We added a GenericHttpListener that allows you to define new HttpSessionListeners and/or ServletContextListeners thanks to an external plugin. Actually, the GenericHttpListener will broadcast events thanks to the ListenerService that you can easily capture. The events that it broadcasts are:

If you want to listen to org.exoplatform.web.GenericHttpListener.sessionCreated, you will need to create a Listener that extends _Listener<PortalContainer, HttpSessionEvent>_If you want to listen to \_org.exoplatform.web.GenericHttpListener.sessionDestroyed_, you will need to create a Listener that extends _Listener<PortalContainer, HttpSessionEvent>_If you want to listen to \_org.exoplatform.web.GenericHttpListener.contextInitialized_, you will need to create a Listener that extends _Listener<PortalContainer, ServletContextEvent>_If you want to listen to \_org.exoplatform.web.GenericHttpListener.contextDestroyed_, you will need to create a Listener that extends Listener<PortalContainer, ServletContextEvent>

See an example of Session Listener below:

..

import org.exoplatform.container.PortalContainer;

import org.exoplatform.services.listener.Event;

import org.exoplatform.services.listener.Listener;


import javax.servlet.http.HttpSessionEvent;


public class SampleHttpSessionCreatedListener extends Listener<PortalContainer, HttpSessionEvent>

{


   @Override

   public void onEvent(Event<PortalContainer, HttpSessionEvent> event) throws Exception

   {

      System.out.println("Creating a new session");

   }

}

See an example of Context Listener below:

..

import org.exoplatform.container.PortalContainer;

import org.exoplatform.services.listener.Event;

import org.exoplatform.services.listener.Listener;


import javax.servlet.ServletContextEvent;


public class SampleContextInitializedListener extends Listener<PortalContainer, ServletContextEvent>

{


   @Override

   public void onEvent(Event<PortalContainer, ServletContextEvent> event) throws Exception

   {

      System.out.println("Initializing the context");

   }

}
