Question

我有一个目录结构：

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

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

这对我来说似乎都是正确的，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，它似乎能够很好地找到Main类。

什么可能导致Java无法找到IVideoServer？

似乎导致问题的方法就是这个

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javac所涉及的所有类。

这是返回给我的完整异常和堆栈跟踪

从src文件夹中，您是否尝试过java -cp . videoserver.Main ??

试试这个，javap videoserver.Main

Java无法找到.class文件或类
