[Xdoclet-user] 1-1 unidirectional relationship issue.

Mick Knutson Tue, 24 Jun 2003 13:34:15 -0700

I have set up a 1-1 unidirectional relationship just like the xPetstore, but it does not seem to work at all. I don't get errors, but the relationship does not update. I have a MedicalHistoryDto that has an AllergiesDto. I can populate the Allergies by itself like a standalone bean, but not like medicalHistoryDto.setAllergiesDto( allergiesDto );

My Code:
=========================
   /**
    * Get Allergies for this medicalHistory.
    *
    * @ejb.interface-method
    *
    * @ejb.relation
    *      name="MedicalHistory-Allergies"
    *      role-name="medical_history-has-allergies"
    *      target-ejb="Allergies"
    *      target-role-name="allergies-belongs_to-medical_history"
    *      target-cascade-delete="yes"
    *
    * @ejb.value-object
    *      compose="com.baselogic.yoursos.user.AllergiesDto"
    *      compose-name="AllergiesDto"
    *      members="com.baselogic.yoursos.user.AllergiesLocal"
    *      members-name="AllergiesDto"
    *      relation="external"
    *
    * @jboss.relation
    *      fk-column="allergies_id_fk"
    *      related-pk-field="medicalHistoryId"
    *      fk-contraint="true"
    */
   public abstract AllergiesLocal getAllergies();
   public abstract void setAllergies( AllergiesLocal pAllergiesLocal );


   /**
    * Retrieve the MedicalHistory's ID.
    *
    * @ejb.pk-field
    * @ejb.persistent-field
    * @ejb.interface-method
    * @ejb.transaction
    *      type="NotSupported"
    * @jboss.column-name name="medical_history_id"
    **/
   public abstract java.lang.String getMedicalHistoryId();

/** * No interface method for setMedicalHistoryId(..). See page 130 of the EJB 2.0 specification: * "Once the primary key for an entity bean has been set, the Bean Provider must * not attempt to change it by use of set accessor methods on the primary key * cmp-fields. The Bean provider should therefore not expose the set accessor * methods for the primary key cmp-fields in the component interface of the * entity bean.". A work around would be to remove and then an re-create the bean. */ public abstract void setMedicalHistoryId( java.lang.String pMedicalHistoryId );
