Il me semble que la relation bi-directionnelle entre les entities Parent et Child OneToOne - ManyToOne une fois traduit en XML dans le WSDL provoque l'erreur.

Comment procéder pour garder cette relation entre les entities et utiliser le webservice ?

Merci.

Bonjour à tous,

désolée je remonte le post car il n'a y a pas eu de réponses au problème et je me retrouve exactement dans le même cas de figure.
Je ne veux pas utiliser l'annotation @XMLElement qui engendre la perte de cette relation bidirectionnelle.

Merci à vous.
J'espère que ça ne pose pas de pb que je poste ici, si oui, veuillez m'en excuser.
