Order By Hibernate in JSF

Hello, good afternoon, I'm a beginner in this web world and I need to order establishments by punctuation (the best rated in the beginning, LOGIC)

The error is An Error Occurred: java.lang.NullPointerException

Here is my entity, any help is welcome

public class Estabelecimento implements Serializable {

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
Integer id;
@Column
String nome;
String cnpj;
String cidade;
String bairro;
String rua;
String numero;
String telefone;
int pontos;

Here is the Bean code

public List listaEstabelecimentosPontos(){
  listaEstabelecimentos =  estabelecimentoDao.ordenarPontos();
  return this.listaEstabelecimentos;
}

And here is the xml

<?xml version="1.0" encoding="UTF-8"?>

<ui:define name="content">
    <h:form>
        <p:dataTable var="tabela" value="#{estabelecimentosBean.listaEstabelecimentosPontos()}">
        <p:column headerText="Id">
            <h:outputText value="#{tabela.id}" />
        </p:column>

        <p:column headerText="nome">
            <h:outputText value="#{tabela.nome}" />
        </p:column>

        <p:column headerText="cnpj">
            <h:outputText value="#{tabela.cnpj}" />
        </p:column>

        <p:column headerText="cidade">
            <h:outputText value="#{tabela.cidade}" />
        </p:column>

        <p:column headerText="bairro">
            <h:outputText value="#{tabela.bairro}" />
        </p:column>

        <p:column headerText="rua">
            <h:outputText value="#{tabela.rua}" />
        </p:column>

        <p:column headerText="numero">
            <h:outputText value="#{tabela.numero}" />
        </p:column>

        <p:column headerText="telefone">
            <h:outputText value="#{tabela.telefone}" />
        </p:column>

        <p:column headerText="AÇÕES">
              <center>
              <p:commandButton value="Remover" action="#{estabelecimentosBean.removerEstabelecimento(tabela)}" />
              <p:commandButton value="Editar" action="#{estabelecimentosBean.atualizarEstabelecimento(tabela)}" />
              </center>
        </p:column>

     </p:dataTable>
  </h:form>
</ui:define>
