Class JDOApplicationListener

java.lang.Object
  com.sptci.echo.http.ContextListener
      com.sptci.echo.http.JDOApplicationListener

All Implemented Interfaces:

EventListener, HttpSessionListener, ServletContextListener

public abstract class JDOApplicationListener
extends ContextListener

A ServletContextListener and HttpSessionListener to close JDO resources that are held by the JDOApplication instance or its subclasses.

Since a web container usually allows only one instance of a context listener, this class is made abstract. You must create at the very least a dummy sub-class of this listener for your application and use as the listener for your application.
