E aê galera blz?
Meu problema é o seguinte, Eu estou fazendo uma pequena aplicação para ilustrar o uso do padrão DAO. Aí fiz DAOS para trabalhar com JPA-Hibernate e outros DAOs para trabalhar com ODB . Estou usando as mesmas classes de entidades para trabalhar com as duas fontes de dados . Só que quando eu tento recuperar um objeto do banco orientado a objetos, causa um erro no Hiberntate, alguém pode me dizer o que está acontecendo e uma possível solução pra isso?
Aqui está o print do erro que ele causa
Error Object Oriented Persistense org.hibernate.LazyInitializationException: failed to lazily initialize a collection, no session or session was closed
