I'm not sure whether '_' is allowed as the first character for
property names. It would be easiest if you name the getter and setter
methods following the standard Java conventions, eg. like this:
Interface Taille
{
int getLargeurColonne();
....
}
Class TailleStructure implements Taille
{
int _LargeurColonne;
public int getLargeurColonne(){...}
public void setLargeurColonne(int att){...}
}
Class Document
{
Taille _TailleCommandee;
.....
public
public Taille getTailleCommandee(){...}
public void setTailleCommandee(Taille newTaille){...}
}
Class Maquette extends Document
{
BigDecimal _Numero;
public Maquette()
{
_TailleCommandee = new TailleStructure ();
}
....
}
and in the repository xml you then simply specify
<class-descriptor class='Maquette' table='maquette'>
<field-descriptor name="numero" column="numero" jdbc-type="numeric"
primarykey="true" access="readonly" autoincrement="true"/>
.....
<!-- taille -->
<field-descriptor name="tailleCommandee::largeurColonne"
column="nb_largeurcolcommandee" jdbc-type="INTEGER"/>
</class-descriptor>
(notice the missing '_' and that the first letter is lowercase)
This way you'll avoid problems with Java's introspection.
