I don't think GF has a way of disabling an individual MDB. Isolating
it in a Jar is not necessarily a bad idea.
Take your current MDB, turn it in to a Session Bean with a Remote
Interface, then create a new MDB that simply forwards the call from
the queue.
This technique keeps the MDBs really light weight, all depends on what
kind of traffic you're moving through it. If you're not moving Java
Classes as serialized objects, the MDB is single class wrapped in a
small jar file with no dependencies. If you are moving serialized
objects, you would need to bundle those classes with each MDB. If
you're just moving XML or JSON or something like that, you don't
really need anything.
Then, you have wide array of controls to control the MDBs: Adming GUI,
asadmin command line, JMX, GF REST Admin. You get all of that "for
free" by creating these simple facades.
