Could not instantiate Seam component:
Bonjour,
Mon problème est relativement simple. J'ai créer sous Eclipse à l'aide de Jboss tools un nouveau "Seam Web project" J'ai ensuite ajouter une nouvelle "seam form" et je souhaite créer un bean Stateful avec un méthode @Factory
Cependant impossible d'afficher la page, lorsque j'enlève l'annotation @Stateful de la classe, la page s'affiche alors correctement.
Voici mon EJB :

@Stateful
@Name("Call")
@Scope(ScopeType.SESSION)
public class Call implements Serializable, CallInterface
{
/**

private static final long serialVersionUID = 177777L;
@Logger private Log log;
@In
FacesMessages facesMessages;
@DataModel
private List<String> listCalls ;
@DataModelSelection
private String s ;
@Factory(value = "listCalls")
public void fetchInventory()
{
System.out.println("Factor") ;
}
public void call()
{
}
@Remove
@Destroy
public void destroy() {
}
public List<String> getListCalls() {
return listCalls;
}
public void setListCalls(List<String> listCalls) {
this.listCalls = listCalls;
}
} |
