> I'm generating *POJO* from *Derby 10.14.2.0* database in *NetBeans IDE 11.3*,
> *Hibernate ORM 5.4.31*.
> It does not generate any {{relationship-mappings}} in {{hbm.xml}} or in
> entity classes like {{many-to-one/one-to-one}}).
> I've used two tables from Derby sample database.
> Product and PurchaseOrder
> Product table is referenced in PurchaseOrder.
> Table {{PurchaseOrder}} has {{FOREIGN_KEY_PRODUCT_ID.}}

> In above *{{PurchaseOrder.hbm.xml}}* file, {{relationship mapping}} should be

> *Expecting*
> Wizard should generate mapping relationship like many-to-one/one-to-one) in
> *{{PurchaseOrder.hbm.xml}}*
> But why {{relationship mapping}} doesn't generating?
> *With MySQL it is working fine.*
> Doesn't Hibernate support Derby properly?
> What is solution?
