[Pellet-users] java.util.NoSuchElementException

[Christiane Telöken]

Dear Pellet users,

I am using the Jena Framework with Pellet 1.5 and would like to retrieve 
all the possible values of an objectproperty. Excecuting the following 
code causes an exception in the main method, although the specific 
objectproperty has some values.


The exception goes like:
Exception in thread "main" java.util.NoSuchElementException


The code is:

Resource prop;
ExtendedIterator exIt = ontoModel.listObjectProperties();

if (exIt != null){
   while (exIt != null){
     prop = (Resource) exIt.next();

     NodeIterator nIt = (NodeIterator) ontoModel.listObjectsOfProperty
                                       (prop, OWL.allValuesFrom);

     if (nIt != null){
       while (nIt.hasNext()){
         RDFNode obj = (RDFNode) nIt.nextNode();
         System.out.println (obj.toString());
       }
     }
   }
}

I would be very grateful to get any hints why the code causes an exception.
:)

Thank you for any help in advance,

Christiane
