Hi,

I have the mapping file below. It works with my code, it is validated ok by eclipse but when I try to use the Hibernate Tools plugin for eclipse, it failed :

I cant understand the problem, my mapping file is correct and I have put lazy attributes to all my many-to-one elements :

</hibernate-mapping>

What should I do ?
Thank you
best regards

does it work when you use them directly by hibernate ?

try to update to the latest hibernate tools and see if the issue persists...

Thank you for your answer, yes it works well when I use my mappings directly by hibernate.

I think I have the latest version of hibernate tools (alpha1).

Regards
Lilian

I’m experiencing the same problem when trying to use the latest Hibernate Tools for browsing an already existing project. (hibernate-tools-3.0alpha1.tar.gz)
When creating the SessionFactory under ‘Hibernate Configurations’ I’ll get the described MappingException.



The Hibernate mappings work fine in the existing project.
