Thanks a lot for your quick response! I didn't realize that the mapping file was not needed as the descriptors were already generated. So only if there are changes to the schema at a later date, would I need to use a mapping file because I would not want to regenerate the source again (because of the changes for the marshalling code that I wrote) Thanks for developing such a useful product - I'm discovering that it really makes my task easier.

Nischala,
The xs:date type is handled by org.exolab.castor.types.Date. It has a
built in descriptor class, org.exolab.castor.types.DateDescriptor. It
can't be mapped very well with the mapping file, which is why we
provided the built-in descriptor.
If you really want to use a mapping file and not the built-in
descriptors, you can write your own custom FieldHandler that handles the
conversion to and from a string (by simply deferring to the Date.parse()
and Date.toString() methods).

Incidentally, the schema has a xd:date type.
