Java Apache FTP：可以连接但无法上传

Question

我在JAVA中使用此代码

    FTPClient client = new FTPClient();
    FileInputStream fis = null;

    try 
    {
        client.connect("ftp.serverapp.amon-internet.com");
        client.login("u780746385", "serverapp");
        //client.changeWorkingDirectory("/");
        //client.setFileType(org.apache.commons.net.ftp.FTP.ASCII_FILE_TYPE); 
        //client.enterLocalPassiveMode();

        //
        // Create an InputStream of the file to be uploaded
        //
        String filename = "test.txt";
        fis = new FileInputStream(filename);

        //
        // Store file to server
        //
        client.storeFile(filename, fis);
        client.logout();
    } 
    catch (IOException e) 
    {
        e.printStackTrace();
    } 
    finally 
    {
        try 
        {
            if (fis != null) 
            {
                fis.close();
            }

            client.disconnect();
        } 
        catch (IOException e) 
        {
            e.printStackTrace();
        }
    }

所以它可以连接，但是当它试图上传我的文件时，它会说：

我只想说，使用C＃中的Microsoft librairie，它可以使用相同的FTP服务器。

你知道为什么它在JAVA中不起作用吗？

谢谢：）

编辑：我终于找到了问题。 Windows的防火墙阻止Java访问FTP服务器，每次我的应用程序运行时，我都会使用此代码进行异常

Process p = Runtime.getRuntime().exec("netsh advfirewall set global StatefulFTP disable");
        p.waitFor();
        BufferedReader reader = new BufferedReader(
                new InputStreamReader(p.getInputStream()));
        String line = reader.readLine();
        while (line != null) 
        {
             line = reader.readLine();
        }
