Hi,
I think that if the machine where you are building is not connected to
Internet, you need to add a local version of the schema to the
OntDocumentManager. That will help you to work offline (and avoid your
application depend on an external schema).
http://jena.apache.org/documentation/ontology/#controlling-imports-processing
I can tell this because of the unknown host error you are getting.
Let me know if it worked.
Regards
Luis
PS: I think you need to address your question to the other list, this has
been deprecated.
