Hi I have 2 tables (table1 & table2). Table 1 has 2 columns(table1ColA & table1ColB) which are unique. Table2 has 2 similar columns which I define as foreign keys of Table1.

So Table2 (table2ColA & table2ColB) == foreign key reference to Table1(table1ColA & table1ColB)

When I try to generate the Hibernate Mapping Files, this is the error I get

"org.hibernate.MappingException: Foreign key (FKCB773E2441174225:table2 [table2ColA,table2ColB])) must have same number of columns as the referenced primary key (table1 [id])"

Why is hibernate trying to pick table1's primary key as the referenced primary key when in mySQL the foreign key is defined as (table1ColA & table1ColB) which have unique constraint on them? How do I tell Hibernate to use the foreign key defined in mySQL as the foreign key and not assume that the primary key of the referenced table is the foreign key? Table definition can be found below. Thanks!
