Method Detail

onSessionCreated

protected void onSessionCreated(org.exoplatform.container.ExoContainer container,
                                javax.servlet.http.HttpSessionEvent event)

This method is called when a HTTP session of a Portal instance is created. In this method, we: 1) first get the portal instance name for which the session is created. 2) Put the portal instance in the Portal ThreadLocal 3) Broadcast the SESSION_CREATED event 4) Flush the ThreadLocal for the PortalContainer

Specified by:

onSessionCreated in class org.exoplatform.container.web.AbstractHttpSessionListener

onSessionDestroyed

protected void onSessionDestroyed(org.exoplatform.container.ExoContainer container,
                                  javax.servlet.http.HttpSessionEvent event)

This method is called when a HTTP session of a Portal instance is destroyed. In this method, we: 1) first get the portal instance name for which the session is created. 2) Put the portal instance in the Portal ThreadLocal 3) Broadcast the SESSION_DESTROYED event 4) Flush the ThreadLocal for the PortalContainer

Specified by:

onSessionDestroyed in class org.exoplatform.container.web.AbstractHttpSessionListener

contextDestroyed

public void contextDestroyed(javax.servlet.ServletContextEvent event)

This method is called when the ServletContext of the Portal is destroyed. In this method, we: 1) first get the portal instance name for which the session is created. 2) Put the portal instance in the Portal ThreadLocal 3) Broadcast the CONTEXT_DESTROYED event 4) Flush the ThreadLocal for the PortalContainer

Specified by:

contextDestroyed in interface javax.servlet.ServletContextListener

contextInitialized

public void contextInitialized(javax.servlet.ServletContextEvent event)

This method is called when the ServletContext of the Portal is initialized. In this method, we: 1) first get the portal instance name for which the session is created. 2) Put the portal instance in the Portal ThreadLocal 3) Broadcast the CONTEXT_INITIALIZED event 4) Flush the ThreadLocal for the PortalContainer

Specified by:

contextInitialized in interface javax.servlet.ServletContextListener
