Answer 1

The first parser error is the one that refers to your case.

Detailed logs:

Parser: RDFXMLParser edu.unika.aifb.rdf.api.syntax.RDFParserException: [line=18:column=72] Expecting rdf:RDF element.

Can you share the ontology being parsed? It appears to have a problem around line 18.

Answer 2

At first I save the owl file with OWL/XML format and I got that Error.

Now I changed it to save with RDF/XML .., it's work ..

Thank You all . ^_^
