I'd recommend reading the full pathname from a configuration file.. you can provide your own or use changeset resources. A new (still unofficial) feature is coming that will help configuring knowledge bases. Otherwise, you're explicitly telling the program to go and look for that file in that path.. there's no way it can figure out that another file with the same name somewehere in your classpath/machine/universe is actually the drl you're looking for :) -- View this message in context: http://drools.46999.n3.nabble.com/Move-the-rule-file-drl-tp4020147p402015...
