Thanks, that's exactly what I was hoping for.
From the following link (written in mid-2005), could someone let me know
whether it's now possible to specify default XMLAdapters, as specified in
the last section "Issues"? The writer states that 'If this were for only
marshaller and unmarshaller, this can be easily done by, say, adding those
adapters to JAXBContext. But for the schema generator to work, it has to be
done declaratively, meaning that the schema generator can figure out exactly
what adapters apply without running any code.' So if you're not using schema
generator, but rather the unmarshaller, is this possible?

Also, on that same link, from the section "Sharing State Between Application
and Adapter", how is it possible to 'set configured instances of XmlAdapters
to the unmarshaller/marshaller' as described? I don't see any corresponding
methods in Unmarshaller.
Thanks.
