> As described in hibernate forum (http://forum.hibernate.org/viewtopic.php=
?t=3D960763) and discussed with Emmanuel, I encounter a strange behaviour w=
ith annotations depending of my package's names.
> Supposing hibernate load classes by package alphabetical order; if it get=
 the "parent" class first all works fine, if it get the "child" class first=
, it raise an exception !=20

ated things, then followed by the exception stack :=20

> Indeed, depending on the package names I get or not an excpetion !
> It doesn't work with the package fr.ifis.entity.project but if I rename t=
he package in fr.ifis.entity.aproject and then move it "before" the field.c=
ard package, all works fine.
> In order to facilitate the identification of the problem, I also include =
as attachement the eclipse project of this problem repport.
> In order to keep reasonable the size of the attachement, I did not includ=
ed the libraries nor the configuration files for launch ejb3-embedded. Thos=
es files are issued from the project simple-deployment included in JBoss EJ=
B 3.0 RC8-FD. The only change i've done was to specify in embedded-jboss-be=
ans.xml the properties of my database.
