Thanx for your hints but you might have missunderstood something. All the classes needed from Drools plugin are found and I can initialize the ruleBase unless I try to add an import statement for a java class into the DRL file. When the DRL file gets parsed by Drools I get this strange exception. Don't know why the class cannot be found. I assume the class is loaded by means of reflections in Drools. This means when the class is on class path it should also be found or do I forget something important???
