Why only stub and not both stub and skeleton is made when i enter the command rmic MyRemoteImpl?

Here MyRemoteImpl.java is the file containing methods that will run at server side.I used same computer as client and server.When i entered rmic MyRemoteImpl then only MyRemoteImpl_Stub.class was formed and MyRemoteImpl_Skel.class was not formed.The book in which i studied this concept is Head First Java.Ubuntu is OS on which i am running the command.
