Download ascii file procedure -problem as its getting binary after download

Question

Hi ,
I have create a application that will download a file from a customised blob table by calling the procedure below which is as per oracle documentation:
CREATE OR REPLACE PROCEDURE download_my_file(p_file IN NUMBER) AS
v_mime VARCHAR2(48);
v_length NUMBER;
v_file_name VARCHAR2(400);
Lob_loc BLOB;
BEGIN
SELECT b.MIME_TYPE, a.file_content, a.file_name,A.file_size
INTO v_mime,lob_loc,v_file_name,v_length
FROM PCD_PROCESS_TBL a,PCD_CNTL_TBL b
WHERE a.seq_no =p_file AND ROWNUM<2;
-- set up HTTP header
-- use an NVL around the mime type and
-- if it is a null set it to application/octect
-- application/octect may launch a download window from windows
owa_util.mime_header( NVL(v_mime,'text/plain'), FALSE,'ISO-8859-4' );
-- set the size so the browser knows how much to download
htp.p('Content-length: ' || v_length);
-- the filename will be used by the browser if the users does a save as
htp.p('Content-Disposition: attachment; filename="'||SUBSTR(v_file_name,INSTR(v_file_name,'/')+1)|| '"');
-- close the headers
owa_util.http_header_close;
-- download the BLOB
wpg_docload.download_file( Lob_loc );
END download_my_file;
The problem is that when our process updating the blob table with .dat file from Unix the data getting inserted fine.The file is basically a ascii file. But after downloading this by mime 'text/plain' or 'application/octet' i can see its getting as a binary file and it is not carriage return by a new line.A space like character getting inserted inside each line .
can anybody please help out of that how can we get rid of this.
I even change the blob to clob but still the problem persists even for clob the procedure not getting called.
Thanks in advance,
Deba

Sounds like the problem you're having is the mismatch between the Unix text file format and the Windows text file format.
Specifically, Unix uses LF (line feed) to denote the end of a line, while Windows uses CRLF (two characters, carriage return and line feed).
If you open the file in Wordpad, you should see it ok.
