title: How to import owl classes into the eclipse
body: <p>I want to import and list semantic web (owl) file's classes into the eclipse. I did import pellet and protege library my eclipse program but still I see force close my android project. nothing red line or wrong code because I used same codes in net beans. my codes  is below.. </p>
  
  <pre><code>public static final IRI localLocation_IRI = IRI.create("file:c:///rdfex.owl");
  public static final IRI Ont_Base_IRI = IRI.create("http://www.emkarhafriyat.com/owlex.owl");
      OWLOntologyManager m = OWLManager.createOWLOntologyManager();
      OWLDataFactory f = OWLManager.getOWLDataFactory();
      OWLOntology o = null;
      public void testAddAxioms() {
          try {
              o = m.loadOntologyFromOntologyDocument(Ont_Base_IRI);
              OWLClass clsA = f.getOWLClass(IRI.create(Ont_Base_IRI + "#ClassA"));
              OWLClass clsB = f.getOWLClass(IRI.create(Ont_Base_IRI + "#ClassB"));
              // Now create the axiom
              OWLAxiom ax1 = f.getOWLSubClassOfAxiom(clsA, clsB);
              // add the axiom to the ontology.
              AddAxiom addAxiom1 = new AddAxiom(o, ax1);
              // We now use the manager to apply the change
              m.applyChange(addAxiom1);
              // print all classes
              for (OWLClass cls : o.getClassesInSignature()) {
                 EditText edit = (EditText) findViewById(R.id.editText1);
                 edit.setText((CharSequence) cls);
              }
              m.removeOntology(o);
          } catch (Exception e) {
              EditText edit = (EditText) findViewById(R.id.editText1);
              edit.setText("Not successfull");
          }
      }

  <p>I have mistake this code segment</p>
  
  <pre><code>public static final IRI localLocation_IRI = IRI.create("file:c:///rdfex.owl");
  public static final IRI Ont_Base_IRI = IRI.create("http://www.emkarhafriyat.com/owlex.owl");
