Comment faire cela fonctionne intégré

Question

Je combine jax-rs HelloWorld example et building executable jar

Mon attente est de créer ce monde avec toutes les dépendances bonjour à l'intérieur d'un fichier JAR.

Après extraction du paquet heroku-je ajouter ceci au pom.xml (comme décrit dans la deuxième discussion + modifier classe principale juste Main):

<plugin> 
    <groupId>org.apache.maven.plugins</groupId> 
    <artifactId>maven-jar-plugin</artifactId> 
    <version>2.2</version> 
    </plugin> 
    <plugin> 
    <groupId>org.apache.maven.plugins</groupId> 
    <artifactId>maven-assembly-plugin</artifactId> 
    <version>2.2-beta-4</version> 
    <configuration> 
     <descriptorRefs> 
     <descriptorRef>jar-with-dependencies</descriptorRef> 
     </descriptorRefs> 
     <archive> 
     <manifest> 
      <mainClass>Main</mainClass> 
     </manifest> 
     </archive> 
    </configuration> 
    <executions> 
     <execution> 
     <phase>package</phase> 
     <goals> 
      <goal>single</goal> 
     </goals> 
     </execution> 
    </executions> 
    </plugin> 

Après que je construis: > mvn package. J'ai mon pot au: target/jax-rs-heroku-1.0-SNAPSHOT-jar-with-dependencies.jar. J'ai placé la variable d'environnement de PORT à 8080. Je cours le pot avec:

>java -jar jax-rs-heroku-1.0-SNAPSHOT-jar-with-dependencies.jar

Jersey started with WADL available at http://localhost:8080/application.wadl. 

Jusqu'ici tout semblant parfait! Maintenant, si je visite la page:

http://localhost:8080/application.wadl 

Ici le vrai problème commence. Le navigateur me donne un Server error. Après avoir visité la page, j'ai une exception dans le journal de la console:

Qu'est-ce que je fais mal?

Pouvez-vous télécharger le prj à github ou quelque chose? il semble que vous ayez des dépendances dans le mauvais champ.
