Getting started app doesn't work for me with JSON

[Brad Whitaker]

Using latest jaxrs source from github and Grails 1.3.7 I tried the
getting started app. It works fine when I post XML but if I post this
JSON I get the following error:

post:

{
"firstName": "jason",
"lastName": "works"
}

error:

Am I doing something wrong?

Thanks,

Hi Brad,

You need to add

"class":"Person"

to the JSON structure as described in the docs. Does that help?

Cheers,
Martin
