Hi Kaushik, It looks like you are running Kepler-1.0.0 under Linux or Mac OS.
The issue is that the Display actor is a gui actor, so running -nogui causes problems. Try ./kepler.sh -runwf HelloWorld.xml To write to stdout, try using a LineWriter or ExpressionWriter actor. _Christopher Kaushik Vinjamuri wrote: > Hey guys, > > I just got introduced to the kepler project and wanted to get started right > away but I ran into a few problems, maybe someone here can tell me what i'm > missing.
