Impossible de lancer l'application Java JNLP après le téléchargement

Je voudrais inclure mon application java que je l'enregistre en tant que fichier jar dans le navigateur Web. J'ai essayé le tutoriel Java Web Start et créé l'application Java JNLP. Je suis également des tutoriels basés sur ici: http://transvar.org/6112/WebStartAppInstruction.pdf

J'ai essayé toutes les étapes mais après avoir téléchargé le lancement.jnlp et essayer de le lancer erreur telle" Impossible de lancer l'application " pop up. J'ai cliqué sur le bouton Détails pour vérifier où ai-je mal fait.

Voici l'erreur (onglet Exception): 

com.sun.deploy.net.FailedDownloadException: Unable to load resource: file:/C:/Users/nurulazila/Documents/NetBeansProjects/fyp_steganalysis/dist/$$codebase/launch.jnlp

Mon code (Lancement.jnlp): 

    <?xml version="1.0" encoding="UTF-8" standalone="no"?>

    <application-desc main-class="steganalysisUI">

        <script>
            deployJava.createWebStartLaunchButton("launch.jnlp")
        </script>
        <!-- Or use the following link element to launch with the application -->
        <!--
        <a href="launch.jnlp">Launch the application</a>
        -->
    </body>
</html>

Je suis vraiment nouveau dans Java JNLP. En espérant obtenir de l'aide.

Selon le document lié, Vous devez le modifier pour localiser la base de code de votre application.c'est-à-dire

<jnlp codebase="http://webpages.uncc.edu/~acenglis" href="launch.jnlp"/>

Je ne vois pas que vous avez suivi complètement le tutoriel (en particulier l'édition de votre fichier jnlp)
