Thanks Serafin, I will keep this solution
in mind.

Re: custom exception
mappers and core exceptions/errors
As I said our requirements was quite different. But in
case you could not achieve it with just exceptionMapper (which I don't
know) I let you know how our custom solution could help you.

So you couldn't do it just in an exceptionMapper?
I was hoping to avoid having to rewrite too much of the core wink dispatcher,
but it sounds like you went in deep and extended the internals.
Surely there must be a way to achieve this without having to extend the
RequestProcessor and DeploymentConfiguration.

Hi,
We've done something similar.
We extended RequestProcessor and DeploymentConfiguration. Then
in the constructor ExtendedRequestProcessor we set our ExtendedDeploymentConfiguration.
What did the trick for us was to extend the ResourceRegistry and add it
in the ExtendedDeploymentConfiguration. This ExtendedResourceRegistry has
the findMethod and findSubResourceMethod custom implementation
that allows the throw of our own Exception.
Regards.
Serafín.

I am trying to use a custom exception mapper to format all exceptions into
my desired xml/json types depending on the content type.
I am handling my own exceptions happily and returning the http status code
I want, and the right xml/json response with the right helper messages,
but when it comes trying to catch wink errors such as a url/method/body
being wrong and not matching a handler I am struggling. I want to handle
these myself because wink does not format them into xml/json, and if it
did, would still be choosing its own format rather than mine.
I have an exceptionMapper which handles WebApplicationException but from
the exception I get there, I cannot figure out how to get a description
of the cause. I can get the stack, which normally isn't helpful, and I
can get the http status code from the response, but trying to get a string
saying "there is no handler for method PUT on resource /wibble/"
seems to be impossible.
Has anyone attempted this? Did you find a solution?
The closest I can get is parsing the http status code and writing a description
stream for each, but then I have to parse the Request object to work out
what the user called. I would have thought wink has already done some of
this for me.
