Iterating multiple reasoned literals from the same property - jena

Question

The title may be a bit confusing but basically this is the problem: I am using Jena and a Pellet reasoner to produce property literals from a resource called Patient_Doug. The triple looks like this:
Patient_Doug-> hasSuggestion-> Literal inferred suggestion.
The problem is that the Protege Pellet reasoner comes up with three suggestions for Doug, because Doug is in a pretty bad way in hospital. The Protege reasoner suggests that Doug needs a Hi-Lo bed, an RF ID band and a bed closer to the nurse's station. Unfortunatly, in Jena, I can only get Hi-lo bed to print. Only one of 3 literals.
Here is some of the code.
OntModel model = ModelFactory.createOntologyModel( PelletReasonerFactory.THE_SPEC );
String ns = "http://altervista.org/owl/unit.owl#";
String inputFile = "c:\\jena\\acuity.owl";
InputStream in = FileManager.get().open(inputFile);
if (in == null) {
throw new IllegalArgumentException("File: " + inputFile + " not found");
}
model.read(in,"");
model.prepare();
//inf and reasoner wont run unless i use hp libraries!
//asserted data properties
Individual ind = model.getIndividual(ns+"Patient_Doug");
OntProperty abcValue = model.getOntProperty("http://example.org/hasABCValue");
//inferred data properties
OntProperty suggestion = model.getOntProperty(ns+"hasSuggestion");
//print asserted data properties
System.out.println("Properties for patient "+ind.getLocalName().toString());
System.out.println( abcValue.getLocalName()+"= "+ind.getPropertyValue(abcValue).asLiteral().getInt());
//print inferenced data properties
StmtIterator it = ind.listProperties(suggestion);
//this iterator only prints one suggestion in an infinite loop
while (it.hasNext()) {
System.out.println("A posible suggestion= "+ind.getPropertyValue(suggestion).asLiteral().getString());
}
}
The code works fine but the iterator at the end only prints only one subggestion in an infinite loop.
I would be grateful for any suggestions.
Thanks.

This code works to iterate and print the many inferred hasSuggestions. The hasSuggestion SWRL rules are in the OWL ontology
OntModel model = ModelFactory.createOntologyModel( PelletReasonerFactory.THE_SPEC );
String ns = "http://altervista.org/owl/unit.owl#";
String inputFile = "c:\\jena\\acuity.owl";
InputStream in = FileManager.get().open(inputFile);
if (in == null) {
throw new IllegalArgumentException("File: " + inputFile + " not found");
}
model.read(in,"");
model.prepare();
//inf and reasoner wont run unless i use hp libraries!
//asserted data properties
Individual ind = model.getIndividual(ns+"Patient_Doug");
OntProperty abcValue = model.getOntProperty("http://example.org/hasABCValue");
//inferred data properties
OntProperty suggestion = model.getOntProperty(ns+"hasSuggestion");
//print asserted data properties
System.out.println("Properties for patient "+ind.getLocalName().toString());
System.out.println( abcValue.getLocalName()+"= "+ind.getPropertyValue(abcValue).asLiteral().getInt());
for (StmtIterator j = ind.listProperties(suggestion); j.hasNext(); ) {
Statement s = j.next();
//System.out.println( " " + s.getPredicate().getLocalName() + " -> " );
System.out.println( "A possible suggestion... " + s.getLiteral().getLexicalForm());
}
