Femi,
Since JDK 1.2 -- and according to the RMI specification -- the "Skeleton" is not required (if both client and server are at least JDK 1.2). I guess that with JDK 5.0, they finally decided that it is now all right to completely discard the "Skeleton", and have "rmic" create a "Stub" only.
From the (lack of) information you have provided, it looks like your client is some kind of GUI application, and you are trying to communicate directly with the remote object. In case you are unaware, the RMI client _must_ interact only with the remote interface (not the remote object).
For your information, Dr Richard Baldwin has a series of "lessons" (as he calls them) on RMI -- that I found very useful when I was learning RMI:
http://www.dickbaldwin.com/tocadv.htm Lesson 600 is the first in the series.
Good Luck,
Avi.
