Question

我试图在java web start aplication中使用Apache FTPCleint连接到FTP服务器。以下是我正在使用的代码。

ftpInstance = new FTPClient();

ftpInstance.setRemoteVerificationEnabled(false);

ftpInstance.connect(<HostName>);
int rpyCode = ftpInstance.getReplyCode();

if(!FTPReply.isPositiveCompletion(rpyCode)){
    throw new Exception("Connection Rejected with reply code " + rpyCode + ". - " + <Hostname>);
}

问题出在ftpInstance.connect(<HostName>)行。抛出异常请查看堆栈跟踪

上面的代码在普通项目中工作正常，但在java web start中没有。

感谢任何帮助。感谢。

您已配置SOCKS代理设置，指向不属于SOCKS代理的内容。

java.net.SocketException：来自SOCKS服务器的错误回复，使用apache FTPClient
