No, I don't think it is hard to understand but I added a comment to
jboss.jcml to mention that the order is important (even it is an XML
file).
BTW I had a look at the Shutdown MBean and couldn't figure out how
you shutdown the MBean (you stop and destroy the ServiceControl MBean
but there is nothing happens in the ServiceControl).

What is then the ServiceControl do compared to the DependencyManager?
Do you want to add depedency description into jboss.jcml?

To make the DM a MBean is not a biggy but to make it working right at
runtime is a little bit more difficult (normally the dependent services
should be stopped and destroyed beforehand etc.).

I would like to create a DM which not only works for jBoss (<iiiieee
change="JBoss"/>)
but for other projects.
Thanx for your time - Andy
