Question

I want it got time out if the connection if lose while i read a stream from URL
try {
     int timeout = 700;
     HttpURLConnection connection = (HttpURLConnection) downloadURl.openConnection();
     connection.setConnectTimeout(timeout);
     connection.setRequestProperty("Range","bytes=" + downloaded + "-");
     connection.connect();
     if (connection.getResponseCode() / 100 != 2) {
          error();
     int contentLength = connection.getContentLength();
     if (contentLength < 1) {
          error();
     if (status == DOWNLOADING){
          if (size == -1) {
               size = contentLength;
          file = new RandomAccessFile(saveTmpName+".tmp", "rw");
          file.seek(downloaded);
     byte buffer[];
     stream = connection.getInputStream();
connection.setReadTimeout(timeout);
     while (status == DOWNLOADING) { 
          if (size - downloaded > MAX_BUFFER_SIZE) {
               buffer = new byte[MAX_BUFFER_SIZE];
          } else {
               buffer = new byte[(int)(size - downloaded)];
          int read = stream.read(buffer); // how to set timeout while it is reading stream
          if (read <= 0)
               break;
          file.write(buffer, 0, read);
          downloaded += read;
     if (status == DOWNLOADING) {
          status = COMPLETE;
} catch (SocketTimeoutException  e) {
     error();
} catch (IllegalArgumentException e) {
     error();
} catch (Exception e) {
     error();
} finally {
     if (file != null) {
          try {
               file.close();
          } catch (Exception e) {}
     if (stream != null) {

Because, there's no FTP client command that allows to do such thing.Socket.setSoTimeout().I agree with you on this one but the OP is talking about the FTPClient API from Apache.
To the OP,
BTW, I have reread the Javadoc about the [*API*|http://commons.apache.org/net/api/org/apache/commons/net/ftp/FTPClient.html] : indeed, there's no setTimeout method, but there is a setDataTimeout method : +Sets the timeout in milliseconds to use when reading from the data connection+ .
