Olá pessoal,

Estou iniciando no mundo Java agora, e comprei um livro citado acima para iniciar. comecei a seguir os passos do livro chegando na parte do cadastraAutomoveis.xhtml, incluir um automovel no banco. Quando tento executar o codigo no eclipse aparece a seguinte mensagem.

Poderiam me ajudar?

Oi @tiago.tarinfo1, parece que só faltou adicionar a JTA no classpath.

Veja se o .jar dela está nas dependencias do Hibernate (não me lembro de cabeça se já vem junto). Se não tiver, você pode baixá-lo lá no repositório do maven: [http://mvnrepository.com/artifact/javax.transaction/jta/1.1](http://mvnrepository.com/artifact/javax.transaction/jta/1.1) e depois adicionar no classpath manualmente.

Isso deverá resolver o problema.

Pessoal… funcionando…

para funcionar tirei a pasta META-INF (que continha o meu persistence.xml) da pasta WebContent(criada automaticamente quando gerei o projeto) e coloquei dentro da pasta SRC… dai funcionou.

Alguém poderia me explicar por que?

Boa @tiago.tarinfo1, parabéns.

O que acontece é que a pasta META-INF dentro do WebContent não faz parte do Classpath, então na hora que o aplicativo sobe pro servidor, a JPA procura o persistence.xml dentro do META-INF, mas não encontrava.

Já o que está no src faz parte do Classpath (na verdade, tudo que está dentro do src faz parte dele).
