Action on close
Hello,
it is possible to specify a class what must be called (loaded) on startup
(web.xml, <servlet> <load-on-startup> ...). It is working fine.
My question is it possible to specify any servlet what will be loaded before
Tomcat shutdown?
Thanks in advance

You're right and that's what I said. Jake got the right answer.
BTW why 'Death to all load on startup servlets'? Personal preference?

You can't rely on the destroy() method on the servlet for this purpose. The
container has the right to unload servlets when it chooses as a part of
resources management. If you are using a servlet 2.3 spec container use the
ServletContextListener as Jake suggests.

Yep,
Servlet 2.3 introduced the concenpt of the ServletContextListener which
contains
contextInitialized() and contextDestroyed() which are guaranteed to be
loaded
once at startup and once at shutdown, respectively.
You just need a class that implements ServletContextListener and specify it
in
the web.xml as:
<listener>
<listener-class>
org.myapp.listeners.MyServletContextListener
</listener-class>
</listener>
There you go.

There's a destroy() method called on a servlet when it is unloaded from
Tomcat. You can't depend on that to mean that Tomcat is shutting down
but maybe it could be helpful.
