There are 2 tables: order and profile
In table Order: there are 3 fields that has reference to table profile. How should I define the mapping in this situation.

I recieved a runtime error:
net.sf.hibernate.MappingException: Foreign key (ORDERTABLE [SHIPPING_PROFILE_ID_FK,BILLING_PROFILE_ID_FK,ORIGINATOR_PROFILE_ID_FK])) must have same number of columns as the referenced primary key (PROFILE [PROFILE_ID])

Here are the 2 hbm.xml files:
