Hibernate table doesn't exist - database

Question

When I test my project, just 4 tables are created in the database but not the others and I do not know why. The tables notification, position, dernierePosition and user are created but not the table demande and other tables that I didn't put in this example. There are some properties that i forgot?
Thanks for your help.
Here are some files:

Answer 1

It seems that there's a problem with many-to-one and joined-subclass. It's explained in detail over on the hibernate forums; I'm not entirely clear on why it's the case, but the explanation from sdknott (on that site) is:
The problem you have is with your mapping. By stating that your constraining column of the many-to-one is in fact your primary key column of table A, Hibernate will always try and resolve an entity B since the many-to-one column will never be empty.
I've used your source and changed the various many-to-one mappings in joined-subclasses to one-to-one mappings, and it all works for me now. Hopefully that will allow you to express your schema correctly.
(Aside) Original answer that didn't solve the problem
I see that you have two members called "user" in the Demande class; remember that Demande is a subclass of Notification and gets its members. I've never tried that and it looks odd, and it's definitely going to be confusing. It might be what's causing your problem.
If you really want two "user" members, give them more suitable names (maybe "requester" and "responder"? Just guessing from the context). If you only want one "user", then you don't need to put it in Demande, it's already in Notification.
