Hi,
Does any one have a working mapping of a bidirectional n:m relationship that
they could share? I've been trying with various settings with no luck. My
current xdoclet declarations for the relationship between Organsiation and
Period entities are below, but I'm getting the exception listed below the code.
/**
* @ejb.relation
* name="Organisation-Period"
* role-name="periods-have-organisations"
* @weblogic.column-map
* key-column="C_ID"
* foreign-key-column="C_PERIOD_ID"
* @weblogic.relation
* join-table-name="MPRS_ORGANISATION_PERIOD_JOIN"
* @ejb.interface-method
* view-type="local"
* @ejb.value-object
* aggregate="au.gov.qld.des.mprs.dto.OrganisationTransferObject"
* aggregate-name="Organisation"
* members="au.gov.qld.des.mprs.ejb.OrganisationLocal"
* members-name="OrganisationLocal"
* relation="external"
* type="java.util.Collection"
*/
public abstract Collection getOrganisations();
