Greetings,
I have a question on how to buffer a HttpResponse and perform some
operations in each iteration. In short, I would like to buffer a
FileEntity response and update a JProgressBar with the transfer
progress of the FileEntity. Below is my code snippet:
response.setStatusCode(HttpStatus.SC_OK);
File fSharedFile = new File(getSharedFiles().get(path));
String sFileName = fSharedFile.getName();
if (fSharedFile.exists()) {
//display progress bar and set the size
showUlProgressBar(fSharedFile.getName());
setUlProgressBarSize(sFileName,
Integer.parseInt(String.valueOf(fSharedFile.length())));
FileEntity body = new FileEntity(fSharedFile,
"application/octet-stream");
body.setChunked(true);
BufferedHttpEntity bufBody = new
BufferedHttpEntity(body);
response.setEntity(bufBody);
InputStream in = bufBody.getContent();
OutputStream out = new
HttpDataOutputStream(new
SocketHttpDataTransmitter(htRequests.get(this.thisConn.toString()), 8
* 1024));
System.out.println("Serving file " +
fSharedFile.getPath());
// Transfer bytes from in to out
byte[] buf = new byte[8 * 1024];
int len;
int iTransferredSize = 0;
while ((len = in.read(buf)) > 0) {
out.write(buf, 0, len);
iTransferredSize += len;
//update file transfer progress
updateUlProgressBar(sFileName, iTransferredSize);
}
System.out.println("Done serving file " +
fSharedFile.getPath());
//Close streams
in.close();
out.close();
//hide progress bar
hideUlProgressBar(fSharedFile.getName());
}
The response will be sent to the client but it will be malformed. For
some reason the client receives the HTTP stream but is unable to act
on it.
I would be really glad if someone could point me in the right direction.
Thanks in advance.
