Ok, I tried with Tomcat 5.0.19 and 4.1.29. It works fine on 4.1.29 but it
fails on 5.0.19 (and .18) with the following error:

So, it would appear that Tomcat 5's JMX jar is overriding my web-app's JMX
jar.
Can anyone tell me how Tomcat 5 uses JMX? Is it possible to move Tomcat's
JMX jar into the server/lib directory? I understand that Tomcat can use JMX
for the management webapp, but is it required, or optional? Are there any
other reasons to use JMX? The tomcat installation will be deployed
stand-alone with only my web app and whatever comes standard with Tomcat 5
(i.e. the management web app, etc).
Thanks,
Mark

Perhaps it's worth trying with 5.0.19?
Back to your original question: there's also commons-modeler
(http://jakarta.apache.org/commons/modeler/) to consider. Tomcat uses
modeler fairly heavily to build its beans, and modeler had an MX4J
dependency last I checked.
