As far as I know, the parser does not check the number of rules in a DRL Maybe you could do something like this: (i) use a KnowledgeBuilder to load the DRL resource; (ii) before you add the packages to the knowledgeBase, iterate over kBuilder.getKnowledgePackages() to find the package generated from your DRL; (iii) use getRules().size() on the package to check if the number of rules exceeds your desired threshold

For an even less technical solution you could have a person with a big stick standing behind the users... I think what we are all wondering is why you want to limit the number of rules!

thanks for all of the responses, fun to read :) Sorry I thought it was pretty strait forward question. I would assume somehow the parser 'knows' how many rules are in a drl file.... I do not want an over ambitious user to just create rule after rule after rule (though I suppose he could technically do a lot even in one rule)
