java - Apache FTPClient hangs during the retrieveFileStream -


dear have problem code. ftp client hanging when retrieving file "ftpclient.retrievefilestream()". idea can do? using apache commons ftp client v3.4.

  • i tried "ftpclient.retrievefile()" did not make difference.
  • setting connection , scoket timeout did not help
  • setting passive mode did not help

  • increasing buffer did not help

            ftpclient = new ftpclient();         ftpclient.setbuffersize(1024 * 1024);         ftpclient.setconnecttimeout(10000);                       ftpclient.connect(serveraddress);         ftpclient.login(username,password);         ftpclient.setfiletype(ftp.binary_file_type);         ftpclient.enterlocalpassivemode();         ftpclient.setsotimeout(10000);          log("retriving file " + remotefilepath + "...");         outputstream output = new fileoutputstream(localfilepath);         inputstream inputstream = ftpclient.retrievefilestream(remotefilepath); // here hanging.         try {             ioutils.copy(inputstream, output);             output.flush();         }          {             ioutils.closequietly(output);             ioutils.closequietly(inputstream);             ftpclient.completependingcommand();         }

the last message retrieve looking this:

19:58:21.145 [main] info  ftpdao: retrieving file /modell/5250/artikel/25777/lg_keh68bgh_1.jpg... 19:58:21.145 [main] info  log4jftpcommandlistener - >> pasv 19:58:21.462 [main] info  log4jftpcommandlistener - << 227 entering passive mode (195,216,65,165,168,240) 19:58:21.476 [main] info  log4jftpcommandlistener - >> retr /modell/5250/artikel /25777/lg_keh68bgh_1.jpg 19:58:21.490 [main] info  log4jftpcommandlistener - << 150 connection accepted

when suspend programm debugger, looks hanging @ 

 java.net.socketinputstream.socketread0(filedescriptor, byte[], int, int, int)   java.net.socketinputstream.socketread(filedescriptor, byte[], int, int, int) line: 116   java.net.socketinputstream.read(byte[], int, int, int) line: 170     java.net.socketinputstream.read(byte[], int, int) line: 141

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
