I'm freaking out now! I can not find out why it fails to retrieve the PersistenceUnit. The worst thing is that when I run the EJB project profile tests, the "config-arquillian-glasfish", it runs perfectly, but when I run the complete project profile default, gives this error.
I've tried everything and apparently everything is configured correctly. The project is attached for those who want to try ... Please help me! Thank you. (Sorry for my english, I'm Brazilian)
