A classe OfertaDisciplina é a seguinte:


@Embeddable
public class OfertaDisciplina {
	
	@Transient
	private int qtdAlunos;
	@Transient
	private ArrayList<Inscricao> inscricoes;
	@Transient
	private Inscricao inscricao;

Estou o dia inteiro de hoje tentando resolver este erro.

#2

Ninguém conseguiu ver o erro ainda?

#3

Tem alguma coisa faltando no código? Por favor, me digam qual é o problema.

#4

Provavelmente você já resolveu o problema,mas o @OneToOne só pode ser utilizado com uma entidade.
Sua classe OfertaDisciplina está mapeada como Embeddable, portanto, o Hibernate não encontra a classe OfertaDisciplina.
Pelo visto,é só tirar o @OneToOne,que está tudo certo.
