Problem downloading file in Internet Explorer

Question

Hi, I have a problem with Internet Explorer. I want to click on a link that references a file with .dat extension, then select "Open" option and view the file in Notepad (I have the mapping with .dat files and Notepad). When I click on it, if I select "Save" option, the file is stored in disk correctly. But if I select Open opcion, Notepad opens with an error dialog:
Can't find file C:\Documents and Settings\TANDIL\Configuraci�n local\Archivos temporales de Internet\Content.IE5\LZR539BK\Mensuales.dat
Do you want to create a new file?
I think that IE doesn't copy the file correctly in temp directory ...
In my java class I set the response like this:
     resp.setContentType("binary/octet-stream");
     resp.addHeader("Content-Disposition", "attachment; filename=\"" + lote.getNombreArchivo()+ "\""); //el nombre de estos archivos son del tipo XXXXXXX.dat
     OutputStream out = null;
     try {
          out = resp.getOutputStream();
     } catch (IOException e) {
          e.printStackTrace();
out = new java.io.BufferedOutputStream(out);
     copy(lote.getArchivo().getBinaryStream(), out); // lote.getArchivo().getBinaryStream() : es un array de bytes que se copian en la salida
     out.close();
I set the response in differente ways, but I can't solve the problem ...
resp.setContentType("application/octet-stream");
resp.setContentType("text/plain");
resp.setContentType("aplication/force-download");
Thanks in advance
Regards

Hi,
I think you will get better answers if you post this question in a web related forum. The problem is not related to java but rather to http/html.
