E ae galera blza? É o seguinte: Estou tentando fazer uns testes usando JSF + Hibernate e estou apanhando rsrs… Utilizando o Hibernate XML eu consegui persistir os dados e na hora de listar os dados deu erro. Mas não é esse problema que quero resolver neste momento.
Agora estou usando Annotations e nessa nem cadastrar eu estou conseguindo. Abaixo estão os códigos que estou usando neste exemplo e logo depois o erro que está sendo apresentado:
Obs: Estou usando o Netbeans 6.1 / testei com o eclipse e o erro é o mesmo.
