Passing Interface as an EJB parameter?

2002-01-08 Thread Keith Kee 

Hi:
  Is it legal to pass an interface like List as a parameter to a remote
interface of an EJB? Conversely, how about returning an interace like List
as the return type? Since List is an interface and not serializable, I
wonder if it would be marshalled/unmarshalled correctly.

Thanks,
keith

Legally You can declare return types any Interface though the interface may
not be extending from Serializable.
The marshalling and UnMarshalling happens on the object at runtime the
object which you are returning must be serializable.

Yes, you can pass the Interface.  The underlying object must be serializable, however. 
 Personally, I use ArrayList in this scenario.
