Re: non blocking echo client problem

i tried to implement a non blocking echoclient using java.nio
it connects to an echoserver and takes userinput and writes to
server .Then it reads from server and prints the server message

however ,i found that the socketchannel.isConnected() is false in the
while loop where key.readyOps is equal to OP_CONNECT

i am not sure what i am doing wrong..Am a beginner with nio and
networking..can someone help?

here is the code>>>

import java.io.*;
import java.nio.*;
import java.nio.channels.*;
import java.net.*;
import java.util.*;
public class EchoClient {
        int port;
        ByteBuffer buf=ByteBuffer.allocate(1024);
        Selector sel=null;
        SocketChannel sc=null;
        public EchoClient(int p)throws IOException{
                port=p;
                initClient();
        }
        private void initClient()throws IOException{
                sel=Selector.open();
                sc=SocketChannel.open();
                sc.configureBlocking(false);
                sc.connect(new
InetSocketAddress(InetAddress.getLocalHost(),this.port));
                sc.register(sel, SelectionKey.OP_CONNECT);
