Ant FTP任务失败：java.net.SocketException

我正在尝试使用Ant，通过FTP将zip文件上载到Windows Server 2008 R2 FTP服务器（如果有必要的话）。我有一个类似的任务来创建目录/发布，它可以工作，但是通过FTP上传给我带来了一些问题

    <ftp    action="put"
            userid="${adapter.ftp.username}" 
            password="${adapter.ftp.password}"
            server="${ftp.hostname}"
            retriesAllowed="5"
            verbose="true"
            systemTypeKey="WINDOWS"
            remotedir="/Release" >

        <fileset dir=".">
            <include name="Adapter.zip"/>
        </fileset>
    </ftp>

我做错了什么？

关闭Windows防火墙解决了问题。

一件值得尝试的事情是被动ftp。蚂蚁对此有一个

被动
属性：

选择被动模式（“是”）传输，以便更好地通过防火墙
以性能为代价的连接性。默认为“否”

有一篇关于主动模式和被动模式区别的文章。关键的一点是，对于ftp命令（包括在OP问题中工作的mkdir和chdir），使用一个打开的端口——通常是端口21。但对于数据传输，使用了另一个可能是防火墙阻止的端口。ftp与防火墙相关的问题有时会出现上述症状。
我也有同样的问题，但无法关闭防火墙，因为我不是管理员。还有其他解决方案吗？注意：使用另一个ftp客户端，如filezilla，效果很好！谢谢虽然没有帮助，但被动=“是”仍然存在同样的错误。但也许我们的思路是对的，因为像list和mkdir这样的命令工作得很好。只是发送和放置失败。
