Hi, I have a big problem. I am a beginner with Hibernate.
I am trying to map a database tables to java class with JPA Annotations.
I have a table with a composite primary key. A part of this primary key is a foreign key to another table.
I try to be more clear:
TABLE_A(
el1 int,
el2 int,
primarykey(el1, el2)
)

TABLE_B(
el1_a int,
el2_a int,
el3 int,
primarykey(el1_a,el2_a,el3),
foreignkey (el1_a, el2_a) references TABLE_A(el1,el2)
)

How do I map TABLE_B to java class with JPA annotations?
Thanks a lot.
