i have a problem to retrieve the Collection(or ArrayList) from a Controller to jsp using ajax in Spring MVC.
The Controller code is:
ProjectController.java
@Controller
public class ProjectController {
protected final Logger log = Logger.getLogger(ProjectController.class);
@Autowired
private AziendaService service;
@RequestMapping(value ="/companyList", method = RequestMethod.GET,headers = "application/javascript")
public @ResponseBody Object getCompanyList_AJAX() {
log.info("initiale getCompanyList_AJAX method.....");
Collection<Company> collection = service.getAllCompany();
return collection;
}
}
where Company(Azienda) is Class POJO and Entity in my DBMS.
and the dispatcher-servlet.xml is:
<?xml version="1.0" encoding="UTF-8"?>

and The ajax in JSP code is: addProject.jsp
<script type="text/javascript">
$(window).load(function () {
$.ajax({
type: 'GET',
url: 'companyList.htm',
datatype:'text',
success: function(response, status, xhr) {
if(xhr.readyState == 4 &&(xhr.status == 200 || xhr.status == 0)) {
var values = [];
values = response;
$.each(values, function( index, value ) {
alert( index + ": " + value );
});
document.getElementById("loaderCompany").style.display = "none";
}
else if(xhr.readyState < 4) {
document.getElementById("loaderCompany").style.display = "inline";
}
}
</script>
I don't know why i can't retrieve the list of company in ajax. I debugged it in Chrome console and the error is GET http://localhost:8060/Project/companyList.htm 404 (Not Found).
Someone Can help me to resolve the problem??.
Thanks.
