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

I'm not sure too sure about FTP and don't fully get the context in which you
are using it, but..


There is an AS400FTP class in the java toolbox, could you use that instead?

com.ibm.as400.access.AS400FTP

Hi Sarah,

Since you're not using FTP directly (i.e. with VFS as an intermediate
layer) your only option may be to change the system default to *PATH
naming (NAMEFMT 1) via the CHGFTPA command. Of course this may break
other things which expect *SYS naming (NAMEFMT 0) so be sure to check
with any appropriate parties first.

If you were using a different FTP client you might be able to use an
FTP site command to issue a literal SITE NAMEFMT 1 to the FTP server
to effect this switch. This may somehow be possible with VFS but I'm
not familiar with it at all so I can't make a recommendation there.
Another trick would be to force the first command of your FTP session
to be a CD such that the directory specified starts with a slash (e.g.
"CD /home/aplsup"), in which case the leading slash would trigger an
implicit switch to *PATH naming for that session...

If you're looking for an FTP client library I can recommend jScape's
(commercial license) which I quite like. I've also used /n software's
(also commercial), which I quite dislike.

I have been using the Apache VFS API's to upload to Unix FTP servers

can upload to QGPL, but not the IFS.

Below is an excerpt from my Java code:

FileSystemManager mgr;
try {
mgr = VFS.getManager();

FileSystemOptions fileSystemOptions;
FileSystemOptions opts = new FileSystemOptions();
fileSystemOptions = opts;
FtpFileSystemConfigBuilder
.getInstance().setUserDirIsRoot(fileSystemOptions,
true);

String strLocalFile =

"C:\\sgladstone\\edfiles\\mydata.txt";

FileObject foLocalFile =

mgr.resolveFile(strLocalFile);

String rUrlStr =
"ftp://myusername:mypassword@myas400/home/aplsup/sarahtest.txt"; ;
FileObject foRemoteFile = mgr.resolveFile( rUrlStr,

opts);

FileSelector fS = Selectors.SELECT_SELF ;
foRemoteFile.copyFrom(foLocalFile, fS);


When I run this code, it throws the exception:

Caused by: org.apache.commons.vfs.FileSystemException: Could not
create FTP directory "ftp://myusername:mypassword@myas400/home";


I think this issue is caused by the AS/400 trying to use System
naming, instead of using NAMEFMT=1.

Any ideas of how to get the VFS APIs to get the AS/400 to switch to
NAMEFMT =1 ?

Thanks,
Sarah
