"PUT" request isn't processed

Question

I have a jquery script that sends data to my spring controller using PUT type. But controller never gets hit. If i change PUT to POST everything works as expected, but i need to use exactly PUT. Could you please review my code and tell me what i am doing wrong?

jQuery

var values = $("form").serialize();
                $.ajax({
                    type: "PUT",
                    url: "/user/" + elogin.val(),
                    async: false,
                    data: values,
                    success: function(resp) {\\doStuff}
                 })

Controller

@Controller
@RequestMapping(value = "/user")
public class RestController {

    @RequestMapping(value = "/{userLogin}", method = RequestMethod.PUT)
    @ResponseBody
    public boolean updateUser(@PathVariable String userLogin,
                              @RequestParam("epassword") String password,
                              ...)
            throws ParseException {
        if (...) {
            return false;
        }
        \\doStuff
        return true;
    }
}

Solved by adding to web.xml

<filter>
    <filter-name>HttpPutFormContentFilter</filter-name>
    <filter-class>org.springframework.web.filter.HttpPutFormContentFilter</filter-class>
</filter>

<filter-mapping>
    <filter-name>HttpPutFormContentFilter</filter-name>
    <url-pattern>/*</url-pattern>
