Seems I had something similar and I couldn't get it as well before since I
always was getting UrlFileProvider. After I looked on the code I see that
providers.xml contains
<provider class-name="org.apache.commons.vfs.provider.ftp.FtpFileProvider">
<scheme name="ftp"/>
<if-available class-name="org.apache.commons.net.ftp.FTPFile"/>
</provider>
That means org.apache.commons.net.ftp.FTPFile should be in your classpath.
After I added the corresponding library it works.
Could you please check that org.apache.commons.net.ftp.FTPFile is in your
classpath?
Best regards,
Juri.

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,
Mario
