Problema com JSF

Front-end
#1

Bem pessoal, estou começando agora com JSF e não estou conseguindo rodar seguinte exemplo:

MeuBean

package meupacote;

import javax.faces.application.FacesMessage;
import javax.faces.context.FacesContext;
public class MeuBean 
{
	private String nome = null;
	
	public void setNome(String nome)
	{
		this.nome = nome;
	}
	
	public String getNome()
	{
		return nome;
	}
	
	public String acao()
	{
		boolean sucesso = true;
		FacesContext context = FacesContext.getCurrentInstance();
		
		if(nome != null)
		{
			for(int i = 0; i < nome.length(); i++)
			{
				char c = nome.charAt(i);
				
				if(!(Character.isLetter(c)) && ! Character.isSpaceChar(c))
				{
					String msg = "Digite somente caracteres alfabéticos.";
					
					FacesMessage message = new FacesMessage(msg);
					
					context.addMessage("formulario", message);
					
					sucesso = false;
					break;
				}
			}
		}
		else
		{
			sucesso = false;
		}
		
		return (sucesso ? "sucesso" : "falha");
	}
}
