I think I know what your problem is. I rebuilt the current code base a while back adding some features but lost the ANT and source code when my Windoz (Vista) system crashed I rebuilt my system with Ubuntu. Anyway I found the PowerJournal.jar backup and had problems getting it to run under Linux. The solution was filling out the MANIFEST.MF file that is located in the jar. (/META-INF/MANIFEST.MF)
