RE: I got NullPointer Exception when I test my ejb (EJB3.0 version) using Junit with Cactus

Hi, Franz

In the new version EJB3.0 we use annotation @EJB to refer an ejb

@EJB
SampleFacadeLocal sampleFacade;

We don't use instance. Even though I instantiated it, I got Null Pointer
in SampleFacade class at line that use em(EntityManager). In EJB3.0 we
define em like this:

@PersistenceContext(unitName="someName")
private EntityManager em;

Thanks.

hi,

in your sample-code the sampleFacede is never instantiated; so it's null

while you're trying to find somthing with it?!
