Answer 1

// I got this from an Action (I�m using Struts)
java.sql.Blob file=(java.sql.Blob)request.getAttribute("PDFfile");
String filename=(String)request.getAttribute("filename");
try{
  int iLength = (int)(file.length());
  response.setHeader("Content-type", "application/pdf");   
  response.setHeader("Content-Disposition", "inline; filename=\""+filename+"\"");
  response.setHeader("Expires","0");
  response.setHeader("Cache-Control","must-revalidate, post-check=0, pre-check=0");
  response.setHeader("Pragma","public");
  response.setContentLength(iLength);
  ServletOutputStream os = response.getOutputStream();
  InputStream in = null;
  in = file.getBinaryStream();
  byte buff[] = new byte[1024];
  while (true) {
      int i = in.read(buff);
      if (i<0) break;      
      os.write(buff,0,i); 
  os.flush();
  os.close();
} catch(Exception ex){
   out.println("Error while reading file : " + ex.getMessage());
}and now it�s running !!! I�m not using response.setContentType(...) and I do this in response.setHeader("Content-type", "application/pdf"). And I use response.setHeader("Content-Disposition", "inline; filename=\""+filename+"\"") instead of response.setHeader("Content-Disposition", "attachment; filename=\""+filename+"\"");
