Just on this point:
Is that path file:///home/text/tools/apache-jena-fuseki-3.9.0/webapp/ correct, should it be file:/home/text/tools/apache-jena-fuseki-3.9.0/webapp/ ?
file:/// is correct An absolute URI is scheme://authority/path (RFC3986). file:/ is what Java produces - strictly, it's not an absolute URI. Jena copes with file:/ internally. (Not that the file: URI scheme is that well defined.)
Where does that setting come from?
Jena converts file paths to file: URIs
