Erreur lors de l'utilisation de Pelleter reasoner avec le serveur Fuseki

Question

Je tente de lancer le serveur Fuseki avec Pellet reasoner et Jena. J'ai trouvé another thread qui avait un problème similaire, cependant (1) mon message d'erreur est différent, et (2) il semble que la solution finale n'a pas été fournie dans le thread référencé.

Le problème est que Fuseki dit

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

On ne sait pas pourquoi il pointe vers cette racine, où je ne suis évidemment pas un fichier appelé org.mindswap.pellet.jena.PelletReasonerFactory.

Ceci est mon fichier config.ttl et je commence serveur Fuseki comme suit:

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

J'ai téléchargé toutes les bibliothèques nécessaires Jena de here et les avons ajoutés à Fuseki répertoire racine comme décrit here. Enfin mon script fuseki-serveur modifié se présente comme suit:

Maintenant, lorsque je tente de démarrer le serveur Fuseki, l'erreur suivante apparaît:

Answer 1

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

qui est différent de votre assembleur. (Cet exemple est dans le premier lien que vous donnez)
