JSF 2.0: how to redirect to a secure page after using HttpServletRequest.login

I am trying to use HttpServletRequest.login with form-based validation.

Everything is in order (the container says that the username / password is good), except that after the user has entered his username, I do not know how to redirect the user to the protected page that he requested (the login form is redrawn). How to do it?

Thanks in advance for your help.

The code:

web.xml:

<login-config>
    <auth-method>FORM</auth-method>
    <realm-name>security</realm-name>
    <form-login-config>
        <form-login-page>/faces/loginwithlogin.xhtml</form-login-page>
        <form-error-page>/faces/noaut.xhtml</form-error-page>
    </form-login-config>
</login-config>

Loginwithlogin.xhtml page

<html xmlns="http://www.w3.org/1999/xhtml"
  xmlns:h="http://java.sun.com/jsf/html"
  xmlns:f="http://java.sun.com/jsf/core">
    <h:head>
        <title>Authentication</title>
    </h:head>
    <h:body>
        <h:form>
            Login :
            <h:inputText value="#{login.login}" required="true" />
            <p/>
            Mot de passe :
            <h:inputSecret value="#{login.password}" required="true" />
            <p/>
            <h:commandButton value="Connexion" action="#{login.submit}">
                 <f:ajax execute="@form" render="@form" />
            </h:commandButton>
            <h:messages />
        </h:form>
    </h:body>
</html>

Update: without Ajax, it does not work.

Bean support:

@Named
@SessionScoped
public class Login implements Serializable {
  private String login;
  private String password;
  // getters and setters 
  ...

  public void submit() {
    FacesContext context = FacesContext.getCurrentInstance();
    HttpServletRequest request = 
            (HttpServletRequest) context.getExternalContext().getRequest();
    try {
        request.login(login, mdp);
        context.addMessage(null, 
                new FacesMessage(FacesMessage.SEVERITY_INFO, 
                "OK", null));
    } catch (ServletException e) {
        context.addMessage(null, 
                new FacesMessage(FacesMessage.SEVERITY_ERROR, 
                "Bad login", null));
    }
  }

, RequestDispatcher#forward(), URI , RequestDispatcher#FORWARD_REQUEST_URI. ( , ) JSF, ExternalContext#getRequestMap().

, :

private String requestedURI;

@PostConstruct
public void init() {
    requestedURI = FacesContext.getCurrentInstance().getExternalContext()
        .getRequestMap().get(RequestDispatcher.FORWARD_REQUEST_URI);

    if (requestedURI == null) {
        requestedURI = "some/default/home.xhtml";
    }
}

public void submit() throws IOException {
    // ...

    try {
        request.login(username, password);
        externalContext.redirect(requestedURI);
    } catch (ServletException e) {

    }
}

bean @ViewScoped (JSF) @ConversationScoped (CDI) @SessionScoped ( @RequestScoped; <f:param> , <f:viewParam>).
