Aucun corps de message n'a été trouvé dans la classe com.sun.jersey.core.header.FormDataContentDisposition

Question

J'ai créé un service de repos pour télécharger le fichier. J'utilise le reste facile pour le téléchargement de fichiers. Aussi pour mentionner j'ai essayé toutes les solutions que j'ai trouvées sur SO pour les questions connexes. Mais ça ne marche pas pour moi. Voici ma définition de point de terminaison.

@POST 
@Consumes(MediaType.MULTIPART_FORM_DATA) 
@Path("/ckeditorUpload") 
public String uploadCkEditorFile(@FormDataParam("file") InputStream uploadedInputStream, 
@FormDataParam("file") FormDataContentDisposition fileMetaData); 

Ci-dessous le reste dans ma dépendance facile pom.xml

  <!-- JAXB provider --> 
    <dependency> 
     <groupId>org.jboss.resteasy</groupId> 
     <artifactId>resteasy-jaxb-provider</artifactId> 
     <version>2.3.1.GA</version> 
    </dependency> 
    <!-- Multipart support --> 
    <dependency> 
     <groupId>org.jboss.resteasy</groupId> 
     <artifactId>resteasy-multipart-provider</artifactId> 
     <version>2.3.1.GA</version> 
    </dependency>  
</dependencies> 

Voici l'erreur quand j'invoque ce point de terminaison.
