ok, trying again, it looks formatted in hotmail editor:
I have a file download servlet running on Tomcat, the code is
public void service(HttpServletRequest request, HttpServletResponse
response) throws IOException { byte buf[] = new byte[1024 * 4];
try { File file = new File(realFilename); int size =
(int) file.length(); BufferedInputStream realFile = new
BufferedInputStream(new FileInputStream(file)); OutputStream out =
response.getOutputStream(); response.setContentLength(size);
while (true) { int count = realFile.read(buf);
if (count == -1) { break; }
out.write(buf, 0, count); } out.flush(); } catch
(FileNotFoundException e) { logger.error("Stream download failed,
file not found: " + realFilename, e); response.sendError(404);
} catch (Exception e) { logger.error("DownloadException:", e);
} }
However once in a while I get an error that prevents files from being
downloaded:
