JAXB seulement poste racine de marshals/unmarshals

Question

Je suis nouveau à JAXB. Tout ce que je veux faire est, donné une chaîne de xml existante marshal, et le renvoyer dans un ejb. Le problème est que le code suivant ne semble fonctionner que pour le nœud racine, et non pour les enfants. Je voudrais que ça marche pour tout ça. Si c'est de l'aide, je n'ai pas modifié le code généré par l'alimentation dans le schéma. Tout pointeur serait utile, merci.

Answer 1

vous avalez l'exception après triage.

try { 
    root = jaxbUnmarshalFromString(xml); 
} catch (Throwable ex) { 
    // !!! Exception caught here and not rethrown 
    Logger.getLogger(NewWebServiceFromWSDL.class.getName()).log(Level.SEVERE, null, ex); 
} 
return root; // !!!root is null here 

Ma conjecture est que la racine est nulle quand vous la renvoyez. Vérifiez vos journaux car votre exception est enregistrée.

Answer 2

J'ai juste eu un problème avec le retour unmarshaller JAXB une note de racine vide. Il s'avère que je n'ai que le nœud racine vide lors de l'exécution de tests JUnit avec PowerMockito. Je me demande s'il se passe quelque chose derrière les scènes qui empêche le «vrai» démon de fonctionner.
