Later this afternoon, I will send you an example of how to create a rulebase from a .rules file.
I use JEOPS V2.2 from (which now uses insert instead of assert) and JDK1.4, so you might want to get these and we can synch' up and use the same stuff. They also have a proposed "wish list" for JEOPS, but I haven't seen much progress so far.
