jquery ajax callback is not working

i want to get a value through ajax call this is how i have done,

<input type="text" id="CIMtrek_CI_CER" name="CIMtrek_CI_CER" onblur="getProjectInfo()"/>

and this is what is my script,

function getProjectInfo(){
    var cerNo = document.getElementById('CIMtrek_CI_CER').value;
     $.ajax({
         type: "POST",
         url: "CIMtrek_Project_Information",
         data: {
             cerNo: cerNo
         },
         success: function (msg) {
             alert("msg : "+msg);
             document.getElementById('div_CIMtrek_CI_Used_By_ProjNo').innerHTML=msg;
         }
     });
}

and this is what is my spring method : 

 @RequestMapping(value = "/CIMtrek_Project_Information", method = RequestMethod.POST)
    public String getProjectInfotmation(@RequestParam("cerNo") String cerNo,HttpServletRequest request,HttpServletResponse response) throws Exception {
        System.out.println("cerNo : "+cerNo);

        return cerNo;
    }

controll goes to this method and prints the value also but it does not replicate in call back where i have assigned the value.

success: function (msg) {
                 alert("msg : "+msg);
                 document.getElementById('div_CIMtrek_CI_Used_By_ProjNo').innerHTML=msg;
             }

when i have used firebug the response is HTTP Status 404 - /ProjectCapexMonitoring/WEB-INF/views/81723.jsp

81723 is the input i gave with this input .jsp is added and gives this exception.

Please help me to fine what is the and resolve.

Best Regards.

If you are expecting json response and have jackson jars in your classpath

add @ResponseBody to your method

change 

@RequestMapping(value = "/CIMtrek_Project_Information", method = RequestMethod.POST)
public String getProjectInfotmation(@RequestParam("cerNo") String cerNo,HttpServletRequest request,HttpServletResponse response) throws Exception {
    System.out.println("cerNo : "+cerNo);

    return cerNo;
}

to

@RequestMapping(value = "/CIMtrek_Project_Information", method = RequestMethod.POST)
public @ResponseBody String getProjectInfotmation(@RequestParam("cerNo") String cerNo,HttpServletRequest request,HttpServletResponse response) throws Exception {
    System.out.println("cerNo : "+cerNo);

    return cerNo;
}
