Below a demo of what it's possible now (notice that I didn't perform any =
installation or configuration before executing the following =
statements). On my opinion non difficult at all...

- connect via SQL*Plus and create a view MYFTP

linux:oracle:A1010 /u00/app/oracle> sqlplus system/manager

[snip version information, in my case]

SQL> create or replace view myftp as
  2  select * from resource_view where under_path(res,'/public')>0;

View created.

SQL> select * from myftp;

no rows selected

SQL> exit

- connect via FTP to the database (authentication performed with DB =
account), change directory and upload a file

linux:oracle:A1010 /u00/app/oracle> ftp linux 2100 Connected to =
220 linux FTP Server (Oracle XML DB/Oracle Database 10g Enterprise =
Edition Release - Production) ready.

- connect via SQL*Plus and show the file uploaded in the database

linux:oracle:A1010 /u00/app/oracle> sqlplus system/manager

[snip version information, in my case]

SQL> select any_path from myftp;


SQL> set long 100000
