Subject Fwd: Managing XML Output from Betwixt
Date Mon, 03 Oct 2005 16:55:59 GMT
Hi Tom,

That will help I guess ( I dint try ) but the way you explained looks like
its gonna do some magic.
Ok but heres the thing, right now I got it working the exact same way I want
I just included this line in my Main class:


and it did the trick, so now my XML is generated as I want it to be:


But may be for my future I will keep this trick in mind and try using it. I
havent actually started to use customizing the mappings of a beans to XML,
but I think in the long run its gonna help, so I am kind of reading it right
now and will definetly try the method you said.

Thanks again Russell, Tom. You guys are awesome. May be I will be back if I
get stuck up with the advanced mapping of Beans to XMl.

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)

Now (assuming you're using betwixt 0.7) you have to tweak the mapping
using an additional mapping.xml file:

<?xml version="1.0"?>
<class name='mms.Objects.User'>
<element name='user'>
<element name='authorizations'>
<element name='authorization'
<class name='mms.Objects.Authorization'>
<element name='authorization'>

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);


where mappingReader is a Reader that retrieves the above mapping (eg.
a FileReader or StringReader).

Hope that helps,
