how can I change the order of the classes handed to AnnotationConfiguration
by Heping Zhang
hi, I've got a NullPointerException at
org.hibernate.cfg.OneToOneSecondPass.doSecondPass when deplor my ejb3 app.
And I searched on the web and find out that changing the order of the
classes handed to AnnotationConfiguration may work around the problem. But
I don't know how to do it? could anyone give me some help? thanks!
