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

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.

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
