RE: Using Apache VFS to FTP to the AS/400 IFS -- JAVA400-L

Sarah:

Got it! This modification of your program works correctly on my system!

The part that got me was that file name on the i5 is very case
sensitive.

Work link shows the folder name as "/Blalock".

"/blalock/clean_debug.log" works if file is present in IFS but fails if
"clean_debug.log" is not there. It tries to create a folder "/blalock"
and fails (thankfully!!!!)

"/Blalock/clean_debug.log" works either way.

Note that I added a check for the parent of the remote file. The remote
file may or maynot be present, usually not I would guess. The parent of
the remote file needs to be present. My check assumes only one level
but you get the idea.

Your program tinkered with ....

Thanks for pointing this tool out!

Bill- Were you able to use my simple Java class to try out an FTP
upload with Apache VFS?

Good morning Sarah

Apache VFS uses Jakarta Commons Net for the FTP part.

With luck the Net part will take initialization parameters, and may

even

have a console which could show the dialog between the client and
server.

I've downloaded the source for these projects because I am curious

and I

will learn things applicable to my projects.

Could you send me a stand alone sample program which transfers using
FTP?
