[EJB3] problèmes annotations
Bonjour à tous,
Je suis un débutant sur les ejb et je dois faire un projet (un site qui dynamique qui permet de gérer une base de données) et pour cela j'aurai besoin de récupérer le nom des colonnes de mes tables pour faire mes formulaires. Je pensais les récupérer à l'aides des annotations contenues dans la classe de ma table mais je rencontre un problème c'est que je n'obtiens qu'une partie des annotations et malheureusement pour pas celle qui m'intéresse.
j'utilise le code suivant pour récupérer les annotations.
Code:

|
Annotation[] test =actor.getClass().getAnnotations();
for(int i=0;i<test.length;i++)
{
System.out.println(test[i].toString());
} |
Et voilà le résultat que j'obtiens.
Code:
1

| @javax.persistence.Entity(name=)
@javax.persistence.NamedQueries(value=[@javax.persistence.NamedQuery(hints=[], name=Actor.findByActorId, query=SELECT a FROM Actor a WHERE a.actorId = :actorId), @javax.persistence.NamedQuery(hints=[], name=Actor.findByFirstName, query=SELECT a FROM Actor a WHERE a.firstName = :firstName), @javax.persistence.NamedQuery(hints=[], name=Actor.findByLastName, query=SELECT a FROM Actor a WHERE a.lastName = :lastName), @javax.persistence.NamedQuery(hints=[], name=Actor.findByLastUpdate, query=SELECT a FROM Actor a WHERE a.lastUpdate = :lastUpdate)])
@javax.persistence.Table(uniqueConstraints=[], catalog=, schema=, name=actor) |
Donc voici ma class Actor qui a été généré automatiquement à partir de la table actor de ma base de donnée

Donc si quelqu'un pouvait me renseigner sur la manière que je peux utiliser pour récupérer mes annotations Column ça me serait très utile.
Merci d'avance pour votre aide
