Problème d'ajout fichier PDF dans alfresco

Bonjour,
J'utilise l'alfresco lab stable v3 comme ECM.
je configure le JCR dans alfresco.
La connexion au JCR est réussite.
Alors, je peux ajouter des dossiers, mais je n'arrive pas d'ajouter un fichier pdf.
Donc : j'ai un problème d'ajout d'un fichier PDF dans alfresco via JCR !



je suis entrain d'ajouter un fichier pdf dans alfresco avec JCR via un code java.

voila le code suivant :

String fileName = "AlfrescoFAQ_1_1_FR.pdf";
FileInputStream inputStream = new FileInputStream(fileName);

vJcrNode = vJcrSession.getRootNode();
Node createdNodeRef = vJcrNode.addNode(new File(fileName).getName(), "nt:folder");
createdNodeRef.addMixin("mix:referenceable");
createdNodeRef.addMixin("mix:lockable");
createdNodeRef.addMixin("mix:versionable");

Node dataNode = createdNodeRef.addNode("jcr:content", "nt:resource");
dataNode.setProperty("jcr:mimeType", "application/pdf");
dataNode.setProperty("jcr:data", inputStream);

vJcrSession.save();

Mais, je n'arrive pas d'ajouter le fichier pdf (sachant que le fichier pdf se trouve dans le même répertoire avec la classe qui contient le code au dessus)

et voila l'erreur :
