criteria.add(Example.create(example).enableLike(MatchMode.ANYWHERE).ignoreCase());

tx.commit();
return result;
} catch (final HibernateException e) {
if (tx != null && tx.isActive())
tx.rollback();
logger.error(e.getMessage(),e.getCause());
}
return null;
}e as minhas classes são as seguintes
public class GradeDisciplinaPK implements Serializable {
private static final long serialVersionUID = 1L;
@ManyToOne( cascade = {CascadeType.PERSIST, CascadeType.MERGE}, targetEntity=GradeCurricular.class )
@JoinColumn(name="idgrade")
private Integer idgrade;
@ManyToOne( cascade = {CascadeType.PERSIST, CascadeType.MERGE}, targetEntity=Disciplina.class )
@JoinColumn(name="iddisciplina")
private Integer iddisciplina;
....@Entity
public class GradeDisciplina implements Serializable {
private static final long serialVersionUID = 1L;
@Id
private GradeDisciplinaPK id;
@Column(nullable = false, length = 2)
private Integer fase;
....Alguém sabe me dizer o que estou fazendo errado?
