Estou desenvolvendo uma aplicação com GWT e JPA provider EclipseLink.
Quando executo a aplicação no Run as > Java Application como teste ela funciona normal, mas
quando executo a aplicação no Run as > Web Application a seguinte exceção é lançada:

A exceção diz que a fabrica não está encontrando o PersistenceUnit mas eu já conferir e está tudo declarado no Persistence.xml
Criei um método main() só pra teste no lado do servidor e tudo funciona normal quando executo como Java Application (é realizado o cadastro no BD),
mas quando executo como Web Application… da pau!
Pessoal, mudei a versão do eclipselink e a exceção lançada mudou para a seguinte:

Quando executo como uma app java se roda normal, mas quando executo como uma web app a exceção acima é lançada quando tento persistir um objeto.
a principio eu estava pensando que fosse pq eu criei algumas classes num sub pacote do servidor tipo:
