You have to execute:
SELECT d from Product d where d.name = 'toto'
d.name or d.dummy references the name you used in your mapping.xml.
<field name="name" type="String">
<sql name="nameInDb" type="char"/>
</field>
<field name="dummy" type="String">
<sql name="dummyInDb" />
</field>
Castor can not access the properties of your classes directly. It insteed calls
the getter and setter methods.
field name: dummy
property: _dummy <- castor do not take care of this properties name !!!!
getter: getDummy() { return _dummy; }
setter: setDummy(String dummy) { _dummy = dummy; }
