Boa noite!

Após importar o vraptor-jpa e o simplemail, apaguei os arquivos como diz no exercício. No entanto, quando subi o servidor, está dando esse erro:

Abandonei o maven e importei o .jar. Quando excluí o EntityManagerProducer deu esses dois erros:

GRAVE: Exception sending context initialized event to listener instance of class org.jboss.weld.environment.servlet.Listener
org.jboss.weld.exceptions.DeploymentException: Exception List with 3 exceptions:
Exception 0 :

e

Depois de muito ler descobri que esse erro aí de cima é por causa da versão do vraptor-jpa. Corrigi e agora está dando esse erro:

Consegui resolver. O problema era que o vRaptor subia, a JPAUtils executava, e eu tinha colocado o EM por injeção. Tirei a injeção e criei ela na mão.
