 yes, but that was secondary. what i was really looking for was a way to run
 that app in the background, although it needed a console for itself.

 that was my first thaught too, as i started to experiment with that yesterday.

 that's what didn't work. it stopped the app.

 good idea. i think this will definitely work. i'll try this asap.

 the way i actually solved the problem is the following: i created a script with
 the right classpaths etc. and the full command line which should start my app.
 after trying this an that, somehow i taught, the old screen utility would
 come hany. and it did! what i can recommend to everybody out there: run your
 java startup-programs with screen -m -d -s /your/appscript. it does
automatically
 detach itself and runs in the background. very clean i must say. although this
 is a second-hand solution, it's far more easier to put in your rc-scripts and
 you can reattach to that screen whenever you want it (hmm, that should work,
 but doesn't for me).
