Hi Emilio,
Plain new FileManager() is going to return an FileManager object with no
handlers. FileManager.get() is the standard configured one. Could you
try that please?
What does f.getAbsolutePath() return? There may be drive letter
confusion going on.
Does
String fn =
"/Users/emiguelanez/sb.work/sb.dev/onto-db/ont-seed/target.owl" ;
RDFDataMgr.readModel(bModel, fn) ;
work?
RDFDataMgr.readModel is newer preferred style - it's using the same
machinary as FileManager.

Hello all,
I have some issues reading from a local file.
The details are as follows:
— Using latest version: apache-jena-2.10.1
— Main owl file imports local file, as follows
<owl:Ontology rdf:about="">
<owl:imports
rdf:resource="file:///Users/emiguelanez/sb.work/sb.dev/onto-db/ont-seed/target.owl"/>
</owl:Ontology
— TDB is creating using ./tdbloader2, loading main owl file
— In the application, the following code fails
Dataset ds = TDBFactory.createDataset(repoDir) ;
Model bModel = ds.getDefaultModel();
OntModel aModel = ModelFactory.createOntologyModel(spec,
bModel);
given the following exception, triggered at the creation of the OntModel
[com.hp.hpl.jena.ontology.OntDocumentManager] :: An error occurred while

— I have done two tests:
++ Test 1: run the following code
File f = new
File("/Users/emiguelanez/sb.work/sb.dev/onto-db/ont-seed/target.owl");
logger.info(f.exists()); // prints "true"
new FileManager().readModel(bModel, f.getAbsolutePath());
logger.info("Done");
and fails
++ Test 2: run the following code
File f = new
File("/Users/emiguelanez/sb.work/sb.dev/onto-db/ont-seed/target.owl");
logger.info(f.exists()); // prints "true"
bModel.read(new FileInputStream(f),"");
logger.info("Done");
and succeed.
I could include the code from the second test into the application, but I don't
want to include file directories into the code.
Any ideas what is happening?
Cheers,
Emilio
