"[EMAIL PROTECTED]" wrote : does it change anything if you restart eclipse ? I restarted Eclipse, and it worked the first time I tried to open the SessionFactory. Then, I ran a HQL query, and it threw an error, complaining that the table didn't exist. So I edited the hibernate.cfg.xml file, correcting the database URL, and next time I tried to open the SessionFactory, I got: net.sf.cglib.core.CodeGenerationException:
