Hello
By some reason the workaround below does not work for
OntModel model1 = ModelFactory.createOntologyModel(
OntModelSpec.RDFS_MEM_RDFS_INF);
But works for
Model model = ModelFactory.createDefaultModel();
Do you know what the reason could be? I saw that the fix was done, but do you
know when Maven will be updated?
Ontologies have an imports manager and most of the point of the location
mapper is for ontology imports. I guess the init code touched the
locationmapper in a way the plain model does not.
The project releases every 3 or 4 months.
You can build directly from the source (we operate a "green master" -
master builds all the time, unless the project decides on a temporary
exception, which it hasn't for as long as I can remember) or use a
nightly snapshot build (which is not a formal release).

Hello Andy, all,
Adding -DLocationMap=
In the "Edit custom VM options" in Intelij didn't help. I was actually not sure
if this is the right place
However I was trying some other things and I found a good post here:
https://www.oipapio.com/question-8593703
So adding
import org.apache.jena.util.LocationMapper;
and calling LocationMapper.setGlobalLocationMapper(new LocationMapper());
did the trick.
Perhaps https://issues.apache.org/jira/browse/JENA-1775 could be updated
Best regards

file:location-mapping.rdf is a Jena system file.
It's also an area of the code that has not changed for quite some time.
I notice this is running Java13 on Windows.
The project does run the core test suite on Java13 although on Linux.
I would not be surprised if the rules for naming are tighten up in Java13. The
error is from the Windows specific JRE code.
From looking at the code:
Setting the default places to look for the lcoation mapping file is controlled by system property
"DLocationMap" (or "http://jena.hpl.hp.com/2004/08/LocationMap";).
This might work: setting the java system property to the empty string.
-DLocationMap=
(or anything legal and not existing).
sorry - I'm not in a position to recreate the setup just at the moment ... no
Windows machine setup.
If it works, please let us know.
Andy

Seeing the whole stacktrace would be helpful

Hello
Thanks. I tried and I am getting the same problem In fact my file is
stored here: C:\Users\chiva\Downloads\test.rdf and the output in the
console of System.out.println(selectedFile); is
C:\Users\chiva\Downloads\test.rdf
Even if I do like this RDFDataMgr.read(model, new
FileInputStream("C:\\Users\\chiva\\Downloads\\test.rdf" ),
Lang.RDFXML);
I still get:

file:location-mapping.rdf is not a valid path in Java. Try Model model =
ModelFactory.createDefaultModel(); RDFDataMgr.read(model, new
FileInputStream(selectedFile), Lang.RDFXML); maybe this works. Or use the
absolute path of the file object.
Hi
I am trying to import rdf schema file (RDF/XML) but when I use this
code below I am getting the a lots of messages and I see this
java.nio.file.InvalidPathException: Illegal char <:> at index 4:
file:location-mapping.rdf
I wonder if I need some specific setup or do I need to create
location-mapping.rdf?
FileChooser filechooser = new FileChooser();
filechooser.getExtensionFilters().addAll(new
FileChooser.ExtensionFilter("RDF files", "*.rdf")); File
selectedFile = filechooser.showOpenDialog(null); if (selectedFile != null) {
System.out.println(selectedFile);
Model model =
FileManager.get().loadModel(selectedFile.toString());
In general what I would like to achieve is to be able to read rdf schema file
and also at later stage to read rdf xml instance data based on the schema.
I tried to use RDFDataMgr and RDFParser to do the read, but I am kind of hitting to
the same “java.nio.file.InvalidPathException: Illegal char <:> at index 4:
file:location-mapping.rdf” which leads me to think that I am missing something from
the basic setup. I was looking at a lot of examples, but somehow could not get
oriented so far.

Chavdar
