New to annotations, and I am interested in creating foreign keys, both individual and composite. Went through the documentation and found relevant material 2.2.5.1. One-to-one, and 2.2.6. Mapping composite primary and foreign keys, but found the implementation unclear. For example in the example below the relation is made using @joincolumn in one table and @onetoone in another, but then how does one table find the related fields of the other table, what else is needed for the relationshiip to be mapped correctly to a database? Are there other sources or material which either give more more complete examples or go a bit more in depth. Any assistance would be appreciated.
thanks in advance,
Illusion
