Hi!
That's my first question to this list.
How do I get the values of an ordered fact in a JessListener?
I would like for example to capture the warnings issued in the pumps
example and make a message out of the multislot values.

I have recently inherited a bit of code that is pretty complex. So far watch-all has not been able to help me find the problems I am tracking down. Can anyone suggest other debug methods for jess rulesets?
watch-all will tell me what rules fire, but more
Try the (view) command as explained in the users manual.
Good luck!

there are some that will work with other rulebased systems out there. Just wondered if anyone

Excellent! As usual, Ernest cuts to the heart of the matter. GIGO
means just that. :-) Dr. Albert Einstein once said something to the
effect that if you can't explain your theory to a five-year-old then
your explanation is too complicated or you don't understand it yourself.

You can certainly debug Jess under any Java debugger, but obviously
you're going to be debugging at a low level. Our friend Alan Moore was
workign on a Jess debugger at one point; not sure what happened to
that project, Alan?

Also, for simple "stop when this statement is reached" kinds of debugging, I
have resorted to creating a userfunction called, not surprisingly,

In this userfunction, I set a breakpoint in the java call() method and
anywhere it is encountered in the jess script, it stops in my java de
All java based debuggers work with java only. So that means that you can
debug the jess engine itself (obviously) but not jess script/code.
There are new features of the java jvm/debugging api's/class file format
that allow non-java languages that compile down into java to be debugged at
