TCP Read Locks up System

Question

Hi,
I'm attempting to read a line from a TCP Socket using the following code, but for some reason, it locks up my system. Can anyone explain why?
          try
               Socket sock;
               BufferedReader istream;
               BufferedWriter ostream;
               //PrintStream ostream;
               String readstring;
               sock = new Socket("my-server-tis-of-thee",5100);
               istream = new BufferedReader(new InputStreamReader(new DataInputStream(sock.getInputStream())));
               ostream = new BufferedWriter(new OutputStreamWriter(new DataOutputStream(sock.getOutputStream())));
               ostream.write("Shoo fly last\n");
               while((readstring = istream.readLine()) != null)
                    System.out.println(readstring);
                    if(readstring.contains("rawr"))
                         break;
               System.out.println("closing sockets");
               ostream.close();
               istream.close();
               sock.close();
          catch(Exception ex)
               ex.printStackTrace();
          }I'm able to open up the socket correctly, but for some reason, and the code executes fine as long as I comment out the "while" loop, but when I throw it in, everything freezes up. Any suggestions?
Thanks,
hhung

Answer 1

... presumably by putting the blocking I/O in a different thread from the AWT event thread ...
