Class StartupManager

java.lang.Object

edu.cornell.mannlib.vitro.webapp.startup.StartupManager

All Implemented Interfaces:

EventListener, javax.servlet.ServletContextListener

public class StartupManager
extends Object
implements javax.servlet.ServletContextListener

Instantiate and run the ServletContextListeners for Vitro, while accumulating messages in StartupStatus. The startup listeners are stored in a file with one full-qualified class name per line. Blank lines and comment lines (starting with '#') are ignored. No exception in the listeners should prevent the successful completion. However, an uncaught exception or a fatal error status will cause the StartupStatusDisplayFilter to disply the problem instead of showing the home page (or any other requested page).

contextInitialized

public void contextInitialized(javax.servlet.ServletContextEvent sce)

public void contextDestroyed(javax.servlet.ServletContextEvent sce)

Notify the listeners that the context is being destroyed, in the reverse order from how they were notified at initialization.
