import org.drools.agent.KnowledgeAgentFactory;
import org.drools.agent.RuleAgent;
import org.drools.definition.KnowledgePackage;
import org.drools.definition.type.FactType;
import org.drools.runtime.StatefulKnowledgeSession;

@SuppressWarnings("restriction")
public class DroolDemo {

        /**
         * @param args
         * @throws IllegalAccessException
         * @throws InstantiationException
         */
        public static void main(String[] args) throws
InstantiationException,
                        IllegalAccessException {
               
                KnowledgeAgent ruleAgent =
KnowledgeAgentFactory.newKnowledgeAgent("/Guvnor.properties");
               
               
System.out.println(ruleAgent.getKnowledgeBase().getFactType("org.sample","NumberTest"));

                KnowledgeBase ruleBase = ruleAgent.getKnowledgeBase();
               
               
System.out.println(ruleBase.getFactType("org.sample","NumberTest"));
               
                FactType factType =
ruleBase.getFactType("org.sample","NumberTest");
               
                Object obj = factType.newInstance();

                factType.set(obj, "numberone", 2);

                factType.set(obj, "numbertwo", 1);

                StatefulKnowledgeSession workingMemory =
ruleBase.newStatefulKnowledgeSession();

                workingMemory.insert(obj);

                workingMemory.fireAllRules();

                System.out.println(factType.get(obj, "message"));
