Andy Seaborne commented on JENA-889:
------------------------------------
I have tried 2.12.1 with success. What's the exact stacktrace you get?
A slightly modified program:
{noformat}
static { LogCtl.setCmdLogging();}
public static void main(String[] args) {
System.out.println("Jena="+Jena.VERSION) ;
System.out.println("ARQ="+ARQ.VERSION) ;
System.out.println("RIOT="+RIOT.VERSION) ;
Model m = RDFDataMgr.loadModel("location-mapping.ttl") ;
FileManager.get().getLocationMapper().processConfig(m);
Model m2 = ModelFactory.createDefaultModel() ;
FileManager.get().readModel(m2, "file:foo.n3") ;
System.out.println("DONE") ;
}
{noformat}
If "foo.ttl", exists in the current directory, I get:
{noformat}
Jena=2.12.1
ARQ=2.12.1
RIOT=2.12.1
DONE
{noformat}
with either "file:foo.ttl" or "foo.ttl".
If "foo.ttl" does not exist, I get:
{noformat}
Jena=2.12.1
ARQ=2.12.1
RIOT=2.12.1
Exception in thread "main" org.apache.jena.riot.RiotNotFoundException: Not
found: file:foo.ttl

{noformat}
which is correct.
Having "foo.ttl" for "file:foo.ttl" in location mapping changes the "Not
found" accordingly.
I do have to align the "file:foo.n3" with the location mapping file.

> I tried to use a LocationMapper configuration file as described at:
> https://jena.apache.org/documentation/notes/file-manager.html. This worked
> fine in an old Jena version. But now I upgraded to 2.12.1 it seems that I
> have to omit the file: prefix in the mapped URL.
