org.hibernate.MappingException: entity class not found

Hey, ich bekomm bei einem Hibernate-Projekt folgenden Fehlermeldung:

Meine hibernate.cfg.xml sieht so aus:

wie sieht denn HsagUser.hbm.xml inhaltlich genau aus?
die Fehlermeldung klingt danach, als wenn dort die Klasse nur als HsagUser angegeben ist, ohne package

Hey, genau das war es.

Leider kommt jetzt eine andere Fehlermeldung:

auch in hmb.xml referenzierte andere Klassen müssen mit vollständigen Namen angegeben werden 😉
einmal um die Ecke denken?

Ja, stimmt schon. Bei Hibernate ist man jedoch nach 2h so frustiert, weil man von einer Exception in die andere läuft, dass man den Blick verliert, woran es jetzt liegen könnte...
