Re: How to use the attribute tag?

[Thomas Cornet]

Attributes only work with a query customizer. A query customizer implements 
interface org.apache.ojb.broker.accesslayer.QueryCustomizer and allows you 
to modify the way the collections is created.

Your repository.xml should look like this :

<collection-descriptor
        name="liste"
        ...
>
        <inverse-foreignkey field-ref="..."/>
        <query-customizer class="package.YourQueryCustomizer">
                <attribute attribute-name="<paramName>" 
attribute-value="<paramValue>" />
        </query-customizer>
</collection-descriptor>

For a little miore info, see the bottom of page '/doc/tutorial3.html'.

Hello all!

I'm using OJB, and want to load all InventaireTable of a TransportFiche 
where the InventaireTable.typeVisiteDossier=2
to do this I use the attribute tag using : <attribute 
attribute-name="typeVisiteDossier" attribute-value="2"/>. But OJB load all
InventaireTable of the TransportFiche including typeVisiteDossier=1. I 
think the repository.xml is bad configured or the attribute
tag was created to do this. I don't know what is wrong. Could someone help 
me please.

Fragment of the repository.xml:

<!-- Definitions for com.mps.safari.gestion.TransportFiche -->
<class-descriptor class="com.mps.safari.gestion.TransportFiche" 
table="trajet">
     <field-descriptor id="1" name="id" column="TRAJET_ID" 
jdbc-type="BIGINT" primarykey="true" autoincrement="true"/>
     ...
     <collection-descriptor name="inventaires" 
element-class-ref="com.mps.safari.gestion.InventaireTable">
          <inverse-foreignkey field-ref="codeVisiteDossier"/>
          <attribute attribute-name="typeVisiteDossier" attribute-value="2"/>
     </collection-descriptor>
</class-descriptor>

<!-- Definitions for com.mps.safari.gestion.InventaireTable -->
<class-descriptor class="com.mps.safari.gestion.InventaireTable" 
table="inventaire">
     <field-descriptor id="1" name="id" column="INVENTAIRE_ID" 
jdbc-type="BIGINT" primarykey="true" autoincrement="true"/>
     ...
     <field-descriptor id="3" name="typeVisiteDossier" 
column="TYPE_VISITE_DOSSIER" jdbc-type="INTEGER"/>
     <field-descriptor id="4" name="codeVisiteDossier" 
column="CODE_VISITE_DOSSIER" jdbc-type="BIGINT"/>
     ...
   </class-descriptor>
