Hi Everyone,
I am experiencing a strange probleme while configuring/testing Hibernate+Spring+JPA+Toplink
I am making this run on a Tomcat 5.5 server.
I am using the latest versions af all these frameworks.
I get a ClassCastException when casting the first element from my result list.
java.lang.ClassCastException: fr.b2i.vizada.soapServices.dataAccess.beans.Carte cannot be cast to fr.b2i.vizada.soapServices.dataAccess.beans.Carte
That's odd!
Help would be greatly appreciate!
My Spring configuration file :

List list = entityManager.createQuery("Select object(p) FROM Carte p WHERE p.numcard='927451396149'").getResultList();
System.out.println("count : "+list.size()); //This prints "count : 1"
