HttpSessionActivationListener sessionDidActivate not getting called
This is strange. I did some work few months ago for my application to
manage my sessions using a combination of HttpSessionActivationListener
and HttpSessionListener (not going into the details here as to why I
needed this). When I did that work HttpSessionActivationListener was
working fine and both methods (sessionDidActivate and
sessionWillPassivate) were being called back properly when tomcat was
restarted.
Lately I am seeing that sessionDidActivate() does not get called upon
tomcat restart, even though sessionWillPassivate() is called. Also even
though sessionWillPassivate() is called, I don't see the session
persistence file being created (the one that I specified in
conf/context.xml <context><Manager pathname="xxx"> ).
I also see a bug 48717
(https://issues.apache.org/bugzilla/show_bug.cgi?id=48717) on this
issue. Not sure what's its status is w.r.t. tomcat release 6.0.x. But
the strange thing is that I am on the same version of Tomcat (6.0.20)
where I did the initial work and everything was working properly. What
could have caused this to break?
Looking for suggestions whether upgrading to latest 6.0.x will help or
is it something in my application that's breaking this functionality
(given that it was working before). How can I debug this issue further?

Interestingly, after I moved the <context><Manager> configuration to the
context.xml of the application where I wanted this functionality, its
working again, however I still see multiple attempts to persist
sessions.

RE: HttpSessionActivationListener sessionDidActivate not getting called
Posted by "Aggarwal, Ajay" <Aj...@stratus.com>.
I enabled logging, created 1 session and restarted tomcat. This is what
I see in the logs. Is there anything suspicious here?
Why are there multiple attempts to persist sessions? Is it one per
application? One thing that has changed is now I have multiple
applications. And the path "/shared/httpd/tomcat_sessions" for
persistence is configured in {TOMCAT_BASE}/conf/context.xml, which means
it applies to all apps. So perhaps my 1st app is persisting the session
ok. But 2nd app that has no sessions is overriding the session
persistence file.
I will try by moving this configuration to the application where I
really need this functionality.
Meanwhile can anybody, familiar with this code, validate my theory?

That's the first thing I thought too. However I don't see anything in
the logs to indicate this. Also when sessionWillPassivate() is called I
am logging all session attributes to make sure there is nothing non
serializable there.

Perhaps you are now storing something in the session that is not
serializable. I would expect some log entries indicating such if that's
the case.
