<listener>

Defines a Listener for the web application.

A listener is notified about various events, such as application or session events.

All listeners are defined the same way. Their function depends on which interface(s) they implement.

Example code demonstrating the <listener> and <listener-class> elements:

• Context Listener example, to listen for application create/destroy events
• Session Listener example, to listen for session create/destroy events
• Session Attribute Listener example, to listen for changes to session attributes
