请高手赐教！版主帮我顶啊！谢谢！
本段程序是实现按照本地机器上的一个文件夹目录结构传送到ＦＴＰ服务器上的功能，为了简化方便高手的解答我只传送一层，多层跟这个一样的问题！下面程序中一个是判断文件和文件夹的，两个相互分开时，可以运行，但放在一起会出错！
错误信息：
java.io.FileNotFoundException: CWD /2: 550 /2/???¨??????: Failed to create.

你只需要提供最上层的目录路径就可以了，也就是替换我的程序中初始化类中的File f=new File( "d:\\temp ");参数即可
import java.io.File;

public class test2 {
public test2() {
File f=new File( "d:\\temp ");
String path=f.getAbsolutePath();
String list[]=f.list();

for (int i=0;i <list.length;i++)
{
File f2=new File(path+ "\\ "+list[i]);

if (f2.isDirectory()==true)
{
this.showlist(path+ "\\ "+list[i]);
}
else
{
System.out.println(path+ "\\ "+list[i]);
}
}
}

public void showlist(String path){
File f3=new File(path);
String path2=f3.getAbsolutePath();
String list2[]=f3.list();

for(int j=0;j <list2.length;j++)
{
File ff=new File(path2+ "\\ "+list2[j]);
if(ff.isDirectory()==true)
{
this.showlist(path+ "\\ "+list2[j]);
}
else
{
System.out.println(path2+ "\\ "+list2[j]);
}
}
}

public static void main(String[] args) {
test2 test21 = new test2();
}
}

来领分呵呵
===
在ftpclient.sendServer( "XMKD " + pathafter + "\r\n ");之后加上这句：
ftpclient.readServerResponse();
------解决方案--------------------
