Class WebApplicationListener

java.lang.Object

to.etc.iocular.web.WebApplicationListener

All Implemented Interfaces:

EventListener, javax.servlet.http.HttpSessionListener, javax.servlet.ServletContextListener, javax.servlet.ServletRequestListener

public class WebApplicationListener
extends Object
implements javax.servlet.ServletContextListener, javax.servlet.http.HttpSessionListener, javax.servlet.ServletRequestListener

This listener must be registered as a 'listener' entry in web.xml for any webapp that requires the use of the iocular container. An example config would be:

                        to.etc.iocular.web.WebApplicationListener
                
 ]]>
 

 
This receives info when the web application starts and when it ends; this creates
 the web- and session-scoped containers.
