Re: [VFS][SFTP] Unable to navigate to directory

I connect to a remote SFTP server by first creating a FileObject linked to its root folder, then I try to open a subdirectory by calling resolveFile, but it seems to fail in the middle. Here is the code : FileObject root = fsManager.resolveFile(sftp:username:passw...@server/); FileObject target = root.resolveFile(appli/myappli/data/files/ged_bur%250)); return target.getChildren().length0; I initially used target.exists(), but as it did not seems to work, I tried to check for directory content, but it also fails. Notice that when I ssh by hand to this server (with same username and password), I can without any trouble navigate to this directory. I done further exploration and notice that writing, in my debug console the following succeeded root.getChild(appli).getChild(myappli).getChild(data) while the following failed root.getChild(appli).getChild(myappli).getChild(data).getChild(files) with this exception org.apache.commons.vfs.FileSystemException: Could not list the contents of sftp://root:peri...@quasar/appli/perigee_63D/data; because it is not a folder.

No sign of 'data' yes, as I expected, files is a directory. Notice that I can also do all those SSH operations using, as an example, WinSCP. Which leads me to think that this may not be a server-side issue, but rather a problem with my use of commons VFS. So, have you got any suggestions regarding this particular issue ? Make sure the operations really are identical. They don't appear to be from your description.

Re: [VFS][SFTP] Unable to navigate to directory
So the data directory is a link to another mount. I'm not familiar with the SFTP code but my guess is there is something preventing it from following links.

Re: [VFS][SFTP] Unable to navigate to directory
I committed a patch a while ago in the FTP provider to have it support symbolic links better: https://issues.apache.org/jira/browse/VFS-196 Perhaps we need to do that with SFTP too?
