About Question enthuware.oce-ejbd.v6.2.409 :

[lveto15]

I have doubts about this question and answer. According to specification (4.5.1):

@Asynchronous can be applied to a business method of a bean class OR to a method of a Local/Remote business interface.

annotation can be applied to a method of a business interface. But when I put it there and // NO CODE HERE on bean method answer is incorrect.

I have checked all combinations:
-- only on interface method
-- only on bean method
-- on both methods
and in all these cases my test is passed.

P.S.
Explanation doubt: shouldn't Thread.sleep be avoided (also according to specification):

The enterprise bean must not attempt to manage threads.

Not sure where you are looking but EJB 3.1 specification section 4.5.1 says:

@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) .

It doesn't talk about interface.

My mistake - the first position in google search is not final specification. I didn't pay attention to title . Thank you for pointing it .
