Well.. if you remove that line you are not including your rules in the knowledge base :) But the problem is as suspected, a fix was not back-ported. You can either use 5.5 or wait for Mario to follow up shortly with the patched 5.4 Best Davide -- View this message in context: http://drools.469

So, this had everything to do with: kb.addKnowledgePackages(kbBuilder.getKnowledgePackages()); If I remove this line, all is fine. Fortunately, in my project I do not actually need to state specific packages (I am using a ruleflow to control the flow instead). However, this should be noted as a

Thanks for the fast response! I'll attempt to post as much as I can, splicing out any case specific info. The Java code surrounding my invocation is as follows: = //Get a list of all knowledgebase resources List kbList = config.getCompleteKBList(); //Note that this is
