FileSystems explained

Hi,

I am just playing around with Apache FtpServer. My plan is to integrate 
it into a spring-based webapplication as a means to exchange files like 
firmware-updates for client-software with embedded clients that are 
distributed in the field.

I like the idea of having that server running in the same application 
context and not alongside it for things like common logins, common 
logging, tracking of transaction etc. I think FtpServer would be 
perfectly suited to my needs.

So far I got the basic integration going, including a context listener 
to start() and stop() the server and a custom UserManager to link to the 
security infrastructure already in place.

Very nice. I can now log in using a ftp client!

But I can't figure out what my server is actually serving and how to 
control that. I have not explicitly set up any filesystem-related 
options, my context-file for setup is attached. I suspect that is 
actually the problem. So here is the question:

How do I setup the filesystem?

I am running FtpServer 1.0.0 on Windows. Developing my application in 
and around Spring 2.5. The IDE is Eclipse 3.3 but I doubt that that 
matters. Any other relevant information I would be happy to provide.

When I connect to the server using Filezilla as a client the client 
complains that it cannot list the directory while the server logs this:

 >WARN [org.apache.ftpserver.listener.nio.FtpLoggingFilter] - SENT: 331

I also tried to create a directory, hoping it would show me where it was 
trying to do so:

The file system defaults to a native file system. The home directory
is to be provided per user, so that should come from your custom
UserManager. Now, where are you planning to serve the files from (a
normal file system, database, something else)?
