echo server example

[Mark Webb]

I am trying to get the Echo server example working in the 1.1 branch with a
simple telnet application.  I hope to use this echo server for more in the
near future, but I have run into a problem I can't seem to fix.  I start up
the EchoServer example and telnet to port 8080.  I type in something like
"Hello World", and never get anything back.  I am not sure if this is a
problem with the codec, the telnet program or something else.  I even wrote
a simple program that looks like the following:

for( ; ; ){

               Socket socket = new Socket( host, port );
               OutputStream out = socket.getOutputStream();
               InputStream in = socket.getInputStream();

               out.write( "Hello World\r\n".getBytes() );
               out.flush();

               int read = 0;
               byte[] buf = new byte[16];
               while( (read = in.read(buf)) != -1 ){
                   System.out.println( new String(buf,0,read) );
               }

               socket.close();
               Thread.sleep(1000);
           }

The problem is that the first call to in.read(buf) works fine.  The second
call hangs and waits for more data.  I am getting this problem without
modifying the EchoServer code, so I think I need some help.

Thank you.
