Bom dia pessoal,
eu recebi um projeto já desenvolvido e coloquei dentro do meu eclipse,
porém estou tendo um probleminha.
ele da o seguinte erro:
javax.persistence.PersistenceException: No Persistence provider for EntityManager named conexao

Porém eu tenho minha classe de persistence.xml dentro da pasta META-INF do meu projeto,

Alguém saberia me explicar o porquê que está dando este erro ?
