问题描述

我正在尝试使用 XAMPP 和 FileZilla 通过 FTP 上传一个简单的 txt 文件.
我正在使用 Apache Commons Net 3.0.1 库.
这是我的代码，非常基本的东西:

I'm trying to upload a simple txt file via FTP using XAMPP and FileZilla.
I'm using the Apache Commons Net 3.0.1 Library.
This is my code, very basic things:

FTPClient client = new FTPClient();
InputStream in = new ByteArrayInputStream("IT WORKS! :D".getBytes());

try {
    client.connect("localhost");
    client.login("user", "password");
    client.enterLocalPassiveMode();
    client.storeFile("textfile.txt", in);
} finally {
    try {
        in.close();
        client.logout();
        client.disconnect();
    } catch (Exception e) {
    }
}

但是... storeFile() 抛出 java.net.SocketException:

But... storeFile() throws a java.net.SocketException:

有什么问题??:(我还尝试了在线托管服务，结果相同...
请问这是防火墙还是windows服务相关的问题??

What's the problem?? :( I tried also on an online hosting service, with the same result...
I wonder if this is a firewall or windows' services related problem??

推荐答案

通过在命令提示符下以管理员身份运行解决:

netsh advfirewall set global StatefulFTP disable

这是 Windows 机器上的 Java 7 错误，报告 这里.

This is a Java 7 bug on Windows machines, it is reported here.
