Use TEXT_IO

PROCEDURE echo_file_contents IS
in_file Text_IO.File_Type;
linebuf VARCHAR2(80);
BEGIN
in_file := Text_IO.Fopen('echo.txt', 'r');
LOOP
Text_IO.Get_Line(in_file, linebuf);
Text_IO.Put(linebuf);
Text_IO.New_Line;
END LOOP;
EXCEPTION
WHEN no_data_found THEN
Text_IO.Put_Line('Closing the file...');
Text_IO.Fclose(in_file);
END;

do the client access the server via internet?
if so, then you've to code a javaservlet,
which does this for you,
otherwise you can use the text_io as above,
even if i don't know where the sample above does writes the data to

meikl ;-)

In a client\server configuration, you can use text_io in Oracle Forms to write a file to any network device or drive that the client has access to.  (That's one of the reasons our application is still client\server only.)

In a web-based Oracle Forms implementation via Oracle's 9ias Application Server you will have to use another approach, like Java.

It's exactly as markgeer says. Have a look at
http://otn.oracle.com/sample_code/products/forms/content.html

There you will  find a File Upload Utility:
"The FileUpload utility uses a combination of a JavaBean deployed as a PJC in the Forms Client and some java code called on the Application server tier via the Java Importer functionality in Forms. FileUpload will display a file selection dialog on the Browser machine and transfer the selected file up to the middle tier."

A little bit down that page you will find the source code,
viewlets and a readme.

Hope this helps.
