Estou tentando ao máximo fazer a atividade bem parecida com o da aula. Acho que só a versão do meu Eclipse que é diferente e a versão do VRaptor eu acho. E toda vez surge um erro diferente na mesma parte: Importar a Lista. Alguém consegue me ajudar??

HTTP Status 500 - net.vidageek.mirror.exception.ReflectionProviderException: Could not invoke method lista

type Exception report

Ele está informando que não existe um persistence-unit configurado no seu persistence.xml com o nome default.

Esse é o meu Entity Manager Producer

package br.unemat.digera.infra;

import javax.enterprise.context.ApplicationScoped;
import javax.enterprise.context.RequestScoped;
import javax.enterprise.inject.Disposes;
import javax.enterprise.inject.Produces;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;

@ApplicationScoped
public class EntityManagerProducer {

    private EntityManagerFactory factory = Persistence.createEntityManagerFactory("default");

    @Produces
    @RequestScoped
    public EntityManager getEntityManager(){
        return factory.createEntityManager();
    }

    public void close(@Disposes EntityManager manager){
        manager.close();
    }

}

E esse o meu Persistence

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

             <property name="hibernate.hbm2ddl.auto" value="update"/>
             <property name="hibernate.show_sql" value="true"/>
             <property name="hibernate.format_sql" value="true"/>
         </properties>

     </persistence-unit>

</persistence>

Se preciso for, envio todo o meu projeto. Pq não sei mais o que estou errando :/

Se puder, peço que por favor veja o que há de errado com meu sistema. Não consigo ver porquê não está achando a conexão. https://www.dropbox.com/s/ep0wfq1xqyji0i5/Digera.rar?dl=0

A versão do hibernate é a 5? Se for, apaga a linha de configuração do provider :(. O provider mudou nessa versão e o antigo ta quebrado. Não cheguei a ver o link da dropbox.
