How to determine what classes have been loaded from where in JBoss

Question

I seem to remember some function in the JMX console which allows you to type in a class name, and see the classloaders which loaded it, and from which resources the class was loaded from. Unfortunately, I can't seem to find this. For standalone apps, I've always used the JWhich tool to get this information.

Answer 1

I'm using JBoss 4.2.0 GA, and in the JMX console, I found my component with a type archive==. Going into this MBean shows:

MBean Java Class:   org.jboss.mx.loading.HeirarchicalLoaderRepository3

Then I just had to invoke:

displayClassInfo()

with my fully qualified class name.
