Subject: Re: [OT] Question on Executor (thread pool)
I am still curious though on when and how to use Tomcat's Executor. I
someone could provide me with a nice example, I would be most grateful.
Tomcat's thread pools used to be on a connector basis, so each had to be sized
for the maximum load expected on the server. Having a single executor shared
by some connectors provides a more consistent way of tuning the server as a
whole, while still allowing an individual thread pool for any connector that
requires it.
To second Chris' comment: sharing a thread pool between Tomcat and the
dedicated needs of your webapp is just asking for trouble. Don't try to force
commonality on things that are unrelated, especially when it's so easy not to.
Thanks for your advise, Chuck. To be honest, I am totally confused now.
I thought it was pretty common to share precious resources across web
apps. Isn't database connection pooling often implemented this way? If
mine isn't, what then would be a good use case for using the shared
class loader?
What is so easy about writing a dedicated service for this?
