Fejl med Hibernate
Jeg sidder og prøver at få hibernate til at virke på min maskine. Jeg har fulgt tutorialen på http://www.hibernate.org/hib_docs/v3/reference/en/html/tutorial.html og jeg har implementeret alle de klasser som står i tutorialen.Til forskel bruger jeg en Resin web server, men det skulle ikke gøre den store forskel.
Jeg får følgende fejlmeddelse (kører programmet i Eclipse)
log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment).
log4j:WARN Please initialize the log4j system properly.

Line 25 i min HibernateUtil kaster exceptionen. Programstumpen er gengivet er
try {
// Create the SessionFactory
sessionFactory = new Configuration().configure().buildSessionFactory();
} catch (Throwable ex) {
// Make sure you log the exception, as it might be swallowed
log.error("Initial SessionFactory creation failed.", ex);
throw new ExceptionInInitializerError(ex);
}
Det er inden i en static blok.
Er der nogen der har et forslag til hvad dette kan skyldes..?
