i'm having some trouble with getting the list of person from my db and put in the tableview, here is the code:

FuncionarioViewController:

private static ObservableList listaFuncionarios = FXCollections.observableArrayList(); private FuncionarioController funcionarioController; private SessionFactory sessionFactory; private MainApp mainApp;

@FXML
private TableView<Funcionario> tableFunc;
@FXML
private TableColumn<Funcionario, String> nomeColumn;
@FXML
private TableColumn<Funcionario, Number> cpfColumn;
@FXML
private TableColumn<Funcionario, String> cargoColumn;
@FXML
private Button deleteBtn;
@FXML
private Button editBtn;
@FXML
private TextField txPesquisa;


public FuncionarioViewController() {

}
@FXML
private void initialize() {
    nomeColumn.setCellValueFactory(cellData -> cellData.getValue().nomeProperty());
    cpfColumn.setCellValueFactory(cellData -> cellData.getValue().cpfProperty());
    cargoColumn.setCellValueFactory(cellData -> cellData.getValue().cargoProperty());
    tableFunc.getSelectionModel().selectedItemProperty().addListener(
    (observable, oldValue,newValue)-> handleFuncionarioClicado(newValue));
}


public void addFunc() {
    List<Funcionario> funcionarios = funcionarioController.findAllFuncionario();
    listaFuncionarios.clear();
    listaFuncionarios.addAll(funcionarios);
    tableFunc.setItems(listaFuncionarios);
}

private void handleFuncionarioClicado(Funcionario func) {
    if(func == null) {
        deleteBtn.setDisable(true);
        editBtn.setDisable(true);
    } else {
        deleteBtn.setDisable(false);
        editBtn.setDisable(false);
    }
}

the code of creating a query in db

public List<Funcionario> findAllFuncionario() {
    try {
        Session session = sessionFactory.getCurrentSession();
        session.beginTransaction();
        List<Funcionario> funcionarios = session.createQuery("from funcionarios").list();
        session.getTransaction().commit();
        return funcionarios;

    } catch (Exception e) {
        e.printStackTrace();
        return null;
    }

}

mainApp class

public void showFunc() {
    try {
        FXMLLoader loader = new FXMLLoader();
        loader.setLocation(MainApp.class.getResource("../view/Funcionarios.fxml"));
        AnchorPane funcScreen = (AnchorPane) loader.load();
        primaryStage.setTitle("EasySale - Funcionários");
        rootLayout.setCenter(funcScreen);
        FuncionarioViewController controller = loader.getController();
        controller.setMainApp(this);
        controller.setSessionFactory(sessionFactory);
        controller.addFunc();

    } catch (IOException e) {
        e.printStackTrace();
    }
}

And i'm getting these erros when i call showFunc()
