Galera…
To com um probleminha aki… dei algumas googladas… e pelo que entendi… o hibernate não está montando as querys…
e gostaria da ajuda de vocês pra identificar o que estou fazendo de errado…
Uso
NetBeans 6
Tomcat 6.0.16
Hibernate 3.2.5
Hibernate Annotation 3.4.0 (eu acho hehehe)
Tá dando o seguinte erro comigo:
Pelo que entendi… ele não ta conseguindo montar a query para executar…
Vou postar minhas classes para ver se ajuda na solução do problema.
