Give this a try:
File strFile = new File(strFileName);
long length = strFile.length();
response.setContentType("application/octet-stream");
response.setContentLength((int)length);
response.setHeader("Content-Disposition", ("attachment; filename=" + strFileName));
OutputStream out = response.getOutputStream();
BufferedInputStream in = new BufferedInputStream(new FileInputStream(strFile));
int i = -1;
while((i = in.read()) != -1) out.write(i);
in.close();
