java.net.SocketException：来自SOCKS服务器的格式错误的回复，使用apache FTPClient

问题描述

我正尝试在Java web start应用程序中使用Apache FTPCleint连接到FTP服务器。
下面是我使用的代码。

  ftpInstance = new FTPClient（）; 
 
 ftpInstance.setRemoteVerificationEnabled（false）; 
 
 ftpInstance.connect（< HostName>）; 
 int rpyCode = ftpInstance.getReplyCode（）; 
 
 if（！FTPReply.isPositiveCompletion（rpyCode））{
抛出新异常（Connection Rejected with reply code+ rpyCode +。 - +< Hostname>）; 
} 
  

问题出现在 ftpInstance.connect（<主机名>）。抛出异常请看堆栈跟踪

以上代码在正常项目中工作正常，但不在java web start中。

您已配置指向非SOCKS代理的SOCKS代理设置。 / p>

Above code is working fine in normal project but not in java web start.

Any help is appreciated.Thanks.

You have configured SOCKS proxy settings that point to something that isn't a SOCKS proxy.
