I think you have to do two things:
* tweak the mapping (see below), and
* add an additional method to User which is important for the mapping:
public void addAuthorization(Authorization authorization)
{
authorizations.add(authorizations);
}
Now (assuming you're using betwixt 0.7) you have to tweak the mapping
using an additional mapping.xml file:
<?xml version="1.0"?>
<betwixt-config>
<class name='mms.Objects.User'>
<element name='user'>
<element name='authorizations'>
<element name='authorization'
property='authorizations'
updater='addAuthorization'/>
</element>
<addDefaults/>
</element>
</class>
<class name='mms.Objects.Authorization'>
<element name='authorization'>
<addDefaults/>
</element>
</class>
</betwixt-config>
Now prior to reading/writing via betwixt you set this mapping:
public Object readXML(Reader mappingReader, Reader xmlReader)
throws IOException, SAXException, IntrospectionException
{
BeanReader beanReader = new BeanReader();
beanReader.registerMultiMapping(new InputSource(mappingReader));
return beanReader.parse(xmlReader);
}
public void writeXML(Reader mappingReader, Writer xmlWriter,
Object obj) throws IOException, SAXException, IntrospectionException
{
xmlWriter.write("<?xml version='1.0' ?>\n");
BeanWriter beanWriter = new BeanWriter(xmlWriter);
beanWriter.getXMLIntrospector().register(new
InputSource(mappingReader));
beanWriter.enablePrettyPrint();
beanWriter.write(obj);
}
where mappingReader is a Reader that retrieves the above mapping (eg.
a FileReader or StringReader).
Hope that helps,
Tom
