Dear Pid,
I have tried to set application context variables, but it didn't worked, since
I m expecting to get these variables as null values after node shutdown, but in
fact they are coming as not null.
If you set them as "not null" and they are "not null" why are you surprised?
Why do you expect them to be null?

Hi Imad,
Ronald. (The Ronald of the link mentioned by Pid.)
Did the code supplied therein, work for you Ronald?
@Imad
The Servlet Spec (and therefore Tomcat) doesn't differentiate between
causes of session expiry.
The code requires you to set a value in the application scope, then the
HttpSessionListener sessionDestroyed method checks for that value.
If the value is present, you initiated shutdown. If it is not, then
it's probably a session expiry and you run your logout code.
Did you actually set such an attribute?

Dear Pid,
I am running a Logout Process at each sessionDestroy.
After applying the Cluster configuration, I don't want to Logout my
Users (or run this Logout Process) after any Tomcat Cluster node
shutdown, since the Session has been replicated to the other Node
Cluster.

I'm sorry but I don't understand what you're saying here.
Tomcat& the servlet api can't tell you the difference between an app
shutdown and a session expiry without you writing code.
What did you try?
What was or wasn't null exactly?

Dear Pid,
Thanks for your reply.
But can you specify exactly which Servlets API method to use?
The link I sent had some code in it, did you read it?
Note that Tomat-5.5.12 is deployed on Production environment and
we are not facing major issues.
But you might be facing some security ones.
I will appreciate if you can adivse to which Tomcat Stable version
we should Migrate taking in consideration that Tomcat Cluster is
used in our environment as well.
The latest: Tomcat 5.5.28. Same app, many bugfixes. Your version was
released September 2005, over 4 years ago (that's 28 internet
years).
It's not good practice to avoid upgrading for that long.

Dear all,
I am using Tomcat-5.5.12 as Clustering nodes, and after one node
shutdown sessionDestroyed is called before contextDestroyed.
Are you still using 5.5.12? Hasn't anyone advised you to upgrade
to a
newer version yet?
I think it's perfectly reasonably to call sessionDestroyed()
before
contextDestroyed().
How can I know if sessionDestroyed is called from
session.invalidate()
from the real expiration of the session or shutdown of one
cluster node?
You can't know this directly from the Servlet API methods.
Note that on sessionDestroyed event, I am using a Logout
behavior to
logout my users from the DATABASE.
I have tried to set a KEY on the context (or application scope)
to check
on it during the sessionDestroyed event, but it seems the
context is
destroyed after the session destroy event.
This comes up not infrequently on the list, the archives have more
information:
http://old.nabble.com/Re%3A-sessionListener.sessionDestroyed-is-called-on-shutdown-of-a-node-in-the-cluster-p16746969.html
Is there any event listener that I can use before the
sessionDestroyed to differentiate if one cluster node has been
shutdown or my session has been expired?
Or is how to configure the contextDestroy to be called before
the sessions destroy?
No, contextDestroyed() means that the web application itself has
been
stopped, this is mandated by the Servlet Spec.

Thanks in advance for your help.
