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 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?

5

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).

Muito Obrigado Adriano…

agora bora continuar os estudos…

ainda vou incomodar bastante.kkkkkk
