Andy Seaborne updated JENA-1037:
--------------------------------
Description:
I'm trying to create a simple interface/impl that will generate Prov-O RDF and
place it on a JMS queue. This object will live in an OSGi environment and be
injected into various operating services working in a workflow. I call the
following piece of code:
{noformat}
public static OntModel createModel(final String ontologyUri) {
final OntModel model =
ModelFactory.createOntologyModel(OntModelSpec.OWL_MEM);
model.read(ontologyUri);
return model;
}
{noformat}
with the ontologyUri="http://www.w3.org/ns/prov-o";; but when it gets to the
ModelFactory.createOntologyModel(...) it chokes with the following stack trace.
{noformat}
