我正在按照代码从书中的书中学习 rmi 进行练习，但 rmic 不起作用

public class NullPrinter extends UnicastRemoteObject implements Printer {
private PrintWriter log;
public NullPrinter(OutputStream log) throws RemoteException {
this.log = new PrintWriter(log);
}
@Override

// TODO Auto-generated method stub
return true;
}
@Override
public boolean printDocument(DocumentDescription document) throws RemoteException, PrinterException {
// TODO Auto-generated method stub
if (null == log) {
throw new NoLogException();
}
if (null == document) {
throw new NoDocumentException();
}
log.println("Printed file");
log.flush();
if(log.checkError()) {
throw new CantWriteToLogException();
}
return true;
}

留言：
警告：不推荐为 JRMP 生成和使用骨架和静态存根。骨架是不必要的，静态存根已被动态生成的存根取代。鼓励用户放弃使用 rmic 来生成骨架和静态存根。请参阅 java.rmi.server.UnicastRemoteObject 的文档。
错误：找不到类 printers.NullPrinter。1 个错误
但 nullprinter.class 在文件夹打印机中
