Is the java file in a the correct package? This took me a
while to get but you specify in the TR.prop's file the place
where your modules are (a package name) and then under that
pacakge you need to have 'screens' package, and the HelloWorld
screen needs to be there. Otherwise the Turbine servlet never
finds it.
Hope I am correct, I've been lurking now for a few weeks, and
figure it's time to start trying to answer some of these questions.

The velocity log file (extract reproduced below) states '$hello is not a
valid reference'. Why ?
Thanks
