Ontology Load Exception

Je suis débutante en ontologie. J'essaie de manipuler une ontologie à travers Eclipse mais je trouve des problèmes malgré que j'ai installé tous les JAR nécessaires de Protégé.
Voici mon code:

Code:

et le résultat du run est:

Exception in thread "main" java.lang.Error: Unresolved compilation problems:
The type edu.stanford.smi.protege.exception.OntologyLoadException cannot be resolved. It is indirectly referenced from required .class files The method createJenaOWLModelFromURI(String) from the type ProtegeOWL refers to the missing type OntologyLoadException at conn.Onto.main(Onto.java:26)

---

Une chose est sûre : il faudrait corriger l'URL de l'ontologie.

Code:

---

String ONTOLOGY_URL = "fille:///C:/Program_Files/Protege_3.4.7/examples/krs1.owl";

---

Mettre "file" au lieu de "fille" et probablement "Program Files" au lieu de "Program_Files".

Code:

---

Unresolved compilation problems: The type edu.stanford.smi.protege.exception.OntologyLoadException cannot be resolved

Ce message d'erreur indique qu'il manque un jar dans ton classpath. En l'occurrence il s'agit du jar "protege.jar" qui est à la racine de Protege 3.
Si tu as ensuite d'autres messages d'erreurs similaires il faudra trouver dans quel jar est la classe manquante, et les ajouter à ton classpath.

Merci pour vos réponses Sapience et April Fool.
Le problème est que j'ai ajouté tous les JAR qui existent dans le répertoire de protégé 3.4.7.(plugins).
Pouvez-vous m'aider?

Vérifie que tu as ajouté "protege.jar", qui n'est pas dans le répertoire plugins, mais à la racine du répertoire Protégé.

Merci Sapience pour votre réponse.
Ca marche mais j'ai trouvé d'autres fautes :

C'est explicite, non ? vérifie le chemin de ton fichier, voir la réponse d'April Fool précédemment.

j'ai vérifié le chemin et j'ai corrigé le chemin.

qu'est ce ça veut dire:

---

"java.lang.NullPointerException"

Merci de vos réponse

8O c'est dans le forum sur Java qu'il faudrait poser ta question...

ok, merci Sapience.

j'ai corrigé des fautes mais il reste une autre malheureusement

Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

voici le code qui pose problème

Code:

---

OWLModel owlmodel = ProtegeOWL.createJenaOWLModelFromURI(url);

merci de vos réponses

Essaie plutôt :

Code:

---

String uri = new File("C:/Program Files/Protege_3.4.7/Krs1.owl").toURI();

---

au lieu de :

Code:

---

1 2	String url = "file:/C:/Program Files/Protege_3.4.7/Krs1.owl"; url = URLEncoder.encode(url, "UTF-8");

---

Merci de votre réponse April Fool mais il y a un autre problème

Code:
