The generated SQL (show_sql=true):
This does not do queries, only creates the table structure.
Debug level Hibernate log excerpt: debug
Within the Hibernate 3.0 install there is an example in the "eg" directory. I am trying to recreate it, because hands on is better than just looking.
Anyway, whenever I try and use the "natural-id" which is used heavily in the "eg" job, it fails. Stating the DTD cannot find the natural-id, see above error message.
When I look at the 3.0 DTD it is there? Any ideas?
Also, the big question, is there any mailing list where people can talk about Hibernate, and ask questions without having to deal with all this point system. There are times when it would be nice, just to throw a question out and see what others are doing, as opposed to having to worry about using all the points up. I think this would really help the community.
