Affichage d'un PDF ( blob ) depuis oracle -> Pourquoi UPDATE ?
Petit soucis avec hibernate !
J'affiche un Document ( blob oracle ) au format pdf dans IE, le tout via une action struts qui retourne un byteArray.
Tout se passe bien, le pdf s'affiche, malheureusement j'ai des soucis de perf et de lock et je m'apercois lorsque je debug hibernate qu'il y'a un update fait à chaque affichage du document. Hibernate detecte que le blob est "dirty" est donc a été modifié !!!
Quelqu'un a-t-il déjà rencontré ce problème ?? Cela peut il venir de ma conf hibernate pour le document ?? Si oui, je peux mettre la conf ici si besoin ...
Voici les logs bizarre que j'obtient :
