Chris- Thanks. I was under the impression that Tomcat normally explodes the war files when you drop them into the webapps folder, though I know you can disable that feature. I was under the impression that one should run from the exploded directory for performance reasons, i.e. it's faster to pull files from the directory than from inside the war file. If there really is no performance difference, then that's even more reason that I want to get my developers to get this thing down to a war file with no files I need to modify. Thanks again.
