Fehler bei der Verwendung von Pellet Reasoner mit Fuseki Server

Question

Ich versuche den Fuseki Server mit Pellet Reasoner und Jena zu starten. Ich fand another thread, die ähnliche Problem hatte, jedoch (1) meine Fehlermeldung ist anders, und (2) es sieht aus wie die endgültige Lösung wurde nicht im referenzierten Thread zur Verfügung gestellt.

Das Problem ist, dass Fuseki sagt

no reasoner called file:///home/gosper/Desktop/tools/jena-fuseki1-1.3.1/org.mindswap.pellet.jena.PelletReasonerFactory 

Es ist nicht klar, warum es zu dieser Wurzel Punkte, wo ich offensichtlich als org.mindswap.pellet.jena.PelletReasonerFactory genannt keine Datei haben.

Dies ist meine config.ttl Datei und ich beginne Fuseki Server wie folgt:

./fuseki-server --update --config=config.ttl

ich alle notwendigen Jena Bibliotheken von here heruntergeladen und hinzugefügt, um sie zu Fuseki Wurzelverzeichnis wie beschrieben here. Schließlich meine modifizierte Fuseki-Server-Skript sieht wie folgt aus:

Answer 1

ja:reasoner 
     [ ja:reasonerClass 
     "org.mindswap.pellet.jena.PelletReasonerFactory";] 

die zu Ihrem Assembler unterscheidet.

(dieses Beispiel ist in der ersten Verbindung, die Sie geben)
