I'm in the process of porting (well, re-creating really) a web app with Seam.
It's been working great except that I get an Exception when using @EJB to
inject another session bean.
Until now, all my session beans had worked independantly of each other so I
hadn't noticed this.
I have a session bean:
@Stateful
@Name("showMatrix")
@Scope(ScopeType.SESSION)
public class PlayerActionBean implements PlayerActionLocal {
@In(create=true)
private EntityManager entityManagerSeam;
@In(required=false)
PlayerPlay selectedPlayerPlay;
@Out(required=false)
List someList;
@EJB
private SomeBeanLocal someBean;
@Factory("someList")
public void create() {
// use someBean here
}
...
}
This worked fine until I tried injecting a session bean "someBean" with @EJB.
Any ideas what could be going wrong?
