Why am I getting java.io.IOException: Stream is closed?

Question

I try to load a zip file, but I get a Closed stream exception . When I use swing gui, it gets this erro, but if I use the console, there is no problem. Why am I getting this exception? How can i fix this?

This is my code:

URLConnection conn = url.openConnection(); InputStream in = conn.getInputStream(); FileOutputStream out = new FileOutputStream(destination.getPath()); byte[] b = new byte[1024]; int count; while ((count = in.read(b)) >= 0) { out.write(b, 0, count); } out.flush(); out.close(); in.close(); OptionPane.showMessageDialog(null, "Download is finished"); } catch (HttpUnauthorizedException e) { JOptionPane.showMessageDialog(null, "Proxy or Server Authentication Required"); } catch (IOException e) { System.out.println(e.getMessage()); } 

this is a stack trace

Answer 1

This exception usually means that the connection was closed abruptly. I would look at the logs on the server to see if there was an error.

Answer 2

this may be due to JVM delays, may be caused due to the random number generator of the unix / linux operating system. You should replace it with /dev/./urandom

Answer 3

I solved this when I removed this Primefaces tag from my xhtml.
