such help functions are needed in Java applets, which are carried out by everyone using a Web browser. We describe a framework in which we can execute the event-driven demonstrations of Java applets. We have developed Jedemo recorder and player. The Jedemo recorder captures the occurring events while the applet is running. To make the demonstration more efficient and understandable, the developer can add indexes and messages to the captured events. Then Jedemo player re-executes the captured events showing also the indexes and messages that were added to them. The Jedemo recorder and player suits almost all applets. They are implemented as applets. The developer can integrate his applet with Jedemo player without any trouble. This framework is helpful for both the developer of the applets and the person who accesses the applets
