Hi Reinhard,
just in case you missed my other email about altering your mapping file,
here's the mapping file I have used to marshall an instance of A
according to your desired output.
<?xml version="1.0" ?>
<!DOCTYPE mapping PUBLIC "-//EXOLAB/Castor Mapping DTD Version 1.0//EN"
"http://castor.org/mapping.dtd";>
<mapping xmlns:r="http://xyz.com";>
<!-- this mapping has not yet been pimped to qualify attributes -->
<class name="xml.reinhard2.A">
<map-to xml="OBJECT" ns-uri="http://xyz.com"; ns-prefix="p" />
<field name="name" type="string">
<bind-xml name="r:objectName" node="attribute" />
</field>
<field name="strings" collection="map" type="xml.reinhard2.B"
set-method="addString"
get-method="getStrings">
<bind-xml name="STRING" node="element" />
</field>
</class>
<class name="org.exolab.castor.mapping.MapItem">
<field name="key" type="string" transient="true" />
<field name="value" type="xml.reinhard2.B" container="true" />
</class>
<class name="xml.reinhard2.B">
<map-to ns-uri="http://xyz.com"; ns-prefix="p" />
<field name="name" type="string">
<bind-xml name="r:name" node="attribute" />
</field>
<field name="value" type="other">
<bind-xml node="text" />
</field>
</class>
</mapping>
Regards
Werner
