Howdy!

I'm not sure if it asks the appropriate question.

Where all can you place @Asynchronous annotation to make a method asynchronous?

By saying that, i.e., this answer is incorrect:

at method level in the bean class as well as in the business interface.

Aren't you saying that I am not able to annotate @Asynchronous method in the interface only? Or in the interface AND bean?

Then again, if I can, maybe the question should be rephrased to something indicating that it asks for the minimal requirement of @Asynchronous annotating?

Thanks in advance!

Cheers!

I think the question statement should change from can to must, "Where all must you place @Asynchronous annotation to make a method asynchronous?"

Hi!

I thought that we could put any @ at bean (class or method, it depends) or at the interface. The explanation says

There is no need to put @Asynchronous annotation in the interface anywhere.

Does this mean we can´t put this @ at the interface? Or we can but there's no need? The question says "Can".

Thanks!

You can put it at interface also. But you don't need to put it in both the places i.e. in interface as well in class.
HTH,

Looks like I'm not the only one with issues with this question

Hi Paul,
Based on your explanation, the last option is also correct :

at method level or class level either in the bean class or in the business interface, but not in both (the class and the interface.)

However, based on the specification 4.5.1,

@Asynchronous can be applied to a particular business method of a bean class (or superclass) or at the class level of a bean-class (or superclass). If @Asynchronous is applied at the class level....

I don't see any documentation saying @Asynchronous can be applied to any business interface.

You are right. Putting it in interface doesn't look valid.
thank you for your feedback!
