downloading a file

[james evangelisti]

my question is this:
is it possible to download a file from the application server to the client THROUGH JAVA CODE and then cancel the copy of the downloaded file on the server?
My application calls a PL/SQL stored procedure which create a file on the server and I need to have it on my client.
Thanks

Hi,
you could to try with this code:

  
       File fl = new File(fileName);
       if(fl.exists())
       {
          RandomAccessFile fo= null;
          try
          {
             fo = new java.io.RandomAccessFile(fl,"r");
             byte[] bufferIO = new byte[256];
             res.setContentType("application/binary");
             res.setHeader("Content-Disposition","attachment;filename=\"filename\";");
                            javax.servlet.ServletOutputStream out = res.getOutputStream();
                            int lun = -1 ;
                            while((lun=fo.read(bufferIO))!=-1)
                                    out.write(bufferIO,0,lun);
 
                            out.flush();
 
                            fo.close();
                            fl.delete()
                                   
                    }
                    catch(FileNotFoundException fnfe)
                    {
                    }
                    catch(IOException ioe)
                    {                            
                            if (fo!=null)
                                    fo.close();
                    }
         }
