Ajax Call to spring servlet could not initiate oauth2 dance for IBM connection cloud - ibm-sbt

Question

I am trying to make an ajax call from my web page to my spring servlet which then has to retrive the data from connections cloud using SBT oauth2 endpoint. The ajax call is working fine for other servlets but failing to do oauth2 dance.
Here is my ajax function in jquery.
$.ajax({
url: 'getmycontacts',
type: 'GET',
cache: false,
success: function(res) {
alert("in success");
console.log(res);
document.getElementById('returnmsg').innerHTML = res;
alert(res);
},
error : function(xhr,ajaxOptions,thrownError){
console.log("in error");
console.log(xhr.responseText);
console.log("status code.."+(xhr.status));
}
});
Java servlet
#RequestMapping(value ="/getmycontacts", method = RequestMethod.GET)
public #ResponseBody String getmycontacts(HttpServletRequest request,
HttpServletResponse response){
String message ;
try {
ProfileService service = new ProfileService("smartcloudOA2"); //If no endpoint is specified, it uses default end point i.e connections
ProfileList profiles = service.getMyContacts();
String id = service.getMyProfile().getDisplayName();
if(profiles!=null && !profiles.isEmpty())
{
message = id;
}
else { message ="no result"; }
} catch (Throwable e) {
message = e.getMessage();
}
return message ;
I get the following error
