求救，通过RMI如何把远程的文件copy到本地，应该靠传递什么呢？？？

[hjw0571]

我用 FileInputStream传递，
老报错：
ava.rmi.UnmarshalException: error unmarshalling return; nested exception is:
java.io.WriteAbortedException: writing aborted; java.io.NotSerializableException: java.io.FileInputStream

implement Serializable

请问那个类，实现这个接口
是服务器，远程接口，还是客户端

[hjw0571]

public class HelloServer extends UnicastRemoteObject implements Hello,Serializable
public class HelloClient implements Serializable

我服务器，客户端 现在都加了，还是不行

不用这样传递文件吧？
用sock自己写吧：
发送：
out = new BufferedOutputStream(sock.getOutputStream());
in = new BufferedInputStream(sock.getInputStream());


fis = new FileInputStream(file);

byte[] b = new byte[5120];
for(int tmp=0;(tmp=fis.read(b))!=-1; )
{
out.write(b,0,tmp);
}
if(fis!=null)fis.close();
if(out!=null)out.close();
if(sock!=null)sock.close();

[zhmt]

sock = new Socket(addr, port);
fs = new BufferedOutputStream(new FileOutputStream(savePath));
out = new BufferedOutputStream(sock.getOutputStream());
in = new BufferedInputStream(sock.getInputStream());


System.out.println("start to recv....");
byte[] b = new byte[5120];
long recvSize = 0;
for (int tmp = -1; (tmp = in.read(b)) != -1;) {
fs.write(b, 0, tmp);
}

fs.close();
out.close();
in.close();
sock.close();

上面是发送
基本就这样子啊
