I created a debugger quite a few years back (Jess version 4.xx) that I

It didn't do exactly what you want and it was pretty crude since it was

Please provide the exact code and error messages you are getting. Please
try to figure out whether the problem is with Protege, JessTab and/or

For example, copy key portions (e.g. function names, exception names) of

Scott,
Someone else is likely to have a more relevant answer but I thought I'd
give my 2 cents worth - it's been a while (15 years?!) so I hope I can
remember this correctly...
During my graduate studies I worked with Dr. Len Myers and others at

Yuri,
You can use any/all facilities that Java has for matrices since Jess has
full (reflective) access to the Java/third-party matrix APIs - see:

If you want to pattern match against elements in a matrix, you can use
multifields or ordered facts. For
