Interfacing with KDE ?

[Helge Deller]

I'm trying to help a friend to make his Java program more KDE-friendly.

In this regard, I'm interested, if there maybe is a _documented_ or _official_ 
way (DCOP would be possible) to figure out if KDE (or even GNOME?)
is currently running and then preferably a DCOP call to execute
the application associated with the filetype, e.g. something like
a DCOP-call: kdeexec("readme.txt");
I found "kfmclient exec readme.txt" to be possible, but maybe an existing
DCOP function could speed it up.

Any hints ?
