Do your mbeans implement the jboss service lifecycle? Exactly when do they
need the ejb? If you access it in your mbean constructor, you will have to
do something like nesting packages or prefixing a number to the file names
to force the ejb's to load first. If you access the ejb in the start or
startService method you should be able to use the <depends> mechanism.
You didn't say if you are already packing everything in an .ear.
