Dan,
Thanks for the post, good ideas I'm going to try them.
One thing I'm still not clear on. My application is
configured to deploy shared modules (jar files) under
CATALINA_HOME/shared/lib.
If I create multiple instances, how do I configure the
apps to share the correct version of
CATALINA_HOME/shared/lib?
Do you create a separate document root that contains a
shared/lib for each <Service> entry in the server.xml
configuration?
