It's great you found the reasons. It's weird that you were able
to run workflows without java being in the path. One more tip,
besides information shown on console using command line,
Tools->'Check System Settings' also show some system
information. <br>

<div>That's for the tip on starting from command line. I'm
using Windows 7 and the root of the problem was that java
was not in the system path. The second problem was that R
wasn't in the system path either, but there was an error
message for that.</div>

Both workflows finish in a few seconds and display
with correct images in my tests. My tests are at Mac
version 10.6.8, Java 1.6, R 2.11.1. Can you tell us
your environment configuration? Also try starting
Kepler from console (kepler.sh or kepler.bat) and see
whether there are informative messages on your
console. Thanks.<br>
