To display the list of File Name in a report region from a Directory

Question

Hello All,
Can any one guide me in displaying the list of file name from a file system directory in a report region with link?
On click of the link it should display the open/save dialog box.
I will appreciate the early solution. (It is bit urgent)
Thanks,
Shyam

A quick, "dirty solution would be to have a cron job (I am assuming you are on a UNIX-based system) that populates a file periodically with the names of files in a directory/directories. Then have an external table that points to that file. You can then create an Apex report that lists the contents of the external table.
1) crontab job:
ls -1 /source_dir/* > /destination_dir/file.list
2) create external table:
CREATE DIRECTORY filedir AS ' destination_dir ';
GRANT READ ON DIRECTORY xfer_files TO public;
CREATE TABLE file_list_ext (file_names VARHCAR2(100))
ORGANIZATION EXTERNAL
TYPE oracle_loader
DEFAULT DIRECTORY files_dir
ACCESS PARAMETERS
records delimited by newline
fields terminated by ','
missing field values are null
(file_name)
LOCATION ('file.list')
REJECT LIMIT UNLIMITED;
3) create APEX report on table: file_list_ext
Hope this helps.
