RequestDispatcher null - cant find /j_spring_security_check

Hi All,
I have the following LoginBean that always returns null on a
RequestDispatcher dispatcher = ((ServletRequest) context.getRequest()).getRequestDispatcher("/j_spring_security_check");

@Component
@Scope("request")
public class LoginBean {

private String username = "";
	private String password = "";
	private boolean rememberMe = false;
	private boolean loggedIn = false;

public String doLogin() throws IOException, ServletException {
		ExternalContext context = FacesContext.getCurrentInstance()
				.getExternalContext();

RequestDispatcher dispatcher = ((ServletRequest) context.getRequest())
				.getRequestDispatcher("/j_spring_security_check");

dispatcher.forward((ServletRequest) context.getRequest(),
				(ServletResponse) context.getResponse());

FacesContext.getCurrentInstance().responseComplete();

// It's OK to return null here because Faces is just going to exit.
		return null;

}

@PostConstruct
	@SuppressWarnings("unused")
	private void handleErrorMessage() {
		Exception e = (Exception) FacesContext
				.getCurrentInstance()
				.getExternalContext()
				.getSessionMap()
				.get(
						AbstractAuthenticationProcessingFilter.SPRING_SECURITY_LAST_EXCEPTION_KEY);

if (e instanceof BadCredentialsException) {
			FacesContext
					.getCurrentInstance()
					.getExternalContext()
					.getSessionMap()
					.put(
							AbstractAuthenticationProcessingFilter.SPRING_SECURITY_LAST_EXCEPTION_KEY,
							null);
			FacesContext.getCurrentInstance().addMessage(
					null,
					new FacesMessage(FacesMessage.SEVERITY_ERROR,
							"Username or password not valid.", null));
		}
	}

public String getUsername() {
		return this.username;
	}

public void setUsername(final String username) {
		this.username = username;
	}

public String getPassword() {
		return this.password;
	}

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

public boolean isRememberMe() {
		return this.rememberMe;
	}

public void setRememberMe(final boolean rememberMe) {
		this.rememberMe = rememberMe;
	}

public boolean isLoggedIn() {
		return this.loggedIn;
	}

public void setLoggedIn(final boolean loggedIn) {
		this.loggedIn = loggedIn;
	}
}

Why dont you post login form to /j_spring_security_check directly instead of using LoginBean. What is the use of LoginBean?
