That’s how you’ll come, nothing shows up. My web project is correctly configured for Vraptor, but I think the problem is in these two files below;

Product and the Product Controller

package br.com.fj28.dao;

import java.util.List;

import org.hibernate.Session;
import org.hibernate.Transaction;

import br.com.caelum.vraptor.ioc.Component;
import br.com.fj28.infra.CriadorDeSession;
import br.com.fj28.modelo.Produto;

@Component
public class ProdutoDao {

    private final Session session;

    public ProdutoDao() {
        this.session = CriadorDeSession.getSession();
    }

    public void salva(Produto produto) {

        Transaction tx = session.beginTransaction();
        session.save(produto);
        tx.commit();
    }


    public List<Produto> listaTudo(){
        return this.session.createCriteria(Produto.class).list();
    }

}

///////////////////////////////////////////////////////

package br.com.fj28.controller;

import java.util.List;

import br.com.caelum.vraptor.Resource;
import br.com.fj28.dao.ProdutoDao;
import br.com.fj28.modelo.Produto;

@Resource
public class ProdutosController {

    private final ProdutoDao dao;

    public ProdutosController(ProdutoDao dao){
        this.dao = dao;

    }

    public List<Produto> lista(){
        return dao.listaTudo();
    }

}

could someone give me a suggestion to solve the problem?

I am confirming that there are records in the Mysql database.

Apparently you forgot to import the JSTL tag lib this way:

<%@ taglib prefix="c"% uri="http://java.sun.com/jsp/jstl/core">
<%@ taglib prefix="fmt"% uri="http://java.sun.com/jsp/jstl/fmt">

PSC: fmt -> if you need formatting
