Downloading file from a database..

Question

Iam writing an application which downloads a file from the database.The file lists will be displayed for the user. When he clicks a particular file, he gets a window with open, save cancel options
(i am using response.setHeader("Content-disposition","attachment; filename="+selectedfile);
     response.setContentType("application/octet-stream");)
I am reading the file from the database and storing it in the client system and then reading it from the saved location to view the downloaded file. But when it is viewed, the file is being copied to the temporary internet files folder and from there it is shown. So the file is in the two locations at the client side...
When user downloads it i am storing it in "c:/downloade/" directory and again reading from the c:/downloaded/" to display the file. But when I see the path of the file opened through its properties its showing the temporary internet file folder location..
"C:\Documents and Settings\.....\Temporary Internet Files\Content.IE5\2RED0V4P\v[1].jpg".
Please tell me is my procedure is correct, can we view it without downloading it to the client system. I am giving the code in my program..
FileOutputStream fs=null;
               FileInputStream fis=null;
               Connection con=DBUtil.getConnection();
               Statement st=con.createStatement();
               response.setHeader("Content-disposition","attachment; filename="+selectedfile);
               response.setContentType("application/octet-stream");
               try
                    ResultSet rs=st.executeQuery("select DOCUMENT from md_documents where DOCNAME='"+selectedfile+"'");
                    fs=new FileOutputStream("C:/Documents and Settings/admin/Desktop/download/"+selectedfile);
                                        int n=0;
                    InputStream is=null;
                    while(rs.next())
                         is=rs.getBinaryStream(1);
                         int i=is.read();
                         while(i!=-1)
                              fs.write(i);
                              i=is.read();
               }catch(Exception e){System.out.println("Cause-->"+e);b=false;}
               BufferedInputStream bis = null;
               BufferedOutputStream bos = null;
               String fname="C:/Documents and Settings/admin/Desktop/download"+selectedfile;
               try{
                    fis=new FileInputStream(new File("C:/Documents and Settings/admin/Desktop/download/"+selectedfile));
               int length = fis.available();
               bis = new BufferedInputStream(fis);
               bos = new BufferedOutputStream(out);
               byte[] buff = new byte[length];
               int bytesRead;
               while(-1 != (bytesRead = bis.read(buff, 0, buff.length))) {
               bos.write(buff, 0, bytesRead);
               }catch(Exception e){System.out.println("in reading "+ e);}
               out.flush();
               out.close();
               con.close();
Please suggest me the solution..even if we have to download it to the local system..how to give the path..plz help me.

You can do this task using the packages provided to work in PSP pages. If you want I can guide step by step to this if you choose to do it with PSP pages.
