Claude,
IRIResolver.resolveFileURL() works on filenames only and
"jar:file://[jarPath]![enclosedFile]" isn't a filename.
But as a filename "jar:file:" is legal, albeit rather wierd (so for that
matter is "http:" -- try it) and so it looks like "./jar:file:/".
So IRIResolver.resolveFileURL() isn't the right function to call. You
want the non-existent IRIResolver.resolveJarURL() as access to some
implementation for jarfiles.
The general IRIResolver.resolveString returns
"jar:file://[jarPath]![enclosedFile]" because there is no code to handle
the "jar:" URI scheme (or that that URI is already correct).
The deep change is to add to the jena-iri codebase. Statics on
IRIResolver only work on the global resolver.
What is the correct absolute URI for
"jar:file://[jarPath]![enclosedFile]"
or rather, what do you want it to be?

the method getFileName("modelReading/based.n3") returns a
jar:file://[jarPath]![enclosedFile] url. I have registered a new Locator
(LocatorJarURL) using StreamManager.get().addLocator( new LocatorJarURL()
);
LocatorJarURL does as you would expect and extracts the stream from the jar.
The problem is that the IRIResolver.resolveFileURL() does not recognize the
jar: URL and converts it to
file://[directory]/jar:file://[jarPath]![enclosedFile]
While I could patch
IRIResolver.resolveFileURL() to handle the jar based URL I think this
points to a larger problem wherein file locators added to the StreamManager
do not add capabilities to the IRIResolver.
Is there a recommended way to register file based scheme (like jar) with
the IRIResolver? I am more than happy to code it if we have a
recommendation.
