Hi Hani, I know(discovered) I cannot have both tags. I already have the ejb.relation tags as all my relationships are bidirectional right now. My problem is that with just those tags, the orion module doesn't do anything to add information, regarding the relationships, to the orion-ejb-jar.xml, so Orion does not know which fields to use for them. Let's see: if I have two tables like that: T_A(A_ID, A_NAME); T_B(B_ID, B_NAME, B_A_ID); with a 1-N bidrectional relationship using B_A_ID as FK in T_B, what is the supposed way to describe that so Orion automatically handles that relationship? If you don't add some info on orion-ejb-jar.xml, how does orion guess that the FK field is B_A_ID? So far, for Resin, what I used to do is the following: //On TB entity /** * @ejb:interface-method view-type="local" * @ejb:relation * name="t_b-t_a" * role-name="t_b-has-t_a" * @resin-ejb:relation sql-column="B_A_ID" */ public abstract pkg.TALocal getTA(); //on TA /** * @ejb:interface-method view-type="local" * @ejb:relation * name="t_b-t_a" * role-name="t_a-has-t_bs" */ public abstract java.util.Collection getTB();
All that the resin module needs is the FK SQL column, as he can guess the rest by looking at both sides of the relationship. How does one do that with Orion?

You cannot have a field have both a ejb.relation tag and a ejb.persistence tag (spec doesn't allow it, nothing to do with orion)

Hi again,
Now I'm stucked :(. If I have a relationship method and I add the
@ejb:persistent-field to that method, then Orion complains that I have the
related field declared both as cmp and cmr, which is right as it gets declared
twice. However, if I don't put it, then no information is added to the
orion-ejb-jar.xml file regarding the relationship and then Orion complains he
cannot find the match on the other side of the relationship, which is also
correct as he cannot guess the right name of the property.
Any ideas? Can this be done or is this not supported yet through the
xdoclet-orion module?
Thanks,
D.
