Hi Tim,
You do create your own reader and do all the configuration as you have
done below and then you can do the following:
UnmarshalHandler handler = myUnmarshaller.createHandler();
This will return a DocumentHandler which can then be passed to the
parser/reader:
parser.setDocumentHandler(handler);
If you need to use a ContentHandler instead of a DocumentHandler you can
do:
reader.setContentHandler(myUnmarshaller.getContentHandler(handler));
Then once you finish you parsing...
reader.parse(inputSource);
...
You can get the object that was unmarshalled by the following:
Object myObject = handler.getObject();
Hope that helps,
--Keith
