Hello, I just had the "Could not find stateful Bean" error in my application. After searching in the forum, I finally understand that a bean with a wider scope (Session) kept a reference of the stateful bean that cannot be find by other sessions. Here is some snipplets of my code: The session-scoped bean | @Scope(ScopeType.SESSION) | @Name("gestionaffichage") | public class GestionAffichageBean implements GestionAffichage | The stateful bean | @Stateful | @Scope(ScopeType.CONVERSATION) | @Name("activitesByCollaborateurCrossData") | public class activitesByCollaborateurCrossDataBean implements activitesByCollaborateurCrossData | | | bla bla bla ... | | | @In | public GestionAffichage gestionaffichage; | | | yada yada ... | | | public void setRealise() | { | this.realise = true; | this.debut(); | gestionaffichage.afficherMenuActiviteParCollaborateur(); | } | Since I add the "gestionaffichage" calls in my stateful bean, "Could not find stateful Bean" errors appeared. I temporary moved the scope of "gestionaffichage" to APPLICATION to avoid problems but it's not supposed to be shared between clients. My question is: why does this error happen ? I mean, I don't have a reference of my stateful bean in my session-scoped bean; I have the exact opposite: an injection of my session-scoped bean in the conversation. So I don't get how the error is supposed to happen. Can't I inject a "wider" scoped bean in my conversation ? I certainly missed something here but I don't know what ...
