Posting JSON data to server using DOJO

[chaitu]

I have a question on submitting JSON data to server using DOJO. I have JSON data in the below format :

{"description":"vice-president"} ---> This is stored in a javascript variable jsonData

The AJAX call is as below :

dojo.xhrPost({
   url : url, -- > url to the controller (/myContextRoot/getJsonData.do)
   content : jsonData,
   headers : {
        "Content-Type" : "application/json,charset=utf-8"
   },
   load: function(response,ioargs) {
        alert('success');
   },
   error : function(response,ioargs) {
        alert('error');
   }
});

In my controller, I have written a method as folllows :

    @RequestMapping(value = "/getJsonData.do",method=RequestMethod.POST)
    public @ResponseBody String getJsonData(@RequestBody SampleVO sampleVO) {
         System.out.println("Inside controller");
         return "success";
    }

And my value object is below :

   public class SampleVO implements Serializable {
         private String description;

         getter/setter for the above.
   }

When I perform an AJAX call to post the JSON data to the server, I am getting the error :
org.codehaus.jackson.JsonParseException : Unexpected character ('j' (code 106)) : expected a valid value (number,string,array,object,'true','false' or 'null')

I am using DOJO 1.5 and Spring 3.0

Greatly appreciate if you guys can help me find the root cause.

Thanks!
