why you don't use file:
for example :
model.read(reader,"file:c:/pizza.owl");
yes
Do be careful that tomcat restricts access to the filesystem outside the

Hi
I am using Jena and developing a Java Web Application.
Where I need to open my existing owl file present on my pc
I wrote the code
OntModel base;
base
=com.hp.hpl.jena.rdf.model.ModelFactory.createOntologyModel(com.hp.hpl.jena.ontology.OntModelSpec.OWL_MEM
);
base.read( "locahost:8080/healthcare.owl");
That isn't a reference to localhost (even when spelt correctly :-)
http://localhost:8080/healthcare.owl
but it gives me this exception
