Une application web JSF essaie de récupérer des ressources à partir d'un Java EE web service. La JSF web application fonctionne très bien. Depuis que j'ai ajouté le client Http source de retrive web des ressources de service de l'instance de JBoss réclamations au sujet de:

Je suis assez sûr que le HttpClient source est très bien, puisque c'est le même qui est utilisé au service web de côté pour JUnit tests.

ProjectSetup:
Le service web est déployé sur JBoss AS7.1 (fonctionne très bien jusqu'à présent) dans Le cadre du programme client web est déployé sur la même instance de JBoss. Les deux sont lancés via Eclipse. Le Déploiement de l'assemblée de la JSF client web ressemble:

Je suppose que le lien d'erreur est provoqué par l'externe (BuildPath & DeploymentAssembly) ajouté http apache de la bibliothèque du client. Mais comment puis-je résoudre ce problème?

S'il vous plaît dites-moi si vous voulez plus de détails.
Je suis très reconnaissant pour toute aide!
