The one of the must conditions is the original interface should not be altered. You can extend the interface and throw your own exceptions and rmi exceptions.

Simply... No. I mean if you add custom exceptions then you are now programming to an implementation rather than an interface (if you are confused or unsure or never ehard that OO principle, I can suggest Head First Design Patterns).
