的Java找不到.class文件，或

Question

类

我有这样的目录结构：

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

我当前的工作目录是project/src/，我用命令java -cp "../bin/" videoserver.Main

这没事我看来， ，但Java告诉我它找不到类IVideoServer。我可以在正确的文件夹中看到IVideoServer.class，并且它似乎能够很好地找到Main类。

什么可能导致Java无法找到IVideoServer？

，似乎是导致该问题的方法是这样的一个

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(); 
    } 
} 

我已经编译了一个所有参与javac类的。

从src文件夹中，你试过java -cp . videoserver.Main ??

试试这个，javap videoserver.Main
