Bonjour, je souhaite utiliser l'API JAXB pour sauvegarder des données semi-statiques de mon application (elles seront rarement modifiées).
Voici un premier jet de mon XML Schema représentant un modèle simplifié de mes données:

Le problème se situe au niveau de l'enumeration countryType. Voici le code généré par xjc:

UK,

public String value() {
return name();

public static CountryType fromValue(String v) {

Dans mon programme principal, la toute première instruction ne s'exécute pas:
JAXBContext jc = JAXBContext.newInstance("testjaxb"); //testjaxb est le nom du package contenant toutes mes sources

Je ne trouve pas la solution qui me permet d'utiliser les énumérations XML Schema, pourtant des exemples trouvés sur le net et exactement similaires sont dits fonctionnels.
J'utilise l'IDE Netbeans. Est-il possible que celui-crée un problème? Je précise que si je modifie le schéma pour ne pas y inclure d'enumeration, le programme s'exécute sans erreur, unmarshalling puis marshalling.
Merci d'avance pour toute aide que vous pourriez m'offrir.
