Não consigo carregar lista no minha página jsf

[pjava]

Pessoal, estou tentando carregar na minha página uma lista de escola. Acontece que não lista nada. Abaixo meus arquivos e classes.

Meu ManagedBean(MB)

@ManagedBean(name="MostraEsc")
@SessionScoped

public class MostraEscolaAtiva implements Serializable{
    
    private static final int List = 0;
    private static final int Escola = 0;
    private DataModel listaEscola;
    private List<Escola> escolas;
    private String nme;

    public String getNme() {
        nme = new EscolaDaoImp().renome();
        return nme;
    }
    public void setNme(String nme) {
        this.nme = nme;
    }
    public void handleToggle(ToggleEvent event) {  
        FacesMessage msg = new FacesMessage(FacesMessage.SEVERITY_INFO, "Fieldset Toggled", "Visibility:" + event.getVisibility());    
        FacesContext.getCurrentInstance().addMessage(null, msg);  
    }          
    public void setListaEscola(DataModel listaEscola) {
        this.listaEscola = listaEscola;
    }

    public DataModel getListaEscola(){
        List<Escola> lista = new EscolaDaoImp().list();
        listaEscola = new ListDataModel(lista);
        return listaEscola;
    }
    public List<Escola> getEscolas() {
        if(escolas.size()==0){    
            escolas = new EscolaDaoImp().findAll();  
           }   
       return escolas;
    }
    public void setEscolas(List<Escola> escolas) {
        this.escolas = escolas;
    }
}

Meu DaoImp

public class EscolaDaoImp extends AbstractDAO<Escola> implements EscolaDAO{

    private EntityManager em;    
    @Override
    public Class<Escola> getEntityType() {
        return Escola.class;
    }
    public List<Escola> list() {
        Session session = HibernateUtil.getSessionFactory().openSession();
        Transaction t = session.beginTransaction();
        List lista = session.createQuery("from Escola").list();
        t.commit();
        return lista;
    }    
    public EntityManager getEm() {
        return em;
    }
    public void setEm(EntityManager em) {
        this.em = em;
    }    
    protected EntityManager getEntityManager()  
    {  
        if (this.em == null)  
            throw new IllegalStateException("Erro");  
        return this.em;  
    }        
   @PersistenceContext  
   public void setEntityManager(EntityManager em) {  
       this.em = em;  
   }       
    public List<Escola> findAll() {    
              Query query =  getEntityManager().createQuery("select distinct e.nome " +     
                                                            "from " +    
                                                            "pessoa p inner join professor f on (p.idpessoa = f.idpessoa) " +    
                                                            "inner join matricula m on (m.idprofessor = f.idprofessor) " +    
                                                            "inner join escola e on (e.idescola = m.idescola)" +    
                                                            "where m.situacao = 'A'");    
              return (List<Escola>) query.getResultList();    
    }    
    public String renome(){
        return "Teste";
    }
}

Meu XHTML(JSF), somente a parte que deve listar as escolas

<h:form>   
 <p:graphicImage value="/Images/ico.jpg" />                        
         <p:dataList value="#{MostraEsc.escolas}" var="escola" type="ordered"> 
                #{escola.nome}
        </p:dataList>                                    
</h:form>
