HTTPSessionActivationListner doubt

[prashant k. gupta]

Is HTTPSessionActivationListner required to mention in DD? please explain.

Thanks

No ... same applies for HttpSessionBindingListener.

Behind the scenes something like this happens:

1. It is iterated through all session attributes
2. A if(attribute instanceof HttpSessionActivationListener) is performed.

Hi Sebastian ,

i found this in HFSJ 1.4 that except HttpSessionBindingListener, all listners need to be configured in DD. was there any changes or errata on that?

Check This URL: http://edocs.bea.com/wls/docs61/webapp/app_events.html#176479

It states:

Note: The Servlet 2.3 specification also contains the javax.servlet.http.HttpSessionBindingListener and the javax.servlet.http.HttpSessionActivationListener interfaces. These interfaces are implemented by objects that are stored as session attributes and do not require registration of an event listener in web.xml. For more information, see the Javadocs for these interfaces.
