How to import/read an owl ontology created by protege in Jena

Question

I created an owl ontology in Protege (ontologyEx.owl). I also have rdf triples created by r2rml engine (file name is example.ttl). Is it possible to import/read ontologyEx.owl in Jena and do reasoning with my model that reads rdf triples (i.e. Model model = ModelFactory.createDefaultModel(); model.read( "example.ttl" );) ?

Thanks!
