我有这段RMI代码而且我不知道它为什么找不到IAuthentication类。该类存在于包中。
String name = "//" + args[0] + ":" + args[1] + "/" + args[2];
try {
ApplicationService appService = new ApplicationService();
IAuthentication MainServer = new Authentication(appService);
Naming.rebind(name, MainServer);
System.out.println("- ServiceFacade '" + name + "' active and waiting...");
} catch (Exception e) {
System.err.println("$ ServiceFacade exception: " + e.getMessage());
e.printStackTrace();
}
这就是我得到的：

java.lang.ClassNotFoundException: es.deusto.ingenieria.sd.authentication.server.remote.IAuthentication
