Finalizing classes in common or shared directories

[Tushar Madhukar]

Hello,

I have several contexts running in Tomcat(5.5.23), which use some common
utilities. Classes for these utilities are in shared/ directory of the
Catalina installation.
Is there a way by which Tomcat can invoke a callback on these classes
(shared/*) when it is shutting down? I need this to perform cleanups.
Basically, I would use an equivalent of
ServletContextListener.contextDestroyed() callback in deployed contexts. I
failed to stumble upon any useful googled info.

Thanks
