Does anybody know what I can do about a java.net.SocketTimeoutException when I'm calling the FTPClient.put method? It's happening pretty consistently with some of my clients, and my hosting service claims that the problem isn't on their end. Thanks,

Jay

Possibly a problem with your firewall. Try switching between transfer modes (active and passive) and also test with ftp.exe.
