Bonjour,

J'ai un probleme avec Seam, je n'arrive pas à effectuer l'injection de dépendance avec seam. Je m'explique quand je lance mon projet dans les logs j'ai ceci:

17:08:08,303 DEBUG [Component] seam component not found: user
17:08:08,303 DEBUG [Component] seam component not found: org.jboss.seam.core.user
17:08:08,303 DEBUG [Component] seam component not found: org.jboss.seam.transaction.user
17:08:08,303 DEBUG [Component] seam component not found: org.jboss.seam.framework.user
17:08:08,303 DEBUG [Component] seam component not found: org.jboss.seam.web.user
17:08:08,303 DEBUG [Component] seam component not found: org.jboss.seam.faces.user
17:08:08,303 DEBUG [Component] seam component not found: org.jboss.seam.international.user
17:08:08,304 DEBUG [Component] seam component not found: org.jboss.seam.theme.user
17:08:08,304 DEBUG [Component] seam component not found: org.jboss.seam.pageflow.user
17:08:08,304 DEBUG [Component] seam component not found: org.jboss.seam.bpm.user

"user" étant le bean que j'aimerais injecter dans ma page JSF. Et j'ai cette erreur avec toutes les EL que j'utilise dans ma page.

Mon action Identify:
