Hi,
I have an 1-N relationship between 2 CMP EJBs, Matches and Leagues, which is set correctly (XDoclet generated). A league can have several matches, and a match can only have one league.
I'm trying to retrieve the league name, which is a league EJB field, while I'm listing every matches.
e.g. :
team 1 vs team 2 - League 1
team 3 vs team 4 - League 2...
Here is the descriptor for the relationship.
<ejb-relation >
<ejb-relation-name>MatchesLeaguesRelation</ejb-relation-name>
<ejb-relationship-role >
<ejb-relationship-role-name>MatchesHasLeague</ejb-relationship-role-name>
<multiplicity>Many</multiplicity>
<relationship-role-source >
<ejb-name>Matches</ejb-name>
</relationship-role-source>
<cmr-field >
<cmr-field-name>league</cmr-field-name>
</cmr-field>
</ejb-relationship-role>
<ejb-relationship-role >
<ejb-relationship-role-name>LeagueHasMatches</ejb-relationship-role-name>
<multiplicity>One</multiplicity>
<relationship-role-source >
<ejb-name>Leagues</ejb-name>
</relationship-role-source>
<cmr-field >
<cmr-field-name>matches</cmr-field-name>
<cmr-field-type>java.util.Collection</cmr-field-type>
</cmr-field>
</ejb-relationship-role>
</ejb-relation>
I have a finder in the League EJB, which can retrieve all the matches of a League
* @ejb.finder signature="java.util.Collection findMatches(java.lang.String aLeagueId)"
* query = "SELECT OBJECT(M) FROM League L, IN (L.match) AS M WHERE L.LeagueId = ?1"
But I don't know how to have the League name while I'm listing the matches!!!...
Perhaps, I have pissed something with XDoclet ?
Can someone help me?
Thanks a lot
