[jira] [Commented] (JENA-621) OntDocumentManager always resolves
policy file to ont-policy.rdf
[ https://issues.apache.org/jira/browse/JENA-621?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13867929#comment-13867929 ]
Andy Seaborne commented on JENA-621:
------------------------------------
Possible fix:
# Change the jena-core LocatorClassloader to not handle {{file:}} (it's only used by {{OntDocmentMaanger}} these days and will change sometime).
# Change the default path to {{file:ont-policy.rdf;file:etc/ont-policy.rdf;ont-policy.rdf}}
# Change tests to align.
(NB RIOT {{LocatorClassloader}} does not handle {{file:}} resources - this was possibly the original intention)

> Key: JENA-621
> URL: https://issues.apache.org/jira/browse/JENA-621
> Project: Apache Jena
> Issue Type: Bug
> Components: Ontology API
> Affects Versions: Jena 2.11.0
> Reporter: Andy Seaborne
> Priority: Minor
>
> Follows on from JENA-525.
> The {{OntDocumentManager}} has a default path for looking for policy files of {{file:ont-policy.rdf;file:etc/ont-policy.rdf}} but as of commit {{r1455078 / 2013-03-11}}, the default policy files go into src/main/resources.
> {{OntDocumentManager}} uses the old/core {{FileManager}} explicitly in {{findMetadata}} with file, URL and classloader locators.
> The core {{LocatorClassloader}} converts URIs to plain file names which then have no {{file:}} so it looks up {{ont-policy.rdf}} on the locator list. This is always found by the class loader - it's in the jar. {{file:etc/ont-policy.rdf}} will never be tried.
> The consequence is that {{file:ont-policy.rdf}} is always found - it may be a real file or in the jar.
> *Workaround*
> Set the path explicitly with {{OntDocumentManager.setMetadataSearchPath}}
