I am trying to determine precisely what class the rules engine (kie version 6) thinks the class is that was inserted. The situation is that I am inserting objects from JRuby. 1. If I pass the object to a Java program and do reflection, the class is shown to be RubyObject (i.e., "getClass().getName". 2. I did create a rule that fires on any RubyObject that is inserted but it never fires: import org.jruby.RubyObject; rule "Find any RubyObject" dialect "mvel" when RubyObject() then System.out.println("We found a RubyObject!"); end 3. When I insert an object from JRuby that is called "Message", there is what I see: [ObjectInsertedEventImpl: getFactHandle()=[fact 0:1:529888082:529888082:1:DEFAULT:NON_TRAIT:#<Message:0x1f957352>], getObject()=#<Message:0x1f957352>, getKnowledgeRuntime()=org.drools.core.impl.StatefulKnowledgeSessionImpl@5719510f, getPropagationContext()=PhreakPropagationContext [entryPoint=EntryPoint::DEFAULT, factHandle=[fact 0:1:529888082:529888082:1:DEFAULT:NON_TRAIT:#<Message:0x1f957352>], leftTuple=null, originOffset=-1, propagationNumber=2, rule=null, type=0]] How can find out exactly what are the facts in working memory and determine the precise nature of the fact I inserted?
