Client stuck in loop

Question

the following method sends a file to the server...
/* Sends the file to the server.
     private void sendFile() {
          try {
               BufferedOutputStream bos = new BufferedOutputStream(clientSock.getOutputStream());
               FileInputStream fis = new FileInputStream(f);
               byte[] buffer = new byte[1024];
               int i = 0;
               int p = 0;
               while ((i = fis.read(buffer)) != -1) {
                    bos.write(buffer, 0, i); //*
                    p += i;
                    updateProgress(p);
               if (p == FileSize) //file is fully sent
                    isComplete = true;
               fis.close();
               bos.close();
          catch (IOException e) { new HermesDialog(frame).showMessageDialog("Unknown Error 8159", "If you see this again, please contact the author."); }
     }when i terminate the connection on the server side, the client stops at the line marked with the commented * and stays there. is there some way to know that the connection has been terminated and break out of the loop? i have already tried...
Socket.isConnected()
Socket.isClosed()
Socket.isInputShutdown()
Socket.isOutputShutdown()

Answer 1

That's odd, you should get an exception for attempting to write to a closed socket. Are you sure the server didn't just stop reading? If that happens your writes will eventually block.
The correct way to handle this is to read from the socket, you will get an empty read when the socket closes.
