well, I have solved(hope so) it myself, I just don't use the bat file to run the RMI server program and just run the rmiregistry and java command in two different windows and then it does give me no exception. But haven't tested with client program, so not sure whether can work with client correctly or not.
But any way, I think maggri does put in effort, so thanks a lot
