的Java找不到.class文件，或

類

project/ 
     src/ 
      videoserver/ 
        *.java 
      storeclient/ 
        *.java 
     bin/ 
      videoserver/ 
        *.class 
      storeclient/ 
        *.class

我當前的工作目錄是project/src/，我用命令java -cp "../bin/" videoserver.Main

這沒事我看來，，但Java告訴我它找不到類IVideoServer。我可以在正確的文件夾中看到IVideoServer.class，並且它似乎能夠很好地找到Main類。

什麼可能導致Java無法找到IVideoServer？

，似乎是導致該問題的方法是這樣的一個

public static void main(String[] args) 
{ 
    try 
    { 
     VideoServer Server = new VideoServer(); 
     videoserver.IVideoServer stub = (IVideoServer)UnicastRemoteObject.exportObject(Server, 0); 

     // Bind the remote object's stub in the registry 
     Registry registry = LocateRegistry.getRegistry("server-url", 9090); 
     registry.bind("VideoServer", stub); 
     System.err.println("Server ready"); 
    } 
    catch (Exception e) 
    { 
     System.err.println("Server exception: " + e.toString()); 
     e.printStackTrace(); 
    } 
}

我已經編譯了一個所有參與javac類的。

這是一個完整的異常和堆棧跟蹤，因爲它返回到我
