Problemas com validação em JSF

Front-end

Prezados

Estou sofrendo com um pequeno exemplo que diz que valida, mas até agora só consegui alterar as mensagens padrão de erro. Segue abaixo o código-fonte:

Classe SimpleLogin.java

package roseindia;

import javax.faces.application.FacesMessage;
import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.validator.ValidatorException;

public class SimpleLogin{
	String loginname;
	String password;

	public SimpleLogin(){}

	public String getLoginname(){
		return loginname;
	}

	public void setLoginname(String loginname){
		this.loginname = loginname;
	}

	public String getPassword(){
		return password;
	}

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

	public String CheckValidUser(){
		if(loginname.equals("chandan") && password.equals("chand")){
			System.out.println("chandan");
			return "success";
		}
		else{
			return "fail";
		}
	}
	
	public void validate(FacesContext arg0, UIComponent arg1, Object arg2)
			throws ValidatorException {
	// TODO Auto-generated method stub
	
		if (arg2.equals("")) {
			FacesMessage message = new FacesMessage();
			message.setDetail("login em branco");
			message.setSummary("login em branco");
			message.setSeverity(FacesMessage.SEVERITY_ERROR);
			throw new ValidatorException(message);
			//FacesContext.getCurrentInstance().addMessage(arg1.getClientId(arg0), message);
		}
	}
}

Validacao.java

package roseindia;

import javax.faces.application.FacesMessage;
import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.validator.Validator;
import javax.faces.validator.ValidatorException;

public class Validacao implements Validator {

	//@Override
	public void validate(FacesContext arg0, UIComponent arg1, Object arg2)
			throws ValidatorException {
		// TODO Auto-generated method stub
		
		if (arg2.equals("")) {
			FacesMessage message = new FacesMessage();
			message.setDetail("login em branco");
			message.setSummary("login em branco");
			message.setSeverity(FacesMessage.SEVERITY_ERROR);
			throw new ValidatorException(message);
			//FacesContext.getCurrentInstance().addMessage(arg1.getClientId(arg0), message);
		}

	}

}

Alguém sabe como fazer isso funcionar?
