Then the Internet Archive hopes that references to these archived pages will be put in place of a link that would be otherwise be broken, or a companion link to allow people to see what was originally intended by a page's authors.

Spring 3.x JSON status 406 “characteristics not acceptable according to the request ”accept“ headers ()”

Upon trying to get my response in
JSON
using
Spring 3.x
, I get the
406 error
"The resource identified by this request is only capable of generating responses with characteristics not acceptable according to the
request
"accept" headers ()."
Here is my environment
* Spring 3.2.0.RELEASE
* included jackson-mapper-asl-1.7.9.jar, jackson-core-asl-1.7.9.jar
* Tomcat 6.x
* mvc:annotation-driven in Spring configuration XML file
My Controller:
@RequestMapping("/contest")
public class ContestController {
@RequestMapping(value="{name}", headers="Accept=*/*", method = RequestMethod.GET)
public @ResponseBody Contest getContestInJSON(@PathVariable String name) {
Contest contest = new Contest();
contest.setName(name);
contest.setStaffName(new String("contestitem1"));
return contest;
My Spring Configuration file
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
After this I just access the Controller using below:
and the response I get is Status 406: "The resource identified by this request is only capable of generating responses with characteristics not acceptable according to the request "accept" headers ()."
I also tried an alternate mechanism by access this using
Javascript
AJAX
to make sure my request header has
application/JSON
but this led to the same Status 406 result
$.getJSON('contest/abcd', function(data) {
console.log(data) }
Here is my REQUEST HEADER captured from browser:
Request URL:http://localhost:8080/SpringWebProject/json/contest/abcd
Request Method:GET
Status Code:406 Not Acceptable
Accept:application/json, text/javascript, */*; q=0.01
Accept-Charset:ISO-8859-1,utf-8;q=0.7,*;q=0.3

There is nothing wrong in your configuration, let me suggest a few small changes though:
a) Your namespaces appear wrong - they are referring to the 3.0 schemas, just change them to either 3.1 one's or don't refer to the version explicitly, this way for eg.
xsi:schemaLocation="
OR
xsi:schemaLocation="
b) You don't require the ContentNegotiatingViewResolver, you can remove everything but the
component-scan
and
from your configuration
c) The request will not directly work from the browser as it explicitly requires an Accept header of "application/json" -
$.getJson
call should work though as it sends the correct headers
d) Remove the
headers=Acc..
from the @RequestMapping, and produces also, both are filtering criteria to match up the correct mapped method call.
With these, there is no reason why the json should not get served out, can you please try with these and see how it goes.

I tried all that you had suggested and also removed version references. No difference though :( here is the mapping information at start up and my JSON request is same as before
INFO: Mapped "{[/contest/{name}],methods=[GET],params=[],headers=[],consumes=[],produces= [],custom=[]}" onto public com.contestframework.model.Contest com.contestframework.controllers.ContestController.getContestInJSON(java.lang.String)
If you find time, I could send you my exported eclipse project also. Because at this point I am running out of ideas.

Yes, if you can create a project and place it on github, I can try to fix it and send you a pull request.

The issue with your project was actually very small - you have protected getters in your Contest class, just change it to public methods and it should just work cleanly.

I have also just experienced this same issue. It would appear it is an issue with the latest 3.2.0.RELEASE, as I previously had 3.1.2.RELEASE and it all worked. After changing to 3.2.0.RELEASE it breaks. Have tested with 3.1.3.RELEASE and that works fine. So for now I would suggest rolling back to 3.1.3.RELEASE
EDIT: Thanks to another post on this site that linked to the following location:
I've now got it working by disabling the getting of media type based on the extension of the requested path. This can be done by the following:
And specify version 3.2 for all the xsd schema locations.
And this is using the following jackson jars:

I think you need to add a produces="application/json" to your @RequestMapping (haven't looked at spring mvc in a while so i'm not 100% positive) ...
16.3.2.6 Producible Media Types
You can narrow the primary mapping by specifying a list of producible media types. The request will be matched only if the Accept request header matches one of these values. Furthermore, use of the produces condition ensures the actual content type used to generate the response respects the media types specified in the produces condition. For example:
@Controller
@RequestMapping(value = "/pets/{petId}", method = RequestMethod.GET, produces="application/json")
@ResponseBody
public Pet getPet(@PathVariable String petId, Model model) {
// implementation omitted

I just tried that after reading your comment. It gives back the same result status 406. Confirmed the same when server starts the mapping is done correctly with produces option --
INFO: Mapped "{[/contest/{name}],methods=[GET],params=[],headers=[],consumes=[],produces=[application/json || */*],custom=[]}" onto public com.contestframework.model.Contest com.contestframework.controllers.ContestController.getContestInJSON(java.lang.String)

@les2, that worked!! I have struggling with the problem, tried adding HttpServletResponse and set content type to "application/json", it wouldn't resolve. 'produces' attribute worked for me.

Don't make the same mistake I did, spend all day playing around with Spring configuration, when actually your object returned in a web service is not marshaling to XML correctly. It seems Spring catches a JAXB marshaling error and doesn't report it. Use this sandbox code to validate JAXB marshaling:
MyClass myclass = new MyClass();
//populate myclass here
JAXBContext context = JAXBContext.newInstance(MyClass.class);
Marshaller m = context.createMarshaller();
StringWriter w = new StringWriter();
m.marshal(myclass, w);
System.out.println(w);
This produced and displayed an exception. Fixed the cause, and my web service is available in both XML and JSON.

Shortly:
For Spring MVC 4.1.6 there is enough:
jackson-databind
has dependency on
core
and
annotations
artifacts.
In details:
What is
HTTP 406
error?
406 Not Acceptable
The requested resource is only capable of generating content not acceptable according to the Accept headers sent in the request.
It means that Server cannot generate content which
MEDIA TYPE
stated in
Accept
Header.
But how does server know which
MEDIA TYPE
it can generate and which not?
Spring Web has concept of
HttpMessageConverter
. Some of these converters are already registered in Spring and
AbstractMessageConverterMethodArgumentResolver
holds them in property
messageConverters
During request processing
AbstractMessageConverterMethodProcessor
analyzes what spring can convert and saves all supported
MEDIA TYPES
in
producibleMediaTypes
variable.
If requested
MEDIA TYPE
is not producible then says Error 406 == I cannot generated requested media type. Sorry.
To cut the long story short - register required converters. In your case it's jackson library which produces
application/json

Please, see
As you can see
"For file extensions in the request URI, the MVC Java config and the
MVC namespace, automatically register extensions such as .json, .xml,
.rss, and .atom if the corresponding dependencies such as Jackson,
JAXB2, or Rome are present on the classpath."
You should add ".json" at the end of URI (like
It works for me.
