Hallo zusammen,

habe ein Problem mit Hibernate. Es sollte ein Child gespeichtert werden und ich bekomme eine Fehlermeldung. Diese Fehlermeldung wurde zwar schon paar mal gepostet, aber bei den meisten gab es kein Antwort.

Vielleicht hat ja jetzt schon jemand Erfahrung damit... Bin für jeden Tipp dankbar

Hibernate version:
hibernate3.jar
