I'm not sure I understood your application totally, but the easiest way I have
found to accomplish this is to subclass the Action class.  You then create a
unique instance of your Action subclass for each desired behavior.  You would
provide arguments to your constructor to set the parameter that should be sent
to the application.  And of course your subclass would override the "execute"
method so your application gets called with the parameter.
