Issue accessing JSON returned from my REST Api

Issue accessing JSON returned from my REST Api

I have my Webservice(REST Api)   http://localhost:8080/SpringDataSource/rest/emps.json which is running in my localhost ( http://localhost:8080/SpringDataSource/rest/emps.json) returns a json as shown below ,

[{"id":3,"name":"biathlon","role":"10000"},{"id":4,"name":"skijumping","role":"nh"},
{"id":5,"name":"speedskating","role":"1000"}]

I have this piece of JQuery code which is executed from a html file to hit the webservice to get the response,

function doGet() {
$.ajax({
   type: 'GET',
    url: 'http://localhost:8080/SpringDataSource/rest/emps.json&jsoncallback=?',
    contentType: "application/json",
    dataType: 'json',
    success: function(json) {       
        alert('sucess');
        alert(json);
    },
    error: function(jqXHR, exception) {
            eval
            alert(jqXHR.responseText);
            if (jqXHR.status === 0) {
                alert('Not connect.\n Verify Network.');
            } else if (jqXHR.status == 404) {
                alert('Requested page not found. [404]');
            } else if (jqXHR.status == 500) {
                alert('Internal Server Error [500].');
            } else if (exception === 'parsererror') {
                alert('Requested JSON parse failed.');
            } else if (exception === 'timeout') {
                alert('Time out error.');
            } else if (exception === 'abort') {
                alert('Ajax request aborted.');
            } else {
                alert('Uncaught Error.\n' + jqXHR.responseText);
            }
        }
});
}

On calling this function the GET request is triggered, it hits my Webservice and the response is obtained(I made sure by tracking the Network packets using Chrome's Inspect Element feature) and the response is as expected(shown below),
[{"id":3,"name":"biathlon","role":"10000"},{"id":4,"name":"skijumping","role":"nh"},{"id":5,"name":"speedskating","role":"1000"}]

but I am getting  exception === 'parsererror' . I am not sure how to resolve this issue because the response is obtained correctly but not able to get through Jquery parser. Please help me to resolve this issue.

I am using JQuery from Google's CDN
