How to use relative path to reference json schema when exporting to Json?

[gustavofarias]

I have this simple report attached and would like to export it to JSON using a schema also attached.

Differently from subreports, images, etc I can't reference the json schema with a relative path. Since it is in the same folder of the report I expected to use just "schema.json" as expression to net.sf.jasperreports.export.json.schema
. If I use an absolute path like 'C:usersusernamepathtoschema.json' it works fine.

This also prevent me from using schemas in Jasper Server.
