Drools get WorkingMemory to see facts in DRL

How can I get the WorkingMemory to know about the facts written in the DRL? Currently, the facts declared in the DRL do not exist in the WorkingMemory

DRL only describes facts and rules, you have to inject facts into working memory by yourself. In RHS you can inject new facts in WM but for order rule engine to reach your RHS, it needs some objects already injected and matched against LHS.

Add this to your KnowledgeSession/WorkingMemory:

knowledgeSession.addEventListener(new DebugWorkingMemoryEventListener());
