Hi Jon,
In method 1, there is a need for input validation, as you say... but when
there is input provided and there are parse errors, the handler simply gets
a *null* argument and is not able to catch the exception.
In method 2, the exception describes the parse error---which I want to feed
back to the submitter to debug JSON queries.
My question is, is there a way to plug into the JSON ObjectMapper
functionality that is automatically invoked in method 1 and catch the
errors?
Thanks,
Dan
