Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I need some help on this issue. First question. I've searched many pages but found no solution for my problem. I guess my code needs to use Active mode when connecting an FTP server. I've tested access to the FTP server through filezilla (only works with active mode data connection) and windows explorer and it works on my pc but doesn't work on my deployed server.

ftpClient.enterRemoteActiveMode(?)

I also need some help with this method of commons net api. thanks.
