Server;

import java.io.IOException;
import java.io.ObjectInputStream;
import java.net.InetSocketAddress;
import java.nio.channels.ServerSocketChannel;
import java.nio.channels.SocketChannel;

/**

public class Server {

/**
 * @param args
 * @throws IOException 
 * @throws ClassNotFoundException 
 */
public static void main(String[] args) throws IOException, ClassNotFoundException {
    Server server = new Server();
    server.ReceiveObject();
}

private SocketChannel socketChannel = null;

void ReceiveObject() throws IOException, ClassNotFoundException{
    System.out.println("Server Started");
    socketChannel = CreateSocketChannel();
    ObjectInputStream ois = new ObjectInputStream(socketChannel.socket().getInputStream());
    Person person = (Person) ois.readObject();
    System.out.println("Object : "+ person.toString());
    socketChannel.close();

}
private SocketChannel CreateSocketChannel() throws IOException{

    ServerSocketChannel serverSocketChannel = ServerSocketChannel.open();
    serverSocketChannel.socket().bind(new InetSocketAddress(9100));
    socketChannel = serverSocketChannel.accept();

    System.out.println("Connection Etablished : " + socketChannel.getRemoteAddress());
    return socketChannel;
}

}

Client

import java.io.IOException;

public class Client {
boolean isConnected = false;
private SocketChannel socketchannel;
private ObjectOutputStream outputStream;
public static void main(String[] args) throws IOException {
    Client client = new Client();
    client.sendOject();
}
/**
 * @param args
 */
    SocketChannel createChannel() throws IOException {      
        SocketChannel socketChannel = SocketChannel.open();
        socketChannel.configureBlocking(true);
        SocketAddress sAddr = new InetSocketAddress("127.0.0.1", 9100);
        socketChannel.connect(sAddr);
        return socketChannel;
    }
        void sendOject() throws IOException {
            while (!isConnected) {
                socketchannel = createChannel();
                isConnected = true;
                outputStream = new 
ObjectOutputStream(socketchannel.socket().getOutputStream());
                Person person = new Person(15, "Hello");
                outputStream.writeObject(person);

    }
}
