Bonjour,

J'utilise une liaison oneToMany entre deux classes Entree et Entser.
Lorsque j'essaye d'ajouter une cascade entre ces deux entitées j'obtiens une exception.
Sans cascade, il n'y a pas de problème, mais il n'y a pas de sauvegarde entre Entree et Entser.
Le problème viens peut être de Spring ?
J'utilise la base oracle avec le driver jdbc 10.2.0.5.0

Voici le mapping des données :

Code:
@Entity
@Table(name = "ENTREE")
public class Entree implements java.io.Serializable {
        @GenericGenerator(name = "generator", strategy = "increment")
   @GeneratedValue(generator = "generator")
   @Id
   @Column(name = "REG_ID", unique = true, nullable = false, precision = 7, scale = 0)
   public int getRegId() {
      return this.regId;
   }

   public void setRegId(int regId) {
      this.regId = regId;
   }

[...]
        @OneToMany(fetch = FetchType.LAZY, mappedBy = "entree", cascade = CascadeType.ALL)
   public Set<Entser> getEntsers() {
      return this.entsers;
   }

   public void setEntsers(Set<Entser> entsers) {
      this.entsers = entsers;
   }
   [...]
}

@Entity
@Table(name = "ENTSER", uniqueConstraints = @UniqueConstraint(columnNames = {
      "REG_ID", "SERI_ID", "SSERI_ID", "COMNOT" }))
public class Entser implements java.io.Serializable {

        @GenericGenerator(name = "generator", strategy = "increment")
   @GeneratedValue(generator = "generator")
   @Id
   @Column(name = "ENTSER_ID", unique = true, nullable = false, precision = 22, scale = 0)
   public BigDecimal getEntserId() {
      return this.entserId;
   }

        public void setEntserId(BigDecimal entserId) {
      this.entserId = entserId;
   }

    [...]
}



Code:
