Jquery Ajax using Spring 2.5.6 MVC Controller

Jquery Ajax using Spring 2.5.6 MVC Controller

I have done an ajax call as below in my jsp - 
 $(document).ready(function () {
$('#alarmsDetailsWebModel').submit(
function(event) {
$.ajax({
url : "/ratp-ssi-project-web/ui/project/modules/alarmmanagement/alarmdetails",
type : "GET",
dataType:"json",
success : function(data) {
/* data = $.parseJSON(data);
alert(data);
for (i = 0; i < data.responseHTML.length; i++){
         alert(data.responseHTML[i]);
    } */
},
error : function(xhr, status, error) {
alert(xhr.responseText);
}
});
return false;
});
});

Controller has below code - 
@RequestMapping("/project/modules/alarmmanagement/alarmdetails")
public String getAlarmDetails(Model model) {
String responseHTML = "";
alarmsDetailsWebModel adModel = new alarmsDetailsWebModel();
responseHTML = retrieveAlarmsList(adModel); // this returns list of webmodels and is then converted to JSON string using jackson jar.
return responseHTML;
}

i am unable to get the data in jsp. How do i retrieve the data (json string) in the jsp? 

PROBLEM STATEMENT / REQUIREMENT - 
keep updating a table in jsp without refreshing the page.
