jQuery Servlet call returns error -

i make simplest jquery servlet call:

jquery:

$.ajax( "loginservlet" )     .done(function() { alert("success"); })     .fail(function() { alert("error"); }); 

servlet:

protected void dopost(httpservletrequest request, httpservletresponse response) throws servletexception, ioexception {   system.out.println("posting"); } 

on console, see posting, servlet called. however, still 'error' alert.

somewhere else, mentioned possible 'cross site scripting' problem. problem?

my servlet at: localhost:8080/test/loginservlet

when request servlet nothing print in console, must manage response of cycle request/response.

so try following:

 // obtain out writer stream response   // object send response client (the web page)  printwriter out = response.getwriter();  // print response of request posting  out.println("posting");  // close out stream  out.close(); 

now jquery request response.
