FTP private directory problems with org.apache.commons.net.ftp.FTP

[magaupe]

I'm trying to access a directory that is only visible when connected with determined user. How can I do this?
This is what's going on:
Code:

connect("ftp.e***a.intranet"); 
login("f***1","****");

These to methods return me true but when I try to change directory using changeWorkingDirectory(), passing the private directory it, returns me false as if it could not find it. I verify the current directory using printWorkingDirectory() and this is the one that is coming: "/VM/maqvm/fcpc". It seems it's just not recognizing private directories cause when I change to a public one it works fine. Why is this happening?

Any help would be appreciated.
Thanks.
