Hi
I’m trying to use reverse engineering in a project with spring and hibernate support, but in the process i receive the following message:

An internal error occurred during: "Generating Artifacts".
Association cl.implementa.springproject.persistencia.mapeo.Perfil.perfilUsuarios references unmapped class: cl.implementa.springproject.persistencia.mapeo.PerfilUsuario

That’s the instalation details:

The mapping table is so simple, exists 2 tables, “profile” and “user” and i want a “many to many” relationship between the tables, so i put a “userProfile” table with theirs respectives foreign keys. When i use rev. engineering in the tables, the error ocurrs, but if i delete the “userProfile” table and only work with the others, do the process correctly.
By the way, i use postgresql-8.3.7-1 and postgresql-8.3-604.jdbc3.jar
Any help will be useful. Thanks

Also i found another problem
I don’t know if is related with the later, but in any case…
I deleted all the foreign keys in the tables to view how reach the rev. eng.
Now, the problem is that not all the tables were mapped. Of 27 tables only 11 were mapped. I tried to found some pattern in the mapped tables, but i don’t had a single clue.

I think that this would be related with the previous error message:

An internal error occurred during: "Generating Artifacts".
Association cl.implementa.springproject.persistencia.mapeo.Perfil.perfilUsuarios references unmapped class: cl.implementa.springproject.persistencia.mapeo.PerfilUsuario 

because the “perfil” and “usuario” table was mapped but the “perfilUsuario” wasn’t next to delete all the foreign keys.
I’ll wait any comments. Thanks

Well… i tried another thing
I put foreign keys in the created tables and the mapping was correctly done.
Now the question is why in some tables the rev. eng. works and in others not.
I viewed this same problem in another posts about the same topic (references unmapped class) but seems not be the same problem as mine.
Thanks in advance

terinchu,
I could not replicate this issue with many to many relationship. can you send your database schema or the table structure so that i can try to reproduce from my end
i would also recommend you to cross post to hibernate forums.

Hi
Look that backup files:
http://rapidshare.com/files/229988874/db-withoutFK.backup.html
http://rapidshare.com/files/229989804/db-withFK.backup.html

The first backup has 3 tables “user”, “profile” and a 3rd table with the “many to many” relationship, but without the foreign keys defined yet.
To apply the rev.eng. in these tables, just “user” and “profile” were mapped.

Next, in the second backup, the foreign keys were defined, then now when i apply the rev.eng., throws the “Association references unmapped class” exception.

Anyway, i finished the mapping manually, but could be helpful know the reason of all that.
Greetings.
