OK, i mean 'application' then?
The point was it's a small function you can implement to register an api
call so you can
run a java application from the console at startup or whatever that can stay
active in it's own thread
and spawn calls, listen on the web, whatever.
such as

Yes, swig is not pretty.

That would be a useful feature, if you are up to it, we will do our best to
