我试图运行代码使用protege-owl。因此，我将protege.jar和protege-owl.jar添加到库中以导入edu.stanford.smi.protegex.owl.*和edu.stanford.smi.protege.*。
我还添加了耶拿jar文件，以用于下一步。
首先，我编写了简单的代码以查看其工作原理：
import java.lang.Object;
import edu.stanford.smi.protege.*;
import edu.stanford.smi.protegex.owl.*;
import edu.stanford.smi.protegex.owl.jena.JenaOWLModel;
import edu.stanford.smi.protegex.owl.model.OWLNamedClass;
public class Main {
public static void main(String[] args) {
// TODO code application logic here
JenaOWLModel model=ProtegeOWL.createJenaOWLModel();
OWLNamedClass c= model.createOWLNamedClass("A");
System.out.print(c.getName());
}
}
但这给了我这个错误：

我能做什么 ？
更新：
我将protege.jar替换为protege-3.5.jar，现在它给出了：

问题出在哪里？
最佳答案
我从其他链接下载了3.24MB的protege-owl.jar，现在可以使用了。
