Il semblerait que ce soit un problème au niveau du pool de connexion qui n'arrive pas à se connecter à ta BD.
Essaye déjà sans passer par un pool, vire les lignes :
hibernate.c3p0....

[kamaldev]

ça marche mnt,
avec le pool de connexion et tout
le probleme c que ttes les modifs apporté à persistence.xma ont
eu aucun impact!! parceque ce dernier n pas été signalé ds le
classpath..
voilà
