Hi Mario:
I am sometimes dumber than the average bear. I made sure to add the
appropriate libs
and ran it from the command line. I killed the program when it hung.
Here is the code, log and
stack trace. Thanks.

Hi Mark!
If I run the program from eclipse it hangs, argggg.
When I run it from the command line it runs but says
the dir is imaginary and doesn't exist.
Do you have commons-net in your classpath, else it will use java's URL
and this is somewhat limited.
Well, if you say ftp-check works you should have ...
No additional idea. We need a stacktrace - or even better - try to debug
into VFS :-)
