But it does. I've made the change it it works.

Classes loaded from jars in a web app's WEB-INF/lib *DO* see into the
app's WEB-INF/classes directory. I've have it working. As I said before,
if I change "Object" to "Category" in the static initializer in
Category.java then
the following two situations work just fine:
- log4j.jar in WEB-INF/lib and log4j.properties in WEB-INF/classes
(local app configuration)
- log4j.jar in /tomcat/lib and log4f.properties in /tomcat/classes
(global app configuration)
The situation that won't work is log4j.jar in /tomcat/lib and the
properties
file in a web app's WEB-INF/classes. In that situation a servlet such as
you
describe would be useful and, in fact, the only option.
