当我尝试使用apache commons ftpClient和以下代码上传简单的文本文件时：

imports*
public class ftpUpload {
public static void main(String[] args) {
    FTPClient ftp = new FTPClient();
    int reply;
    // connect
    try {
        ftp.connect(serverAdd);
        ftp.login(username,password);
        reply = ftp.getReplyCode();
        if(FTPReply.isPositiveCompletion(reply)){
            System.out.println("Connected Success..");
            // upload file
            try {
                String fileDir = "testfile.txt";
                FileInputStream in = null;       
                in = new FileInputStream(fileDir);     
                ftp.storeFile(fileDir,in);
                System.out.println("File upload complete..");
            }catch(IOException e){
                System.out.println(e);
            }
            ftp.disconnect();
            System.out.println("Disconnected..");
        }else {
            System.out.println("Connection Failed..");
            ftp.disconnect();
        }
    } catch (SocketException ex) {
        ex.printStackTrace();
    } catch (IOException ex) {
        ex.printStackTrace();
    }
  }
}
