[Pellet-users] Problem with running the RulesExample2 sample

[Role Francois]

Hi Pellet users,

When running the following sample program :

package org.mindswap.pellet.examples;

import java.util.Iterator;

import org.mindswap.pellet.jena.PelletReasonerFactory;

import com.hp.hpl.jena.ontology.Individual;
import com.hp.hpl.jena.ontology.ObjectProperty;
import com.hp.hpl.jena.ontology.OntClass;
import com.hp.hpl.jena.ontology.OntModel;
import com.hp.hpl.jena.rdf.model.ModelFactory;
import com.hp.hpl.jena.rdf.model.Property;
import com.hp.hpl.jena.rdf.model.Resource;



public class RulesExample2 {
    public static void main(String[] args) {


        String ont = "http://localhost/dl-safe.owl";

        OntModel model = ModelFactory.createOntologyModel(
PelletReasonerFactory.THE_SPEC, null );

       model.read( ont );

                ObjectProperty sibling = model.getObjectProperty( ont +
"#sibling" );

                OntClass BadChild = model.getOntClass( ont + "#BadChild" );
                OntClass Child = model.getOntClass( ont + "#Child" );

                Individual Abel = model.getIndividual( ont + "#Abel" );
                Individual Cain = model.getIndividual( ont + "#Cain" );
                Individual Remus = model.getIndividual( ont + "#Remus" );
                Individual Romulus = model.getIndividual( ont + "#Romulus" );

                model.prepare();


        System.out.println("Hello World !!!****jjjj");
    }
}


I get the following error mesage (model.prepare() seems to cause the
program to fail) :
