Accessing persist method in SLSB from my SFSB

Hello,

I have an issue with an order i try to persist. I use Hibernate 4 with JPA and Jboss 7.1. I have a shopping cart which is a SFSB :


In the executeSale method I'm using methods from my SLSB DAO (I'm only going to display the first one which is where it fails since it's first) :




The error occurs line "entityManager.persist(transientInstance);" with a NPE. See the full stacktrace here. I checked on debug and my Commande object isn't null, so I guess it's coming from my Persistence Context, but I don't know what the problem is exactly. Any help is appreciated. Thanks.


EDIT : Nevermind, just forgot some annotations like another @EJB and @PersistenceContext...
 
It is sorta covered in the JavaRanch Style Guide.
