Fuzzy logic and JESS

In browsing around the net I discovered that there is a Fuzzy Logic toolkit described here that can be used with JESS (FuzzyJess!)
I wonder if Ernest could comment on the kind of problems that people use this combination to work on.

Hi Bill,
Thanks for asking! The FuzzyJess toolkit is quite a popular extension, and Bob Orchard, the developer, is an all-around great guy. We work closely to ensure that current versions of Jess and Bob's FuzzyJ toolkit work together well.
FuzzyJess makes a great environment for doing soft real-time control. In "Jess in Action" (paper copies of which I understand are finally appearing in the wild) I describe a system that controls the HVAC (Heating, Ventilation and Air Conditioning) systems for an office building. First I build it using Jess without fuzzy extensions, and then we (Bob was the co-author for this section) go back and retrofit FuzzyJess. The non-fuzzy system can control the temperature of every floor of a hundred-story building to within +/- 1 degree or so. The FuzzyJess version (with slightly enhanced "virtual hardware") keeps temperatures constant to something like 0.2 degrees.

Can we write FuzzyJess code as an OSGI bundle? I tired to write as OSGI bundle after putting the Fuzzyj110a.jar file in my project but could not able to install bundle. It says nrc.fuzzy. package not found.

Can anyone clarify me?

Thanks in advance
