Læsning af fil, output til JFrame, output vises ikke?

Hej alle. Har lavet mit hidtil største system, but no work, prøvede at køre min klasse fileReader i et lukket test projekt i Eclipse, der fungerede det, men når jeg kobler det på resten af systemet, med JFrame, JLabels, keylistener osv så virker det ikke.

Når jeg skriver en kommando i min lille "kommandoprompt" og prøver at eksekvere kommandoen, så får jeg intet output..

Please help!
