The fresh step 1.dos JRMP stub protocol performed out to your dependence on skeletons. It appears to be for me the Proxy classification produced for the Coffees 1.step 3 you may change RMI stubs. I don’t know why so it has never happened but really — probably I am forgotten something. It might be sweet to use RMI in the place of bothering having rmic no matter if. – Peter
