Olá Pessoal,
Estou estudando JPA e peguei algumas video-aulas para ajudar, porém estou tendo problema em persistir os dados, já fiz uma busca na net mas não obtive sucesso, se alguém puder me ajudar ficarei agradecido.
O erro é o seguinte:
As Entidades mapeadas:
@OneToMany (mappedBy = "project", cascade = CascadeType.ALL, fetch = FetchType.EAGER )
private List<Iteration> iterations;
@ManyToOne(cascade = CascadeType.ALL)
@JoinColumn(name = "projectId", referencedColumnName ="id")
private Project project;
@SuppressWarnings("serial")
@Entity
@Table(schema="frasys")
public class Project implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private int id;
private String name;
private String description;
private Date lastDate;
private String location;
@OneToMany (mappedBy = "project", cascade = CascadeType.ALL, fetch = FetchType.EAGER )
private List<Iteration> iterations;
public Project() {
}
public void addIteration(Iteration iteration) {
iterations.add(iteration);
}

this.id = id;
