Erro ao deletar objeto com JSF e Hibernate!

Front-end
#1

Pessoal, estou conseguindo listar os objetos do meu banco, mysql, mas quando clico no link para excluir não acontece nada!
Alguém poderia me dá uma ajuda?
segue os meu códigos:
quando tento deletar aparece isso:

INFO: building session factory
25/02/2011 20:45:51 org.hibernate.impl.SessionFactoryObjectFactory addInstance
INFO: Not binding factory to JNDI, no JNDI name configured
Hibernate: 
    select
        this_.id_paciente as id1_17_0_,
        this_.bairro_acomp as bairro2_17_0_,
        this_.bairro_paci as bairro3_17_0_,
        this_.cor_acomp as cor4_17_0_,
        this_.cor_paci as cor5_17_0_,
        this_.cpf_acomp as cpf6_17_0_,
        this_.cpf_paci as cpf7_17_0_,
        this_.data_nas as data8_17_0_,
        this_.data_nasacomp as data9_17_0_,
        this_.nome_acomp as nome10_17_0_,
        this_.nome_paci as nome11_17_0_,
        this_.numero_acomp as numero12_17_0_,
        this_.numero_paci as numero13_17_0_,
        this_.rg_acomp as rg14_17_0_,
        this_.rg_paci as rg15_17_0_,
        this_.rua_acomp as rua16_17_0_,
        this_.rua_paci as rua17_17_0_,
        this_.sexo_acomp as sexo18_17_0_,
        this_.sexo_paci as sexo19_17_0_ 
    from
        paciente this_

Agora o código do Dao

public class Dao<T> {
    private Class persistentClass;
    protected Session session;
    protected Session getSession(){
        return session;
    }
    public Dao(Session session, Class persistentClass){

        this.session = session;
        this.persistentClass = persistentClass;
    }
...
    public void delete(T t){
        session.delete(t);
    }

BaseFacade:

public interface  BaseFacade<T> extends Serializable {
...
   public abstract void remove(T t);

PacienteFacade

public interface PacienteFacade extends BaseFacade<Paciente> {
     public void remove(Paciente paciente);

PacienteFacadeImpl

public class PacienteFacadeImpl implements PacienteFacade {
    private static final long serialVersionUID = 1818242808424001885L;

        private PacienteDao pacienteDao;
	private SessionFactory sf;
	private	Session session;
	private Transaction tx;

     public void remove(Paciente p) {
        
        sf = new AnnotationConfiguration().configure().buildSessionFactory();
	session = sf.openSession();
	tx = session.beginTransaction();
        pacienteDao = new PacienteDao(session, Paciente.class);
        pacienteDao.delete(p);

        tx.commit();
        session.close();
    }

PacienteController

public class PacienteController implements Serializable {
    private static final long serialVersionUID = -333995781063775201L;
    private Paciente paciente = new Paciente();
    private List<Paciente> lista = new ArrayList<Paciente>();    
     private Integer id;

     public String removePaciente(){
        PacienteFacade pacienteService = new PacienteFacadeImpl();
        pacienteService.remove(this.paciente);
        paciente = new Paciente();
        return "pacienteExcluido";
    }
