我尝试连接到推理赛车手。但我收到连接错误。我知道有很多关于以下错误的线程。我读了大部分。但我无法解决这个问题。这是我的代码：

import com.racersystems.racer.Reasoner;
import com.racersystems.racer.ReasonerFactory;
import org.semanticweb.owlapi.apibinding.OWLManager;
import org.semanticweb.owlapi.model.OWLOntology;
import org.semanticweb.owlapi.model.OWLOntologyCreationException;
import org.semanticweb.owlapi.model.OWLOntologyManager;
import org.semanticweb.owlapi.reasoner.*;

import java.io.File;
public class Test4 {
    public static void main(String[] args) {
         File file=new File("C:\\IdeaProjects\\second\\edo.owl");
         OWLOntologyManager owlOntologyManager=  OWLManager.createOWLOntologyManager();
         OWLOntology owlOntology= null;
         try {
             owlOntology = owlOntologyManager.loadOntologyFromOntologyDocument(file);
             OWLReasoner owlreasoner=new Reasoner.ReasonerFactory().createReasoner(owlOntology);
             System.out.println(owlreasoner.isConsistent());
         } catch (OWLOntologyCreationException e) {
             e.printStackTrace();
     }         
   }
 }

但我收到以下错误：

由于以下行而生成错误：

  OWLReasoner owlreasoner=new Reasoner.ReasonerFactory().createReasoner(owlOntology);

我在 Intellij 的 lib 下有 owlapi-bin.jar 和 racer.jar。我认为必须在我的计算机上打开作为 Racer Reasoner 的服务器。因此，我在我的电脑上打开了 Racer 和 RacerPorter。非常感谢您的帮助。
