Thank you for your reply. 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. 2011/4/19 吕晓一 <[email protected]> > 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]] > *发送时间:* 2011年4月19日 15:33 > *收件人:* [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.
