How have you built this interface? I assume you haven't used
Seaside-REST [1]. It works in theory with VAST but you'll have to use
positional arguments in the path patterns instead of argument names
which is a bit less nice.

There are several ways this can be done all depending on your needs.
In theory at any point during request processing you can just return
JSON with:
self requestContext respond: [ :response |
response
contentType: WAMimeType applicationJson;;
nextPutAll: '{"railroadName": "Sunset & North Eastern RR"}' ]
However doing that in a Seaside application with components doesn't
make a whole lot if sense if it isn't needed for AJAX. So my next step
would be ask for more information about your REST interface. How large
is it? What features do you need?
BTW we also have a canvas API for building JSON WAJsonCanvas ;-)
