What is an Application Scoped Bean? I understand it to be a bean which will exist for the life of the application, but that doesn't appear to be the correct interpretation. I have an application which creates an application scoped bean on startup (eager=true) and then a session bean that tries to access the application scoped bean's objects (which are also application scoped). But when I try to access the application scoped bean from the session scoped bean, I get a
null pointer exception. Here's excerpts from my code:
Application Scoped Bean:
@ManagedBean(eager=true)
@ApplicationScoped
public class Bean1 implements Serializable{
private static final long serialVersionUID = 12345L;
protected ArrayList<App> apps;
// construct apps so they are available for the session scoped bean
// do time consuming stuff...
// getters + setters
Session Scoped Bean:
@ManagedBean
@SessionScoped
public class Bean2 implements Serializable{
private static final long serialVersionUID = 123L;
@Inject
private Bean1 bean1;
private ArrayList<App> apps = bean1.getApps(); //
null pointer exception
What appears to be happening is, Bean1 is created, does it's stuff, then is destroyed before Bean2 can access it. I was hoping using application scoped would keep Bean1 around until the container was shutdown, or the application was killed, but this doesn't appear to be the case.
