Hi Ruud,
Local vs Remote interfaces?.....mmm...
The methods in your ejb's are reusable or may become reusable by another application in the future? if that's the case then
you should implement remote interface.
But if the methods in your ejb's are only used by your webmodule then you should implement local interface so you can get better performance.
I see no complication by implementing local & remote interfaces, that way you could use local interfaces for now, and when the time comes for an application to use your ejb's methods, they could get them using the already implemented remote interface.
Consider the fact that remote interface is more expensive in performance that local interface.
