Hi Werner,
so it seems that i've tried to map the complete list instead of the list items. 1000 Thanks - it works perfectly now :) cheerz, reinhard! -----Ursprüngliche Nachricht----- Von: Werner Guttmann [mailto:[EMAIL PROTECTED] Gesendet: Mo 09.06.2008 11:16 An: [email protected] Betreff: Re: [castor-user] cannot unmarshal my marshalled xml using a mapping file Hi Reinhard, have a look at the following mapping that allows me to marshal the given Java object instances to your desired XML output structure. <mapping> <class name="xml.reinhard.A"> <description>Mapping for Class com.xyz.A</description> <map-to xml="A" ns-uri="http://xyz.com/A"; ns-prefix="a" /> <field name="strings" collection="arraylist" type="string"> <bind-xml name="string" node="element" location="b"/> </field> </class> </mapping> Please note that I changed the package when running the test(s) locally.
