I have this TABLES:
1.- PARTICIPANTE
Code:
CREATE TABLE participante (
id_participa SMALLINT NOT NULL,
nasi INTEGER NOT NULL,
PRIMARY KEY(id_participa,nasi),
FOREIGN KEY(nasi) REFERENCES persona(nasi)
)
2.- PERSONA
Code:
CREATE TABLE persona (
nasi INTEGER NOT NULL,
PRIMARY KEY(nasi)
)
3.- CITA
Code:
CREATE TABLE cita (
id_participa SMALLINT NOT NULL,
nasi INTEGER NOT NULL,
idcita INTEGER NOT NULL,
PRIMARY KEY(id_participa,idcita,nasi),
FOREIGN KEY(id_participa, nasi) REFERENCES participante(id_participa, nasi)
)
4.- FORMULARIO
Code:
CREATE TABLE formulario (
id_participa SMALLINT NOT NULL,
nasi INTEGER NOT NULL,
idcita INTEGER NOT NULL,
PRIMARY KEY(id_participa,idcita,nasi),
FOREIGN KEY(id_participa, nasi, idcita) REFERENCES cita(id_participa, nasi, idcita)
)
(among other fields, I just show you the ones that are involved in the problem)
and here are the ENTITIES:
1.- PARTICIPANTE
Code:
@Entity
@Table(name = "participante")
public class Participante implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@Column(name = "id_participa")
private Integer idParticipante;
@Id
@OneToOne
@JoinColumn(name = "nasi")
private Persona persona;
2.- PERSONA
Code:
@Entity
@Table(name = "persona")
public class Persona implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@Column(name = "nasi")
private Integer nasi;
3.- CITA
Code:
@Entity
@Table(name = "cita")
public class Cita implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@Column(name = "idcita")
private Integer idCita;
@Id
@ManyToOne
@JoinColumns({
@JoinColumn(name = "id_participa", referencedColumnName = "id_participa"),
@JoinColumn(name = "nasi", referencedColumnName = "nasi") })
private Participante participante;
4.- FORMULARIO
Code:
@Entity
@Table(name = "formulario")
public class Formulario implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@OneToOne
@JoinColumns({
@JoinColumn(name = "id_participa", referencedColumnName = "id_participa"),
@JoinColumn(name = "nasi", referencedColumnName = "nasi"),
@JoinColumn(name = "idcita", referencedColumnName = "idcita") })
private Cita cita;
And when I try to start the server I got this exception:
Code:
org.hibernate.MappingException: Unable to find column with logical name: nasi in participante
at org.hibernate.cfg.Ejb3JoinColumn.checkReferencedColumnsType(Ejb3JoinColumn.java:575)
EDIT: If I delete the "referencedColumnName" attributes I get:
Code:
Caused by: org.hibernate.AnnotationException: A Foreign key refering es.sergas.sicco.modelo.datos.dominio.participante.Participante from es.myapp.modelo.datos.dominio.cita.Cita has the wrong number of column. should be 1

Aaaaand if I split Participante properties in two like this:
Code:
@Id
@ManyToOne
@JoinColumn(name = "id_participa")
private Participante participanteId;
@Id
@ManyToOne
@JoinColumn(name = "nasi")
private Participante participanteNasi;
I get another exception:
Code:
Caused by: org.hibernate.MappingException: Foreign key (FK2EFB9FBA36C41465:cita [id_participa])) must have same number of columns as the referenced primary key (participante [nasi,id_participa])
