NullPointerException in Netbeans Hibernate Mapping Files e procedura guidata POJOs dal database Firebird

Question

Sto sviluppando un'applicazione desktop che utilizza netbeans, hibernate e firebird.

La procedura guidata non mi dà fastidio la creazione di file hibernate.cfg.xml, o HibernateUtil.java

ma cercando: New -> Altro -> Hibernate -> Hibernate file di mapping e POJO dal database, utilizzando il mio hibernate.cfg.xml e hibernate.reveng.xml la procedura guidata getta l'eccezione:

configurazione Hibernate fallisce con un messaggio: java.lang.NullPointerException message.log vedi eccezione per i dettagli.

sto usando

Answer 1

Una nuova domanda su questo mi ha spinto a indagare di nuovo, il problema è una combinazione di come si carica Jaybird e un programma di caricamento di classi personalizzato in Netbeans. Vedi https://stackoverflow.com/a/18920383/466862

Answer 2

eliminare hibernate.cfg.xml e hibernate.reveng.xml; E generarli nuovamente usando Netbeans. Dopo di ciò prova a creare classi di entità. Ho affrontato questo problema e questo ha funzionato per me
