It works fine, but now, I'm having another problem related to this. When I marshall the object, the vehicle tags in the xml file doesn't contain the xsi:type attribute. For that reason, when I unmarshall the object I get an error. Do you know how can I specify this attribute in the mapping file so that it appears in the resultant xml file? I've tried using the type attribute of <bind-xml> tag but it doesn't work. Thank you very much. Hi, here is an example. <myClass> <vehiclelist> <vehicle/> <vehicle/> </vehiclelist> </myClass> You should define a Vehicle class and a mapping-file for it, and you should include this mapping-file in the main mapping-file <include href=”VehicleMap.xml”/> <class name="your.package.MyClass" auto-complete="true"> <map-to xml="myClass"/> <field name="vehicles" type="your.package.Vehicle" collection="arraylist"> <bind-xml name="vehicle” node="element" location="vehiclelist"/> </field> </class> 发件人: Jose Antonio [mailto:[email protected]<mailto:[email protected]>] 发送时间: 2011年4月19日 15:33 收件人: [email protected]<mailto:[email protected]> 主题: [castor-user] Exception while mapping a java.util.List attribute Hello, I've got a problem mapping a class whose one of its attributes is a java.util.List.

For example, if the attribute is: private List<Vehicle> vehicles; I want this attribute to be mapped with the name "myVehicles" in the xml file. What I have done in the mapping file is: <class name="MyClass" auto-complete="true"> <map-to xml="myClass"/> <field name="vehicles"><bind-xml name="myVehicles"/></field> </class> Please, if anyone knows what it is happening, help. Thanks in advance
