Complicated mapping problem

I have a complicated mapping problem:
Consider the following db schema:

I need to map this to the following beans, and unfortunately I can't change nor the bean structure neither the db schema.

So far I have tried the following mappings:

This doesn't work: "collection foreign key mapping has wrong number of columns", due to the non-declaration of the composite primary key in EOUser (which I can't declare there, because I can only have 'eoUserId' in the EOUser bean). I know the db schema is sh*t (no direct PK's, only foreign keys which form a PK), but I'd like to know if it is possible to map this with Hibernate.
Thanks in advance.

I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link:
