Hrm, could you explain a bit more please? I was under the impression from various examples that JSON would behave like REST, eg I pass a request in a URL and the response comes back as a JSON output (eg I have a method called getMessage and it takes 3 params) so I pass it message/1/2/3/ and the output is in JSON forma- by the request wrapper you mean that I would need to pass it one object (say, a hashmap) and unwrap that object, as that is how the JSON inbound request is represented, correct? I was under the perhaps mistaken impression that JSON was extracting the values from the inbound JSON array and matching them with the arguments via Jettison.

The CXF HTTP binding requires that the service method can only have one input parameters. For example, following is invalid: @Put @HttpResource(location = "/books/{id}") void updateBook(@WebParam(name = "Book")Book c, int id); Hope this helps, Jervis > -----Original Message----- > From: Vespa, Anthony J [mailto:[EMAIL PROTECTED] > Sent: 2008?1?13? 10:33 > To: [email protected]; [email protected] > Subject: RE: Issues with JSON based Service and Jettison > > I actually tried the jax_rs samples a week or two back and it caused quite a > few issues with our codebase, as well as generally not working - it would > also require re-writes of all services, but even just re-writing one I get > exceptions and other issues - there was also some odd behavior, like not > being able to pass any data type but a String, for example, as any > arguement. > > Has anyone got a good detailed example of getting JSON to work from end > to end, with submitting a JSON formatted input into a service, and getting > appropriate output, with a configuration through beans.xml?
