Embeding Uploaded PDF Static Files - Problems

Question

Good morning all.
I have an application where users enter details and need to read through a selection of documents depending on what details they entered. I have uploaded 5 documents to my Apex server and used the following code to embed them inline (within the HTML itself)
<EMBED
SRC="http://server_name:7777/pls/apex/wwv_flow_file_mgr.get_file?p_security_group_id=824213546944709&p_fname=file1.PDF&p_inline=NO"
HEIGHT=500 WIDTH=800>This code was taken from the links on the Shared Components -> Static Files page in the Application builder
This all worked file on my development server, all the documents were displaying inline with the HTML document (Example - http://www.planetpdf.com/mainpage.asp?webpageid=1682 Example #1)
However, I realised one of the documents being displayed was wrong - file 1 was showing instead of file 2. I had embeded the wrong file in the page. So I just changed the &p_fname to file2.pdf. When I ran the page, all the other embeded documents were working fine, but the recently updated one was popping out of the window, and the region where I embeded the file was blank.
Now, I just exported my application to a new server for testing, and have had to change all the embeded regions to point to the newly uploaded files on the new server. None of these now show anything. They either show the little picture icon (red square, blue circle, red triangle) if I include the &p_inline=YES code, the same icon if I say &p_inline=NO instead, or if I drop this argument, the entire region is blank, and the Adobe PDF icon displays streched across the region after a new seconds.
Any hints?
Cheers,
Kate

Thanks for that Denes.
I just have one question - the source for your XML Report region shows the following code
DECLARE
   v   VARCHAR2 (200);
BEGIN
   v :=
         'SELECT '
      || '''<iframe src="#OWNER#.File_Table_Disp_Pr?p_file='
      || 2967670122524254593
      || '"'
      || ' height="880" width="600"></iframe>'''
      || ' document_display'
      || ' FROM DUAL';
   RETURN v;
END;The "2967670122524254593" refers to that file that was uploaded, yes? How do I find this number for my uploaded documents? I think it was a table somewhere, but I can't for the life of me remember which one.
Update: I found it - apex_applcation_files. I should just be able to insert the ID of the document I want in there, yes? I copied my document ID number (select id from apex_application_files) but the document is 404'ing on me.
help?
