@Entity
@Table(name="rutapuerto")
public class RutaPuerto{
private RutaPuertoPK pk;
private Puerto puerto;
private Ruta ruta;
private Double kilometros;
public RutaPuerto() {}
public RutaPuerto(RutaPuertoPK pk, Puerto puerto, Ruta ruta, Double kilometros) {
super();
this.pk = pk;
this.puerto = puerto;
this.ruta = ruta;
this.kilometros = kilometros;
}
@EmbeddedId
public RutaPuertoPK getPk() {
return pk;
}
public void setPk(RutaPuertoPK pk) {
this.pk = pk;
}
@Column(name="kilometros")
public Double getKilometros() {
return kilometros;
}
public void setKilometros(Double kilometros) {
this.kilometros = kilometros;
}
@ManyToOne
@JoinColumn(name="idPuerto", updatable=false, insertable=false)
public Puerto getPuerto() {
return puerto;
}
public void setPuerto(Puerto puerto) {
this.puerto = puerto;
}
@ManyToOne
@JoinColumn(name="idRuta", updatable=false, insertable=false)
public Ruta getRuta() {

public class Ruta{
public Ruta() {}
@OneToMany(mappedBy="ruta", cascade=CascadeType.REMOVE)
