Javascript to download a custom pdf

Question

Hi all, 
I am a pretty adept captivate user, but really have no javascript skill.  I have a button in my project, that when pressed I want to download a custom pdf that pulls from a jpg image and two project variables.  (Essentially I'm creating a certificate but I don't want to be limited to the certificate widget).  Does anyone have same sample script for executing this that they could share?
Thanks!

You can use a procedure like this to allow a download of your file stored as a bfile (in a directory):
   PROCEDURE download_bfile (
      file_in        IN   VARCHAR2 DEFAULT 'test.txt',
      directory_in   IN   VARCHAR2 DEFAULT 'DATA_PUMP'
   AS
      lob_loc    BFILE;
      v_mime     VARCHAR2 (48) DEFAULT 'application/txt';
      v_length   NUMBER;
   BEGIN
      lob_loc := BFILENAME (directory_in, file_in);
      v_length := DBMS_LOB.getlength (lob_loc);
      OWA_UTIL.mime_header (NVL (v_mime, 'application/octet'), FALSE);
      HTP.p ('Content-length: ' || v_length);
      HTP.p (   'Content-Disposition:  attachment; filename="'
             || SUBSTR (file_in, INSTR (file_in, '/') + 1)
             || '"'
      OWA_UTIL.http_header_close;
      WPG_DOCLOAD.download_file (lob_loc);
   END download_bfile;To make this procedure working from apex, you can use approach similar to this one:
