Error when stopping or reloading web application
Hi, I got a problem. I always see this at catalina.out everytime I stopped
or reload the web application, what can I do to stop this ? My Application
is Thread based and run behind a web application. When the web application
stopped, it will set the stop value of the Thread as true and will dump
everything on queue to harddrive. Here is the snippet from the catalina.out

Re: Error when stopping or reloading web application
Posted by Leon Rosenberg <ro...@googlemail.com>.
A good solution (or it seems to be one, at least it works for me) is
to have a contextlistener which explicitely stops all custom threads
(even daemon threads).

Re: Error when stopping or reloading web application
Posted by David Delbecq <de...@oma.be>.
I have the same problem here. That's a problem coming from the way
jakarta common logging works together with the way tomcat invalidate
it's webappclassloader before calling the servelt unloading code. When a
class need a logger it does all sort of classloading stuff.
Unfortunately, when you do this during the servlet unloading process,
tomcat concludes the webapp has no intention to stop as it requires new
classes from an invalidated WebappClassLoader (this could also be caused
by a webapp specific thread that did not get close notification). The
main problem with this annoyance is that it deliberatly throw a
ThreadDeathException, breaking you servlet unloading/cleanup code.
Despite what is said on console, it has functional impact. In my case,
this prevented a background Threaded process to stop because, when i try
to logout a 'unloading all currently XXXX threads due to servlet
unloading' i get the exception and byebye the unloading of my own
threads. They stay there. I did remove the logging comments in my
unloading thread to prevent this, but it's still a problem. Some people
may have web application or libraries they have no control on which
cause this kind of exception. Maybe the webappclassloader should be
invalidated *after* all servlet unloading stuff is run and not before??
This is a question to the dev team...
