Tomcat 7, JSF 2.0 and @PostConstruct

Question

I have no idea what I'm doing wrong, please help:

1. Fresh Tomcat 7 with no extra jars in /lib folder
2. Simple web-app with mojarra 2.0.3 libs in WEB-INF/lib (jsf-api.jar, jsf-impl.jar)
3. Works fine except @PostConstruct in my beans - they're not called at all

Bean with unreachable method:

@ManagedBean
@ApplicationScoped
public class AppBean {

  @PostConstruct
  public void test() {
    throw new RuntimeException("test");
  }
}

That's all. Any ideas?

Answer 1

If your application scoped managed bean is not used on any pages, you have to annotate it with

@ManagedBean(eager=true)

in order to get it initialized on startup.

Answer 2

@PostConstruct应该在加载bean时工作，你可以在直接调用或使用eager = true时加载它，或者在构造函数中执行init。
