Help setting up file permissions
Hi,
I'm in the process of writing a system (in Java) where a user can register to become a member of a website.
When they register, a collection of directories and files get created by the application.
For example if a user with the name 'fred' registered they would get the following
drwxr-xr-x /usr/local/application/users/fred
-rw-r--r-- /usr/local/application/users/fred/example.css (file)
drwxr-xr-x /usr/local/application/users/fred/anotherDirectory (directory)
-rw-r--r-- /usr/local/application/users/fred/anotherDirectory/test.txt (file)

The java application server runs as root from the init.d startup process.

I've set up a pureftpd server that automatically registers people, so then they can ftp onto the box. The intention is for the user to be able to update/add/delete files for their user.

So when fred logs in his home dir to the ftp server is:
/usr/local/application/users/fred

My problem is that the directories and the files created by the application server do not have permissions for adding/updating and deleting files.

As a newbie I'm not up to the job of knowing what I should be doing.

Is there any way to enable access to do this.
Everything works fine if I chmod the files/directories before ftp'ing to the box, but as it's all supposed to be automatic from the and generated by the java web server I'm not sure what to do.

Hope the explanation makes a little sense!
Thanks
Andrew

check-permissions

check-permissions(1M)					  System Administration Commands				     check-permissions(1M)

NAME

       check-permissions - check permissions on mail rerouting files

SYNOPSIS

       /usr/sbin/check-permissions [login]

DESCRIPTION

       The   check-permissions script is intended as a migration aid for sendmail(1M). It checks the /etc/mail/sendmail.cf file for all configured
       alias files, and checks the alias files for :include: files. It also checks for certain .forward files. For each file  that   check-permis-
       sions checks, it verifies that none of the parent directories are group- or world-writable. If any directories are overly permissive, it is
       reported. Otherwise it reports that no unsafe directories were found.

       As to which .forward files are checked, it depends on the arguments included on the command line. If no	argument  is  given,  the  current
       user's home directory is checked for the presence of a  .forward file. If any arguments are given, they are assumed to be valid logins, and
       the home directory of each one is checked.

       If the special argument ALL is given,  the passwd entry in the  /etc/nsswitch.conf file is checked, and all password entries  that  can	be
       obtained through the switch file are checked. In large domains, this can be time-consuming.

OPERANDS

       The following operands are supported:

       login	Where login is a valid user name, checks the home directory for  login.

       ALL	Checks the home directory of  all users.

FILES

       /etc/mail/sendmail.cf	Defines environment for  sendmail

       /etc/mail/aliases	Ascii mail aliases file
