Write permission for user

[jonathan pietrzyk]

Hello all,
I'm using the ftp server in an embedded way. I am trying to get write 
permission for a user, unfortunately I wasn't able to make it so far.
 
1. I tried to adapt the "users.properties" file. It fails to run without that 
file, but it seems like it doesn't matter if the file is empty or not. Ideas?
 
2. I tried to set up a user manually and add write permission via the code 
(user.setAuthorities... I read this thread: 
http://www.mail-archive.com/ftpserver-users@mina.apache.org/msg01244.html ). 
Did I miss something?
 
My code (Excuse my poor programming skills, mostly c&p):
