Hi,

I think you’re right about the class loader case being a bit of a reach. The 
jar use case is not currently critical to our usage.

The test app 

 is itself simple but the pom.xml may be a bit gnarly.


Code may be simple ("/Users/chris/" !!) but a complete, minimal example 
needs data.


Do you have standalone example? (I don't use Ont models so I'm in the 
dark about the details)

It’s 3.15, also 3.14.

I think what is happening is that reading imports from an indirected aren't 
going to know it was indirected.

Up to 3.15.0 this code had not changed in a long time IIRC so it is a different 
issue to thread about location-mapping.

or
 OntDocumentManager odm = new

all works as expected. The relative urls are retrieved using the path to the

 xmlns:base =""
in the policy file.
However, trying

the app.jar:
 java -jar /path/to/where/to/find/app.jar
I figure I'm missing some config or a uri scheme or something like that. I'm 
currently using 3.15.
Thank you for your help,

OntDocumentManager and LocatorClassLoader

Hi,

I've got a problem with OntDocumentManager when fetching resources from an 
element of the classpath via relative urls like.

When I use:

OntDocumentManager odm = new 
OntDocumentManager("https://x/a/b/c/ont-policy.rdf;)

all works as expected. The relative urls are retrieved using the path to the 
ont-policy.rdf either file or url. Part of making this work is

finds the policy resource via the LocatorClassLoader - seen with TRACE enabled

the app.jar:
