    CMP field for key not found:when create a cmr relationship

    Deepak Pal Newbie

      I am creating a CMR relationship b/w two entity bean(one to one bidirectional).There are two entity bean(DepartmenEntity & second is EmployeeEntity).In department primary key is employeeid & this key as a foreign key in employee table.I am trying to create a CMR relationshipb/w these two beans.I have aleady define these tags
      1.CMR relation name
      2.cmr field name
      3.target role name
      4.target entity bean
      5.& othere tag is @jboss.relation fk-column related-pk-field

      after genrating xdoclet this tag
      <key-filed>
      <field-name>employeeID
      EmployeeID</key-filed>
      </key-filed>


      <key-filed>
      <field-name>employee_ID
      Employee_ID</key-filed>
      </key-filed>

      in two different relationship tag.

      After deployment I am getting this error
      org.jboss.deployment.DeploymentException: CMP field for key not found:

      I have already searched all links they suggest to chnage the tag @jboss.relation to @jboss.target relation but after this this key filed tag removed.If anybody has any idea of this error or a full example of genrating CMT then plz send it to me on bhupendra.yaduvenshi@gmail.com.

      Thanx in advance.

          Hello,

          I had the same problem.
          This is my example : (User <-> Address)

          In UserBean :

          ...
           /**
           * @ejb.interface-method
           * view-type="local"
           *
           * @ejb.relation
           * name="user-address"
           * role-name="User-has-one-Address"
           * target-ejb="Address"
           * target-role-name="Address-has-one-user"
           * target-multiple="false"
           *
           * @jboss.target-relation
           * related-pk-field="userId"
           * fk-column="user_home_fk_id"
           * fk-constraint="true"
           *
           * @jboss.relation
           * related-pk-field="addressId"
           * fk-column="address_home_fk_id"
           * fk-constraint="true"
           *
           * @return
           */
           public abstract AddressLocal getAddress();
          ...
          


          I just use unidirectionnal relation with my oneToOne.
          userId is the primary key of User
          addressId is the primary key for Address

          Does JBoss create a new table between address and user for you ? (Does anyone know if I can use a foreign key directly in my ADDRESS table ?).

          I hope it will help you.
