Hi Manfred,
doesn't work here for Eden. How does it work?, there is no class-file. For Pyotr
it works (but there is a pyotr.class file). There is something I do wrong.
I used the same properties entries you showed for Eden (except the right jvm.dll
path, of course).
After starting the jlaunch exe I get the following error message: can't load
class de.czempin.chess.eden.eden
Exception raised in main method

I also tried other names for class, without success.

In the directory I have:

de.czempin.chess.eden_0.0.5.jar
eden_0.0.5.bat
jlaunch.exe
jlaunch.properties

Thanks
Axel
