--------------------------------------------------------------
I've been playing with the jBPM5 CR1 demo and I seem to having some issues with the \
Eclipse tooling. When I import the sample project, the jBPM library does not load \
with it resulting in several compilation errors. This leads me to my first question. \
Does the jBPM5 runtime get installed into eclipse when you run install.demo?
After I add the jBPM5 runtime manually to Eclipse and apply it to the project I get \
the following error when I run the ProcessTest program:
java.lang.NoSuchMethodError: \

Looking at my jBPM5 library all the required jars are there so it's strange that I \
would be getting this error.
