Oi Gabriel.

tem referenciar a ID da tabela de autores sem os dois pontos (:) pois vc está dentro do mesmo h:form

<p:commandButton value="Gravar" action="#{autorBean.gravar}"
                        process="@form" update="@form formtabelaAutores" />

Oi Gabriel,

através desse exceção a única coisa que a gente sabe que deu NullPointerException. Infelizmente não ajudou :(

Tente voltar para uma versão do xhtml que funciona, depois coloque em pequenos passo (sempre testando) as alterações novamente para isolar o problema e descobrir o que deu errado.

Esqueci de falar: Existente em cada capitulo, no inicio da explicação, um download com o projeto e codigo do capitulo anterior. talvez valha a penas pegar esse download para comparar com o seu autor.xhtml.

Essa é mais fácil :) O usuário/senha do banco de dados está errado.

Dá uma olhada no persistence.xml (na pasta src/META-INF).

O problema é o que o Nico disse mesmo. Gabriel, você chegou a ler a resposta dele?

O usuário e senha do banco estão errados. Se você mudou o usuário e senha e não lembra.... bem.. tem que lembrar né.

Dê uma olhada em peristence.xml que fica na pasta src/META-INF.

Não vejo outro motivo que não seja esse.

Aguardo seu feedback.
