Protege-OWL: java.lang.NoClassDefFoundError

Im trying to run code use protege-owl. So I added the protege.jar and protege-owl.jar to library to import edu.stanford.smi.protegex.owl.* and edu.stanford.smi.protege.*.

I also added jena jar files to use in next steps.

First i wrote simple code to see how it works :

 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());   
       }
}

But it gives me this error :

What can I do ?

Update: I replace protege.jar with protege-3.5.jar and now it gives :

Where is the problem?

Solution

  • I downloaded protege-owl.jar which is 3.24MB from different link and now it works.
