jquery ajax call to java restful web service always going to error function

Hi All,

I am using jquery ajax to call restful webservice which returns a String.

But it always goes to jquery error function when call that service.

Here is the calling code:

window.onerror=function(msg,url,line){
    $('body').append(msg + ' at ' + url + ':' + line);
};


$.ajax({
                url:"http://192.168.254.25:8080/WeightsAndMeasure/restful/DerivativeCodeServic/checkIP",
                data:"derivativeCode="+$("#derivativeCode").val(),
                 type:"get",
                 dataType:"text",
                 crossDomain:true,

                           success: function (data) {
                               alert('success'+data.responseText);
                             },

                             error: function(jqXHR, textStatus, errorThrown) {
                                 throw 'aj.ERROR! [' + jqXHR.status +' '+textStatus.error + errorThrown + ']';
                             },
                        
                            complete: function (response) {
                                alert("inside success"+response.responseText);
                                }
                              });
                      
                      };});

Alert shows like this:

uncaught exception: aj.ERROR! [0 undefined] at :0


Please help in solving this issue.

Thanks in advance.
