I have a class, MAN. I want to add an individual, jack, with properties:

 hasage="50"
 hasadress="france"

How can I create my individual jack and add properties to him and save them into my file database.owl? Here is the connection. I use Eclipse and the Jena API.

  JenaOWLModel owlModel ;
  OntModel model;           
  owlModel = ProtegeOWL.createJenaOWLModelFromURI("file:///C:/database.owl");
  model = owlModel.getOntModel();

i am begging you to help me , it still fiew days for my thesis defence this CODE work perfectly i can save individuals in my file.owl BUT i couldnt add properties to those individuals and save them with.

please help me what should i do , i am realy worried thanks a lot in advance

     public class testins { 
static JenaOWLModel owlModel ;

public static void main(String[] args) {
OntModel model;
javax.swing.JDialog jDialog1 = new javax.swing.JDialog();

try{        
    owlModel = ProtegeOWL.createJenaOWLModelFromURI("file:///D:/file.owl");//  the link of my owl file
    model = owlModel.getOntModel(); 
    JOptionPane.showMessageDialog(jDialog1,
    "loaded with success","Information",JOptionPane.INFORMATION_MESSAGE);       
   }
catch(Exception e){
    JOptionPane.showMessageDialog(jDialog1,
            "error",
            "Information",
            JOptionPane.INFORMATION_MESSAGE);
}   


OWLNamedClass theAlert = owlModel.getOWLNamedClass("Alert"); //my class Alert
theAlert.createOWLIndividual("indivname1"); //i add here an indevidual
theAlert.createOWLIndividual("indivname2"); //i add here another indevidual

// now how to add to those two Individuals properties ?? each individual has 2
// properties , the property witch its name est_evaluer and the second est_analyser those 
// to properties will contain values so here is my problem how to add those values to an
// individual and save all of them


       Collection errors ;
       String fileName ;           
       fileName= ("D:/file.owl");
       errors = new ArrayList();

//here i'll save it and it work ,it mean that i find in my file "file.owl" 
//individuals i added witch are "indivname1" and "indivname2" in my class ALERT 
// so now my problem is how to add properties to those indiviuals i add , and save them also

    try{  owlModel.save(new File(fileName).toURI(), FileUtils.langXMLAbbrev, errors);
    System.out.println("File saved with " + errors.size() + " errors.");

  }
  catch(Exception e){         
  }

   }

}

You didn't say what the namespace you are using is. So I'm going to assume http://example.org/example#, adjust as necessary.

String NS = "http://example.org/example#";

// create ex:Man class
OntClass man = model.createClass( NS + "Man" );

// create individual ex:jack
Individual jack = model.createIndividual( NS + "jack", man );

// create some properties - probably better to use FOAF here really
DatatypeProperty age = model.createDatatypeProperty( NS + "age" );
DatatypeProperty address = model.createDatatypeProperty( NS + "address" );

jack.addProperty( age, model.createTypedLiteral( 50 ) )
    .addProperty( address, model.createLiteral( "France" ) );
