Hi,
I think the eventual solution will be to have it possible to deploy mbeans
in an application, loaded with the application's classloader. Hopefully
this is coming soon with marc's .jsr or .sar's for rabbithole.
Meanwhile...
1. I think you just need the interfaces in lib/ext. While unpleasant,
wrong, and a big pain, its not quite as bad as needing the beans too.
2. If you would like to experiment, you could try writing a ejb that gets
the mbean server and creates your mbean using the apps classloader. This
won't really help you out now, you'd still have to find a way to call this
ejb, but it would show that the "deploying mbeans as part of an
application" will work. If you do this please let me know.
Maybe there's an easier way? Probably using reflection on the interface
from jndi would work too.
