Erreur "Target Unreachable, identifier 'helloWorld' resolved to null"
Bonjour,
J'ai une erreur toute conne dans mon appli (sous tomcat 6) mais je suis tellement dans les nuages que je ne trouve pas seul. Quelqu'un peut-il m'aider ?
En gros, je travaille sur un POC de Seam 3. Je build mon projet avec Maven 3.
Mon projet est composé de 2 modules : seampoc-web et seampoc-domain.
Le pom de seampoc-web :

J'appelle HelloWorld depuis un xhtml qui est un simple copié collé de celui généré par l'archetype.
Mais j'obtiens l'erreur suivante :

Par contre, quand je met HelloWorld dans le module seampoc-web (dans le package com.icauda.seampoc.domain), là ça marche...
J'ai dû oublier un truc vraiment tout con. Donc si quelqu'un a une idée...
Évidement c'est seampoc-web qui contient le web.xml :
