copied!<p>First of all, for the client, bootstrap option should not start with 'child':</p> <pre><code>bootstrap.setOption("tcpNoDelay", true); bootstrap.setOption("keepAlive", true); </code></pre> <p>Also you don't use the same port on the client and the server!!</p> <p>Second, you have no "close" strategy: when is your client suppose to know its job is done? How do you prevent the Thread from ending prematuraly? You should do this</p> <p>SERVER HANDLER</p> <pre><code>public class ServerHandler extends SimpleChannelHandler{ public void channelConnected(ChannelHandlerContext ctx, ChannelStateEvent e){ byte[] resp=data.getBytes();//data is a String greater than 1024bytes; ChannelBuffer buffer=ChannelBuffers.buffer(resp.length); buffer.writerBytes(resp); e.getChannel().write(buffer); buffer.clear(); e.getChannel.close(); } } </code></pre> <p>CLIENT BOOTSTRAP</p> <pre><code>public class Client{ public static void main(String[] args){ ChannelFactory channelFactory=new NioClientSocketChannelFactory( Executors.newCachedThreadPool(), Executors.newCachedThreadPool()); ClientBootstrap bootstrap=new ClientBootstrap(channelFactory); bootstrap.getPipeline().addLast("handler", new PhoneClientHandler()); bootstrap.setOption("child.tcpNoDelay", true); bootstrap.setOption("child.keepAlive", true); // Start the connection attempt. ChannelFuture future = bootstrap.connect(new InetSocketAddress("127.0.0.1",8181)); // Wait until the connection is closed or the connection attempt fails. future.getChannel().getCloseFuture().awaitUninterruptibly(); // Shut down thread pools to exit. bootstrap.releaseExternalResources(); } } </code></pre> <p>Finally, you need to understand better what you are doing by reading a lot of examples. They can be found inside <strong>org.jboss.netty.example</strong> package in the main bundled download.</p>
