The way IDEA presents an option for the interface the bean method should be
declared in when the intentions pop-up (local/remote or business interface)
is great. However, one would have to manually create the business interface
and make the remote one extend it (and the bean class implement it) before
getting this functionality, since there is no option for using the business
interface pattern when the EJB is created.
You might want to add the business interface to the EJB Names pane and a
check-box to the Create Bean dialog (and create the interface accordingly)
before declaring the support for this pattern complete.
This might be planned already, I just thought I'd mention it (since I don't
recall seeing it discussed).
