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

After this I just access the Controller using below:
http://domain/SpringWebProject/json/contest/abcd
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:

Appreciate any help in this regard.

Because at this point I am running out of ideas. – Sidewheel
