I'm converting some bidirectional 1-n relationships no unidirectional,
once the navigation is not needed from one side, like cities and state.
I changed the relationship removing the accessor method in the blind
side and changed the ejb-jar.xml (xdoclet did that).
It's deployed ok and the tables are created ok too, with a relation
column from city (CIDADE) table to state (UF). The problem is that when
I create a city and add it to a state (UF) the relation is not added. I
tried in two differents ways :
1- getting the collection from UF, add the city into the collection and
setting the collection back to the UF (setMunicipios).
municipio = CadastroEJBGetter.getMunicipioHome().create();
municipio.setNome("Curitiba");
municipio.setSigla("CWB");
Collection c= uf.getMunicipios()
c.add(municipio);
uf.setMunicipios(uf.getMunicipios());
2 - Adding directly into the collection :
municipio= CadastroEJBGetter.getMunicipioHome().create();
municipio.setNome("Curitiba");
municipio.setSigla("CWB");
uf.getMunicipios().add(municipio);
Is there a prefered way to deal with unidirectional relations?
Here goes the ejb-jar.xml (municipio->city / UF -> state):
<!-- unidirectional -->
<ejb-relationship-role >
<ejb-relationship-role-name>uf</ejb-relationship-role-name>
<multiplicity>One</multiplicity>
<relationship-role-source >
<ejb-name>UF</ejb-name>
</relationship-role-source>
<cmr-field >
<cmr-field-name>municipios</cmr-field-name>
<cmr-field-type>java.util.Collection</cmr-field-type>
</cmr-field>
</ejb-relationship-role>
<ejb-relationship-role >
<ejb-relationship-role-name>Municipio</ejb-relationship-role-name>
<multiplicity>Many</multiplicity>
<relationship-role-source >
<ejb-name>Municipio</ejb-name>
</relationship-role-source>
</ejb-relationship-role>
</ejb-relation>
</relationships>
