jpa error uses a non-entity [class ch.printsoft.mailhouse.usermgr.entity.Department] as target entity in the relationship attribute

Question

I try to persist my Department and Mandator classes to hsqhldb but it gives this error.

Exception Description: [class ch.printsoft.         


        

Answer 1

Remove mappedBy from @OneToMany annotations from Mandator class

Check if all related classes are mapped as @Entity. Department class has @ManyToMany relation to DocumentUser. Provide the listing of DocumentUser class
