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 > Now I've finally arrived at the following error: > > "The method getExtraParametersList/isExtraParametersList in class > nikonpromosystem.PromotionType accepting/returning object of type > class nikonpromosystem.ExtraParameters was not found" 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> </ns0:ForcedPromotions> > > Do I have to try to create these methods by hand, or did I miss > something?
