The explanation of the first answer says:

A method that is annotated with @Asynchronous must not throw any exception.

I think it should be:

A method that is annotated with @Asynchronous and returns void must not throw any exception.

Also, in last explanation:

All methods that are to be exposed in a business interface must be public. Also, a method that is annotated with @Asynchronous must not throw any exception.

it should be:

All methods that are to be exposed in a business interface must be public. Also, a method that is annotated with @Asynchronous and has return type void must not throw any exception.

You are right. Further, instead of exception, it should be application exception. The explanation has been updated.

thank you for your feedback!

Hi,
From last explanation:

All methods that are to be exposed in a business interface must be public

From Java SE Tutorial http://docs.oracle.com/javase/tutorial/ ... ceDef.html :

All methods declared in an interface are implicitly public, so the public modifier can be omitted

I thought business interfaces are just plain java interfaces, but maybe this is JEE specific behaviour that all methods must have public modifier?

Kind regards,
Jarek

Yes, the methods in the interface are public (no need for public modifier). But the code shown is a method with body, that means it is in a class and it must be public.
In this case, interface does not really refer to java interface definition but to the business interface presented by the bean.

HTH,
Paul.
