commons-vfs - Using FTPClient
I have the following code and I am attempting to get
a file stored locally, from an FTP site. The file exists
in the parent directory of the FTP site...
//CODE
String filename = "file.zip";
FTPClient f = new FTPClient();
f.connect("ftp.site.com")
f.login("loginname", "password");
System.out.println(f.getReplyString());
f.changeToParentDirectory();
f.type(FTPClient.BINARY_FILE_TYPE);
File file = new File("C:" + File.separator + "temp" + File.separator +
filename);
FileOutputStream fos = new FileOutputStream(file);
f.retrieveFile(filename, fos );
fos.close();
System.out.println(f.getReplyString());
f.logout();
System.out.println(f.getReplyString());
f.disconnect();
This is what the output displays.... message 425 takes about 20
seconds to display... Can anyone help me with this? Thanks!!!!
//OUTPUT
230 Login successful. Have fun.
425 Failed to establish connection.
221 Goodbye.

Great! The firewall was indeed the problem, since it could
not manage active sessions.
Thanks alot.

For me this is a problem with your (or the other side) firewall
configuration.
Sometimes a firewall do not support "active" ftp connections.
You can try to use f.enterLocalPassiveMode() (or so, sorry, I do not
remember the correct syntax yet).
This way commons-net will try to use passive ftp data connections which
might have more success bypassing a firewall.
But ... this has nothing to do with commons-vfs, do you try to use
commons-net through commons-vfs (using a ftp filesystem)?
Then there is a FtpFileSystemConfigBuilder which allows you to
setPassiveMode(opts, true).
If you need more support with this, just ask again.
Ciao,
Mario
