Hello everyone,

I want to implement the following structure: entity A, which declares InheritanceType.TABLE_PER_CLASS. Then entity B extends entity A and declares InheritanceType.SINGLE_TABLE. The reason is - I want to have a base Entity for all my entities. And I want all my children entities, like User, Product, Address, etc to be in their own table. But I also want MyProduct, HisProduct, YourProduct to be in the same table as Product.

- I can't use MappedSuperclass on entity A because then I can't have *ToMany relations to my base entity A.
- I can't declare entity A as InheritanceType.SINGLE_TABLE because then it only creates 1 table - the table for entity A.
- I can't declare entity B as InheritanceType.JOINED, because then I don't have the pk and id, and some other common fields in the same table, so that when I do a OneToMany and I specify mappedBy="PK" it doesn't find it.

What is the right approach here?

Thanks.

This above seems to be the right approach for your requirements.
