无法在FTP服务器上创建目录

Question

我正在尝试使用FTPServer Apache构建嵌入java的FTP服务器/客户端。 登录到服务器后，我需要在服务器上创建一个目录，以便开始上传（或者这就是我理解我至少应该做的事情）。到目前为止，服务器端运行良好。 但它似乎没有用。你能看到我忽略的东西吗？ 谢谢

客户的代码：

            package client;
            import java.io.File;
            import java.io.FileInputStream;
            import java.io.IOException;

            import org.apache.commons.net.ftp.FTP;
            import org.apache.commons.net.ftp.FTPClient;
            import org.apache.commons.net.ftp.FTPFile;
            import org.apache.commons.net.ftp.FTPReply;
            import org.apache.commons.net.ftp.FTPConnectionClosedException;

             class ftp{
             public static void main(String[] args) throws IOException {
            FTPClient client = new FTPClient();
            FileInputStream fis = null;
            boolean result;
                            String ftpServerAddress="192.168.171.133";
                            String userName="iman";
                            String password="iman";

            try {
                    client.connect(ftpServerAddress, 1959);
                    result = client.login(userName, password);

                    if (result == true) {
                            System.out.println("Successfully logged in!");
                    } else {
                            System.out.println("Login Fail!");
                            return;
                    }

                    //Changing the working directory

                    result=client.makeDirectory("/home/Serveur/workspac");

                    if(result==true){
                            System.out.println("New Directory is created on Ftp      Server!");
                    }
                    else{
                            System.out.println("Unable to create new directory!");
                    }

                                            client.setFileType(FTP.BINARY_FILE_TYPE);


                    File file = new File("/home/client/workspace/Client/dos");
                    String testName = file.getName();
                    fis = new FileInputStream(file);
                    int c= client.getReplyCode();
                    System.out.println(c);

                    // Upload file to the ftp server
                    result = client.storeFile(testName, fis);
                   //result= client.remoteStore(testName);


                    if (result == true) {
                            System.out.println("File is uploaded successfully");
                    } else {
                            System.out.println("File uploading failed");
                    }
                    client.logout();
            } catch (FTPConnectionClosedException e) {
                    e.printStackTrace();
            } finally {
                    try {
                            client.disconnect();
                    } catch (FTPConnectionClosedException e) {
                            System.out.println(e);
                    }
            }
    }
  }

输出如下：

Successfully logged in!

Unable to create new directory!

200

File uploading failed
