CDI + EL question

[pjiricka]

Hi,

the following example does not work for me (in GlassFish v3 - I was not successful at setting up JBoss 6 M1). I would like to ask whether it is supposed to work, and whether this is a bug either in Weld or in GlassFish.

I have the following interface:

@Named
@RequestScoped
public interface Bean extends Serializable {
   public String getName();
}

with the following implementation:

public class BeanImpl implements Bean, Serializable {
   public String getName() { return "x"; }
}

Now, I would expect that I can write #{bean.name} in JSF, and CDI will find the BeanImpl class and use it. However, in reality 'bean' is not found.

When I use the following in Java code:
public @Inject Bean mybean;

everything works fine. Also, when I delete BeanImpl and change Bean to a class, then #{bean.name}  works correctly.

Thanks,
Petr

@Named is not declared @Inherited, and even if it were, it would have no effect in this case, since @Inherited applies only to class inheritance and not to interface implementation.

And an interface is not a bean.

So you need to put the @Named (and also @RequestScoped) annotations on the bean, not on its interfaces.

Thanks for explaining, I see. Now I know how I can achieve what I wanted, the previous example should have been something like:

public interface Bean extends Serializable {
    public String getName();
}

public class BeanImpl implements Bean, Serializable {

    public String getName() { return "x"; }

    public static @Produces @Named("bean") Bean instance() {
        return new BeanImpl();
    };
}

Then I can write #{bean.name} in EL.
