Why do they need to be null?
You're *still* not explaining why you think they should be null - simply
asserting that they are null does not explain why this should be the case.
Please provide an explanation as to why the variable that you have set
to a known value, should suddenly stop being that value and be unset, or
be null.
What is causing it to change?
When you manually shutdown a particular node, you are setting the
MANUAL_STOP attribute to "true" or "1" or some known value.
You only need to know this in the HttpSessionListener so you can
determine whether the sessions are expiring because the node is stopping.
If the value is null, then the node is not being manually stopped, and
so in all probability the sessions are expiring naturally.

If you control the application, then you can always ensure that the
session.invalidate() method is accompanied by your custom log out code.
The other two conditions should be covered by the code described previously.

That makes no sense. These are the logical steps.
1. Manually set an attribute (e.g. MANUAL_STOP=1) in application
scope
2. Manually shutdown Tomcat instance.
3. Tomcat expires all sessions
4. Tomcat fires HttpSessionListener.sessionDestroyed for each session

RE: MISC; Tomcat-5.5.12; After one Tomcat Cluster node shutdown, sessionDestroyed been called before contextDestroyed
Dear Pid,
find below my explanation:
1. Manually set an attribute (e.g. MANUAL_STOP=1) in application scope
2. Manually shutdown Tomcat instance.
3. Tomcat expires all sessions
4. Tomcat fires HttpSessionListener.sessionDestroyed for each session
5. custom code checks for, and finds, attribute (e.g. MANUAL_STOP=1)
if(MANUAL_STOP == null){ // Tomcat Cluster Node Shutdown
//don't do anything
}
else{ // case of session.invalidate or session timeout
6. custom code does logout per session
}
8. Tomcat fires ServletContextListener.contextDestroyed for each app
But in fact, the variable MANUAL_STOP saved to the application scope is always
coming as 1, even after tomcat cluster node shutdown which expected to come as
null.
I need to know if my sessionDestroyed has been called from a session.invalidate
Event OR session timeout OR Tomcat Cluster node shutdown.

Imad Hachem

Re: MISC; Tomcat-5.5.12; After one Tomcat Cluster node shutdown, sessionDestroyed been called before contextDestroyed
@P I didn't want to pollute my deployment process with this manual stuff. So I 'solved' it different for our setup. I do not log users out on sessionDestroy. I only record that they are logged out. Which is overwritten by later logout events. So in the end the data is pretty ok. Not very nice, but nice enough for me. Ronald.

RE: MISC; Tomcat-5.5.12; After one Tomcat Cluster node shutdown, sessionDestroyed been called before contextDestroyed
Hi Imad, You can do everything you like, but it will all be dirty. 1. Set a global variable in your webapp before shutdown of a node. To see If it is a planned shutdown or not. 2. Keep references about the nr. of clusternodes yourself. Can be done quite cleanly with JMX. 3. Do not really logout the user. Only mark a logout time. If another node shuts down or the user really logs out it will overwrite the logout time. And in the end the data is quite correct. (This is what I do.) Everything as pros and cons. Be creative. (I would like to here what works for you.) But the developers of Tomcat think of it as invalidating the Session object (as in java Object) and you and me see it as invalidating the session of the user. This phrase was not very accurate. I meant destroy in stead of invalidating. Because those are different things. Ronald. Op dinsdag, 17 november 2009 16:23 schreef Imad Hachem : Hi Ronald, Thanks for your reply.

Hi Imad, I think also that Tomcat should only invalidate the Session on shutdown if it is the last node in the cluster. But the developers of Tomcat think of it as invalidating the Session object (as in java Object) and you and me see it as invalidating the session of the user. Ronald.

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.

Dear Pid, I have tried that code and didn't helped, note that my context & session variables are not coming as null in order to rely on to be able to differenciate between Tomcat Node shutdown & session.invalidate().

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.
