Thanks Matthew -
Looking at number 4 in your example, it looks like you have an
ExceptionMapper per specific Exception type - ie - there's a mapper for
every subclass of ServiceException rather than one catch-all for
ServiceException. I'm trying to avoid that and the docs lead me to believe
it's possible, but I can't get it working.
Thanks for your detailed example!
