Again I got a little bit ahead. The missing methods I just added manually like
so:
public nikonpromosystem.ExtraParameters[] getExtraParametersList() {
//this class is virtually the same as getExtraParameters(), that was
auto-generated. I just changed the name
nikonpromosystem.ExtraParameters[] array = new
nikonpromosystem.ExtraParameters[0];
return (nikonpromosystem.ExtraParameters[])
this._extraParametersList.toArray(array);
}
public boolean isExtraParametersList(final
nikonpromosystem.ExtraParameters[] lst) {
//unfortunately there was no isExtraParameters(). I had to do
that from the scratch.
boolean retval = this._extraParametersList.equals(lst);
return retval;
}
If there's a better way, please let me know. I had to do that for every class
that had Lists.
After that the addmapping works, but unmarshal returns all nulls. So again the
code:
Mapping mapping = new Mapping(getClass().getClassLoader());
URL url1 =
getClass().getClassLoader().getResource("binding/promomap.xml");
mapping.loadMapping(url1);
XMLContext context = new XMLContext();
context.addMapping(mapping);//I go past this point now
FileReader reader = new FileReader(sFileName);
nikonpromosystem.PromoCall promocall = (nikonpromosystem.PromoCall)
unmarshaller.unmarshal(reader);
//The unmarshal works but all fields inside promocall are null. When I
step into this statement, It only executes the constructor, which calls the
PromoCallType constructor which creates new lists and returns.
I also tried to unmarshal into the type object
nikonpromosystem.PromoCallType promocall =
(nikonpromosystem.PromoCallType) unmarshaller.unmarshal(reader);
but the result is the same - all fields are null.
Here's the mapping of the PromoCall:
<class name="nikonpromosystem.PromoCall" access="shared">
<map-to xml="PromoCall" element-definition="true"/>
</class>
Now I noticed that all type classes in the mapping are trying to map to the xml
names like so, but in the xml there's no PromoCallType tag, because it's a type
that's only defined in the scheme.
<class name="nikonpromosystem.PromoCallType" access="shared">
<map-to xml="PromoCallType" element-definition="false"/>
<field name="promoCallID" type="nikonpromosystem.PromoCallID" required="true">
<bind-xml name="PromoCallID" node="element"/>
</field>
<field name="account" type="nikonpromosystem.Account">
<bind-xml name="Account" node="element"/>
</field>
:
:
</class>
How can I make it work?
Hi,

Hmm, that should not be required. Can you please raise a Jira issue and
attach a very simple sample for us to reply this ?
Sure, http://jira.codehaus.org/browse/CASTOR-2701

That indicates that in your mapping you have a field mapping for a
property 'extraParametersList' with a type of 'ExtraParameters'. Is that
meant to be a collection or not ? How does the mapping for this one
property look like ?
Here's the relevant mapping section:
<class name="nikonpromosystem.PromoParameterType" access="shared">
<map-to xml="PromoParameterType" element-definition="false"/>
.
.
.
<field name="extraParametersList" type="nikonpromosystem.ExtraParameters">
<bind-xml name="ExtraParameters" node="element"/>
</field>
.
</class>
Here's the relevant schema section:
<xs:complexType name="PromotionType">
<xs:sequence minOccurs="1" maxOccurs="1">
<xs:element name="promoSource">
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:enumeration value="ORDERENTRY" />
<xs:enumeration value="PROMOSYSTEM" />
</xs:restriction>
</xs:simpleType>
</xs:element>
<xs:element name="promotionID" type="xs:string" />
<xs:element name="promotionName" type="xs:string" />
<xs:element minOccurs="0" maxOccurs="unbounded" name="ExtraParameters"
type="PromoParameterType" />
</xs:sequence>
</xs:complexType>
<xs:complexType name="PromoParameterType">
<xs:sequence>
<xs:element name="parameterName" type="xs:string" />
<xs:element name="parameterType">
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:enumeration value="IMAGEPATH" />
<xs:enumeration value="INVOICEMESSAGE" />
<xs:enumeration value="AGENTMESSAGE" />
<xs:enumeration value="INPUTPARAMETER" />
</xs:restriction>
</xs:simpleType>
</xs:element>
<xs:element name="parameterValue" type="xs:string" />
</xs:sequence>
</xs:complexType>
This is the xml:
<ns0:ForcedPromotions>
<ns0:promoSource>ORDERENTRY</ns0:promoSource>
<ns0:promotionID>130</ns0:promotionID>
<ns0:promotionName>NIKON COUPONS 1</ns0:promotionName>
<ns0:ExtraParameters>
<ns0:parameterName>COUPON NUMBER1</ns0:parameterName>
<ns0:parameterType>INPUTPARAMETER</ns0:parameterType>
<ns0:parameterValue>12345AB</ns0:parameterValue>
</ns0:ExtraParameters>
<ns0:ExtraParameters>
<ns0:parameterName>COUPON NUMBER2</ns0:parameterName>
<ns0:parameterType>INPUTPARAMETER</ns0:parameterType>
<ns0:parameterValue>1243C</ns0:parameterValue>
</ns0:ExtraParameters>

Not really of use here. Please always try to be as specific as possible
when asking questions.
