The solution is simple ... you need to use a FuzzyRete object and not a Rete
object ...
see the user guide FuzzyJess section ...
How to use the Fuzzy Extensions with Jess
To use the extension with Jess is really quite simple. You need to have access
to the FuzzyJ Toolkit and FuzzyJess packages (nrc.fuzzy and nrc.fuzzy.jess).
These will have been obtained with the appropriate licence requirements being
met. Normally these will be in a Java jar file for easy inclusion in the
classpath variable. The only other thing that is required is that instead of
using the Rete object in programs, you must use the FuzzyRete object. For
convenience the classes nrc.fuzzy.jess.FuzzyConsole and
nrc.fuzzy.jess.FuzzyMain have been provided and they can simply replace any use
of jess.Console or jess.Main.
Consider the code for FuzzyMain:
public class FuzzyMain extends Main
{
public static void main(String[] argv)
{
FuzzyMain m = new FuzzyMain();
m.initialize(argv, new FuzzyRete());
m.execute(true);
}
}
and the code for FuzzyConsole:
public class FuzzyConsole extends Console
{
public FuzzyConsole(String name)
{
super(name, new FuzzyRete());
}
public static void main(String[] argv)
{
new FuzzyConsole("Fuzzy Jess Console").execute(argv);
}
}
To start the FuzzyConsole one might execute a command line similar to the one
to start the standard Jess Console:
java -classpath "%classpath%";f:\fuzzyjtoolkit\fuzzyj15a.jar;.\
nrc.fuzzy.jess.FuzzyConsole
with appropriate entries in the -classpath option to allow all necessary
classes to be located. If you have been able to use standard Jess then you will
no doubt have little trouble using FuzzyJess.

Subject: JESS: FuzzyJess: Example won't run
The only pure jess (no java) example utilizing fuzzy logic was the one in the
NRC-44882.pdf document, but attempting to run that example gives me no results.
No error messages, no nothing. I corrected a miner typo I have found in it, but
apart from it, I changed nothing. I checked all the warnings (I'm working in
Eclipse) and the only one that seems suspicious is: Undefined function at token
'fuzzy-match'. Is this normal behaviour? Anyone knows of the example I'm
talking about? Any successful runs?
any reply would be greatly appreciated
