415 Unsuppoted Media Type when I try send JSON to Spring MVC Controller

When I try send JSON to Spring MVC Controller I got: 

POST http://localhost:8084/springAndHibernate/greet 415 (Unsupported Media Type)

Here is declaration of method which should ,,catch" JSON:

@RequestMapping(headers ={"Accept=application/json"},value="/greet")
public String greetUser(@RequestBody Logins newLogin){

I thought it should map JSON to class Logins.java, which is here:

package newpackage;

public class Logins  implements java.io.Serializable {


 private int id;
 private String login;
 private String password;

public Logins() {
}


public Logins(int id) {
    this.id = id;
}
public Logins(int id, String login, String password) {
   this.id = id;
   this.login = login;
   this.password = password;
}

public int getId() {
    return this.id;
}

public void setId(int id) {
    this.id = id;
}
public String getLogin() {
    return this.login;
}

public void setLogin(String login) {
    this.login = login;
}
public String getPassword() {
    return this.password;
}

public void setPassword(String password) {
    this.password = password;
}

}

I send POST with jQuery ajax() method in this way:

 function onGreetingButtonClicked(e){

                var contextPath='<%=request.getContextPath()%>';
                jsonData = {
                    id: 0,
                    login: $("#loginInput").val(),
                    password: $("#passwordInput").val()
                };
                console.log(JSON.stringify(jsonData));
                console.log((contextPath + "/greet").toString());
                urlAddress = (contextPath + "/greet")

                $.ajax({type: "POST",
                    url: urlAddress, 
                    data: JSON.stringify(jsonData),
                    success: onSuccess,
                    contentType: "application/jsonp; charset=utf-8",
                    dataType: null,
                    traditional: true});
                e.preventDefault();              
            }
            function onSuccess(data){
                alert(data);
            }

When I delete

@RequestBody

from method there is no mistakes, but then I get Logins object with null as a fields value.

I would be very happy if anybody want to help me, Thank you in advance.

Based on various other postings, you should be setting the contentType to "application/javascript".

I've also seen suggestions to use "application/json", but looking at the Wikipedia page, it is clear that JSON-P is actually not valid JSON, so that MIME-type is incorrect, even though some browsers apparently know how to deal with the mistake.

At any rate, "application/jsonp" is incorrect because it is not a registered MIME-type.
