JPA (EclipseLink) Entities from Tables

Alguém tem alguma dica aí ???

:?:

:-o Owuu!!!

Seria melhor eu fazer o mapeamento sem os relacionamentos e cria-los na mão ???

Alguém tem alguma ( :idea: ) dica aí …

flws!!!

Eu msm estou tendo que responder minhas duvidas… :lol:

http://stackoverflow.com/questions/7952115/multiple-writable-mappings-exception-in-eclipselink

Este link me ajudou mas ainda fique com duvida sobre o insertable/updatable=false

se alguém puder dar umas dicas aí … estas propriedades entram no joins ??? ou @columm ???

porque isto não foi inserido automaticamente, pois criei o mapeamento auto ???

E aí… pessoal!

Inserir as anotações, a exceção anterior parou e agora está sendo mostrada está:
