• Answer:

  Try this first just to make sure you're seeing any data from your stream. This reads in characters without worrying about the newline. Note that if you have binary (non-text) data coming from your stream, you console is going to make weird beeps. char[] data=new char[1024]; int cnt=-1; while((cnt=br.read(data)!=-1) { System.out.write(data,0,cnt); } BTW, the best idiom for reading from a BufferedReader is this: String line=null; while((line=br.readLine())!=null) { ... }
