[kepler-users] Newbie with a couple of Questions

[Christopher Brooks]

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.
