Olá pessoal,
novato tentando sair do DAO para JPA fazendo uns testes
e dando erro…
Alguém já passou por essa situação onde a tabela nota fiscal tem campo auto incremento e passa esse numero para nota fiscal item vi alguns exemplos e não sei se dessa forma está certo e está dando erro …
Exception in thread "main" Local Exception Stack:
Exception [TOPLINK-7154] (Oracle TopLink Essentials - 2006.8 (Build 060830)): oracle.toplink.essentials.exceptions.ValidationException
Exception Description: The attribute [itens] in entity class [class bar.model.NotaFiscal] has a mappedBy value of [NotaFiscal] which does not exist in its owning entity class [class bar.model.NotaFiscalItem]. If the owning entity class is a @MappedSuperclass, this is invalid, and your attribute should reference the correct subclass.
se alguém puder me ajudar agradeceria…
