Interface ServletContextEventSource

public interface ServletContextEventSource
This event context is used to register listeners for various servlet context events. These events will be triggered by the servlet engine as appropriate during servlet processing. An implementation of this event context is available to all servlets as a ServletContext attribute by using the ServletContext.getAttribute() method.

Sample Usage (from within a servlet):

 ServletContextEventSource sces = (ServletContextEventSource)getServletContext().getAttribute(
                                 ServletContextEventSource.ATTRIBUTE_NAME);
 sces.addServletErrorListener(myErrorListener);
