Bonsoir,
Etant débutant avec Hibernate, je rencontre un problème au niveau d'un fichier de mapping

Et voici ce que j'obtiens avec ant:
[java] log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment).
[java] log4j:WARN Please initialize the log4j system properly.
[java] org.hibernate.MappingException: Repeated column in mapping for entity: Bibliotheque.Document column: DOCUMENT_ID (should be mapped with insert="false" update="false")

Bien sûr je n'ai pas tout mis mais l'erreur viendrait bien du fichier de mapping document.hbm.xml
Merci d'avance pour vos réponses
