"Expire sessions" button in Tomcat Manager
Hello,
I'm using Tomcat 6.0.32. My app is configured in server.xml file like this:
<Host name="www.myapp.pl" appBase="/usr/lib/tomcat/webapps"
unpackWARs="false" autoDeploy="false"
xmlValidation="false" xmlNamespaceAware="false" >
<Context docBase="/var/www/myapp" path="" cacheMaxSize="5120"
cacheTTL="60000" cachingAllowed="true" >
</Context>
<Context path="/manager" privileged="true"
docBase="/usr/lib/tomcat/webapps/manager">
</Context>
</Host>
In Tomcat Manager, on the application list, there is a button "Expire
sessions" available only for "/manager" application.
How should I configure tomcat to get this button for my application
("/") as well?
Best regards,
Jakub

Thank you for that hint, you're right, it's better way of configuration.
And with this "expire" button show up!

No, better not.

Just a bug. Please file it in Bugzilla.
There is no "Undeploy" button in this case, so maybe the expire one
followed the suit, or maybe just oversight.
Deploying an app by adding it to server.xml is a rare and
non-recommended use case. Why you cannot put them into
conf/www.myapp.pl/ROOT.xml
conf/www.myapp.pl/manager.xml
respectively ?

The command is still there, if you know what URL to invoke. Though you
might want to silence the CsrfPreventionFilter -- see its init-param
named "entryPoints".

Maybe you want to change the value for <session-timeout> in your
web-app's web.xml (or the default one in conf/web.xml)?

Chris,
I checked sources, HTMLManagerServlet.java is the answer.
Button "expire" is showing only if application is deployed, it's
hidden when app is configured with servlet.xml.
Does anybody knows why?
Why I want to expire sessions? Well, actually I need it only for
performance tests. I'm testing application with JMeter, creating a lot
of sessions. When I want to stop test and run the next one - sessions
from first test are still there. I would like to expire them if
they're idle more than 10 minutes.
Bests,
Jakub

Take a look at the manager webapp's source code. I suspect it uses JMX
to inspect the session manager and invalidate each session ... or maybe
the session manager has an "invalidate all sessions" operation you can
perform.
If you don't feel like reading the source, you can write your own
HttpSessionListener, register all sessions that get created (remember to
de-register them when they are invalidated), and then consult that when
you want to expire all sessions.
Why do you want do expire all sessions at once?
