Look into the drools KnowledgeAgent api (do a google you should find old discussion/blog posts about it). Alternatively if you know where your drl files live and just want to do it at startup just use the standard File methods to list all the "*.drl" files in that particular directory.

I am loading it like this as of now : private static final String[] RULES_FILES = new String[]{ "Rule1.drl"}; new RuleRunner().runStatelessRules(RULE_FILES,null,list_of_data,null); If I create new rule files, I will have to keep adding it to RULES_FILES. Is there someway I can check dynamically if there are more rule files and get it added to my rulebase??
