Hi Henri, The basic problem is that o.a.t.u.mx.DynamicMBeanProxy.java carries dependencies, which imposes requirements on the classloader hierarchy for any class that uses it. In this case the "jmx", "parser", and "tranform" jars would need to move to lib/common where tomcat-util.jar lives. I would be in favor of sacrificing code reuse to avoid these restrictions. I think this would be a lot easier than trying to implement classloader tricks.
I think the best way of accomplishing this is to make the JMX support an add-on module with its own local copy of DynamicMBeanProxy. Then, there is no impact on classloaders and enabling is simply dropping a war file in the "modules" directory. A first pass implementation, derived from what you have done, can be found here: <http://jakarta.apache.org/~larryi/JmxSupport.war> It contains the mx4j jars, so they aren't needed in lib/container. If this approach is acceptable, I can update the jakarta-tomcat build to include it. Note: You will need the recent TrustedLoader.java update before add-ons will deploy successfully.
