使用hibernate时出现Drools错误

我有一个drools项目，我必须连接到hibernate，这意味着我需要使用hibernate从数据库中读取事实 当我运行项目时，出现以下错误：

what does that mean ? could anyone tell me how can I fix that ? 
thank you 

the .drl code is : 

    package metier.environnements

    import metier.taches.ActiviteProfessionnelle;
    import metier.taches.Utilisateur;



    rule "Réseaux_disponibles"  // donne les réseaux disponibles dans la localisation de l'utilisateur
    ruleflow-group "networks"
        when
          reseau :  Reseau (reseau.getCle == "mot")
        then
            System.out.println ("Réseaux disponibles");

    end

至于加载知识库的主文件：

package metier;


import java.util.Iterator;
import java.util.List;

import metier.environnements.Reseau;

import org.drools.KnowledgeBase;
import org.drools.KnowledgeBaseFactory;
import org.drools.builder.KnowledgeBuilder;
import org.drools.builder.KnowledgeBuilderError;
import org.drools.builder.KnowledgeBuilderErrors;
import org.drools.builder.KnowledgeBuilderFactory;
import org.drools.builder.ResourceType;
import org.drools.io.ResourceFactory;
import org.drools.runtime.StatefulKnowledgeSession;
import org.hibernate.Query;
import org.hibernate.Session;

import util.HibernateUtil;



/* This is a sample class to launch a rule. */

public class testingRules {
   public static final void main(String[] args) {
      try {
          Session session = HibernateUtil.getSessionFactory().getCurrentSession();
          session.beginTransaction();
         // load up the knowledge base
         KnowledgeBase kbase = readKnowledgeBase();
         StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();



         Query query=session.createQuery("from Reseau");
        List l =query.list();
        Iterator reseaux = query .iterate();

        while (reseaux.hasNext()) {

            Reseau reseau = (Reseau) reseaux.next();
            ksession.insert(reseau);

        }

         ksession.fireAllRules();



      } catch (Throwable t) {
         t.printStackTrace();
      }
   }

   private static KnowledgeBase readKnowledgeBase() throws Exception {

      KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();

      kbuilder.add(ResourceFactory.newClassPathResource("Reseau.drl"), ResourceType.DSLR);

      KnowledgeBuilderErrors errors = kbuilder.getErrors();

      if (errors.size() > 0) {
         for (KnowledgeBuilderError error: errors) {
            System.err.println(error);
         }
         throw new IllegalArgumentException("Could not parse knowledge.");
      }

      KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
      kbase.addKnowledgePackages(kbuilder.getKnowledgePackages());

      return kbase;
   }
}

根据您提供的stacktrace，创建知识库时会发生异常。你能分享一下你在知识库中使用的规则吗？谢谢你的回答，它现在可以使用帖子中提供的规则工作了，我使用了getter$reseau.getCle==mot，我把代码放在一个新项目中，它工作了，同样的代码在其他项目中不工作，我觉得很奇怪，但重要的是它工作了，再次感谢你
