Have started learning Hibernate.

1. for the following table

Student (
name PK
DOB PK
address varchar
age NUMBER
)

I use natural key, a compunding key (name and DOB). How do I specify that in my hibernate mapping file ?

2. If Table A has foreign keys referring to Table B and Table C, but I am only going to insert rows into Table A. Do I still have to specify the foreign key realtion with table B/C in my hibernate mapping file ? i.e. do I have to "mention" or "include" Table B/C information in the mapping file ?
 
It is sorta covered in the JavaRanch Style Guide.
