@Inject session bean into war

[klind]

JBoss 7.1.1-final

I have a Simple session bean in the EJB module, and inject this session bean in a class in the war module.

But I get a NullPointerException when runnig the code... injection is not working..

I got a setup that is very similar to this where it works, and I can't seem to find any differences on how the injection is done..

I do not use the injected sessionbean in the constructor.

@Stateless(name = "HibernateUtilsSBBean", mappedName = "jsi/ejb/HibernateUtilsSBBean")
public class HibernateUtilsSBBean implements HibernateUtilsSBBeanLocal, HibernateUtilsSBBeanRemote {
     ......
}

@Local
public interface HibernateUtilsSBBeanLocal {
....
}

@Remote
public interface HibernateUtilsSBBeanRemote {
...
}

pojo class in the web app that @Inject sessionbean. 

@Inject
    private HibernateUtilsSBBeanLocal hibernateUtils;

Maven project.. 
EAR
     - WAR
          - WEB-INF
               beans.xml
               classes
                    com.foo.... class that @Inject sesison bean interface
     - EJB
          - META-INF
               beans.xml
     - META-INF
          beans.xml
          com.foo.... session bean class
     lib

That's a bit strange since usually the CDI implementation complains about injections points it can't fulfill. The only case where this usually happens when the instance doesn't come from the container (e.g. you have used new()), in which case injection can't occur.

How does the object of the "pojo class in the web app that @Inject sessionbean" get created?

Injection only happens if the container creates the object for you.

This is an existing project where I slowly wanna implement injections, and you guys are right.

The pojo is created with the new operator.

So I guess I have to use @injection all the way... starting from the servlet ??

Yep, @Inject (or @EJB) is the way to go.
