They are called when the appropriate event occurs. ServletContextListener reacts to changes in the servlet context og the applciation (e.g. Servlet initialisation). ServletRequestListener reacts to requests. HttpSessionListener reacts to session creation/deletion events.

As already mentioned the listener is called when the appropriate event occurs. So, obviously a servlet context event listener will be called before a servlet request or session event listeners. [ September 29, 2008: Message edited by: Bosun Bello ]
