Create Entinity from Database -> Doesn't create any file

[Meldanor]

Hi guys,

I wanted to learn something about Persistence and used in NetBeans 6.7.1 the wizard, to create Entinity classes from a existing database.
Now I use NetBeans 6.8 and yesterday I used the wizard again to create the classes.
I've clicked finish , but nothing happened. No class was created or file. The persistence.xml existens and isn't empty. I tried it with other databases and created new projects, but the result is always the same.
I use Hibernate for this.
I reinstalled NetBeans twice, but nothing changed.

Is it a bug?
