I had the idea that @Inheritance(strategy = InheritanceType.TABLE_PER_CLASS) would give a new table with every field from the sub classes and mother class in this table. I searched the final draft on persistence after this notation but I came up with no suitable instances found. Is this assumption of the strategy correct or (especially since this is not working) is it another way of doing this?
