I've had that issue before and fixed it. So, I know it's in the classpath. I added a Class.forName() to my code to verify and it didn't get a ClassNotFoundException. Of course, the fact that this code works sometimes and doesn't other times would lead me to believe that it's not a classpath issue. > > Best regards, > Juri. > > -----Original Message----- > From: Mario Ivankovits [mailto:[EMAIL PROTECTED] > Sent: Tuesday, January 29, 2008 4:45 PM > To: Jakarta Commons Users List > Subject: Re: [vfs] Inconsistent Behavior... > > 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 > > > 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.
