Novo Autor

Dados do Autor

AutorBeanjava package br.com.caelum.livraria.bean;

import javax.faces.bean.ManagedBean;

import br.com.caelum.livraria.dao.DAO; import br.com.caelum.livraria.modelo.Autor;

@ManagedBean public class AutorBean {

private Autor autor = new Autor();

public Autor getAutor() { return autor; }

public void gravar() { System.out.println("Gravando autor " + this.autor.getNome());

new DAO(Autor.class).adiciona(this.autor); } }

De qualquer maneira vou postar o código aqui que tenho desse projeto e está funcionando:

autor.xhtml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
    xmlns:h="http://java.sun.com/jsf/html">

<h:body>
    <h1>Novo Autor</h1>
    <h:form>
        <fieldset>
            <legend>Dados do Autor</legend>
            <h:panelGrid columns="2">
                <h:outputLabel value="Nome:" for="nome" />
                <h:inputText id="nome" value="#{autorBean.autor.nome}" />
                <h:commandButton value="Gravar" action="#{autorBean.gravar}" />
            </h:panelGrid>
        </fieldset>
    </h:form>
</h:body>

</html>

AutorBean

package br.com.caelum.livraria.bean;

import javax.faces.bean.ManagedBean;

import br.com.caelum.livraria.dao.DAO;
import br.com.caelum.livraria.modelo.Autor;
import br.com.caelum.livraria.util.RedirectView;

@ManagedBean
public class AutorBean {

    private Autor autor = new Autor();

    public Autor getAutor() {
        return autor;
    }

    public RedirectView gravar() {
        System.out.println("Gravando autor " + this.autor.getNome());
        new DAO<Autor>(Autor.class).adiciona(this.autor);
        this.autor = new Autor();

        return new RedirectView("livro");
    }

Colei o seu código no meu projeto e não houve erro, estou suspeitando que seja algum problema em relação ao banco de dados, o erro parece muito com esse relatado aqui: https://cursos.alura.com.br/forum/topico-java-lang-exceptionininitializererror-29692

Vc conseguiria postar a stacktrace completa do erro?

Bom dia, Tiago

O Servidor Start sem erros, o problema ocorre quando chamo no navegador "http://localhost:8080/livraria/autor.xhtml" e peço para gravar o nome do autor. Substituir no persistence.xml de org.hibernate.ejb.HibernatePersistence para org.hibernate.jpa.HibernatePersistenceProvider, mas continua o mesmo erro. Segue o erro que aparece no navegado ao tentar gravar o auto:
