Well, you would need to follow the protocol conversations. But maybe
just try the debugging first.
cheers

Hi!
I think your only chance is to use tcpdump and/or wireshark to
debug the
network flow to see the real answers of the ftp server.
Or debug into the VFS code ... somewhere in doAttach in FtpFileObject
and see whats going wrong in there.
Sorry!
Ciao,

Well, I ran it once and it said "The file type is file" and it
succeeded, but then I ran it again and it says "The file type is
imaginary" and it failed. Here's the code:
final FileSystemManager fsm = VFS.getManager();
final FileObject remoteFile =
fsm.resolveFile("ftp://ftp.ncbi.nih.gov/pub/HomoloGene/current/
homologene.data");
System.out.println("The file type is " +
remoteFile.getType().getName() + ".");
final File tmp = File.createTempFile("download", ".txt");
tmp.deleteOnExit();
final FileObject tempFile = fsm.toFileObject(tmp);
FileUtil.copyContent(remoteFile, tempFile);
Here's the complete output:

I left out the project-specific parts of the stack trace because
it's
not relevant, but there were no nested exceptions.

Hi!
Did you get my second email? That's the entire output I got
when I ran it.
Uh, oh, ok!
So then, it seems that VFS thinks the file is either a directory
or non
existent.
Could you please:
*) check the filetype of the FileObject see if its virtual or
whatever
*) try to connect to the ftp server using a commandline tool to
see if
the ftp output is in a style which makes it impossible for
commons-net
to parse the output, e.g. due to localized date format.
Ciao,
Mario
