CDI-JSF: Use @Inject to annotate a field of a bean

Most commonly, JSF applications uses dependency injection by annotating private fields with @Inject. We can inject directly an instance of another class (bean) or we can inject an javax.enterprise.inject.Instance and use the get() method to obtain the needed instance:

public class TheBean {

 private static final Logger LOG = Logger.getLogger(TheBean.class.getName());

 private Foo foo;
 //private Instance<Foo> foo;
 private Buzz buzz;
 //private Instance<Buzz> buzz;
 private Bizz bizz;   
 //private Instance<Bizz> bizz;

 public void callFooBuzzBizz() {"TheBean#callFooBuzzBizz() called ...");
  Messages.addGlobalInfo("TheBean#callFooBuzzBizz() called ...");
  // foo.get().fooify();
  // buzz.get().buzzify();
  // bizz.get().bizzify();

The complete example is available here.
