Need help with java.nio.socket program.

Question

Can someone please help me here? I am trying to create a class that listens on a socket for an incoming connection, but I am getting the following error on compile:
SocketIn.java:48: incompatible types
found : java.nio.channels.SocketChannel
required: java.net.Socket
Socket requestSocket = requestChannel.accept();
Here is my code:
package NETC;
import java.net.*;
import java.util.*;
import java.io.*;
import java.nio.*;
import java.nio.charset.*;
import java.nio.channels.*;
import java.nio.channels.spi.*;
public class SocketIn{
     // Buffer for any incoming data.
     private static ByteBuffer inBuffer = ByteBuffer.allocateDirect(1024);
     CharBuffer charBuffer = null;
     public SocketIn(int intPort)throws Exception{
          // Create a non-blocking server socket.
          ServerSocketChannel serverChannel = ServerSocketChannel.open();
          serverChannel.configureBlocking(false);
          // Use the host and port to bind the server socket.
          InetAddress inetAddress = InetAddress.getLocalHost();
          InetSocketAddress socketAddress = new InetSocketAddress(inetAddress, intPort);
          serverChannel.socket().bind(socketAddress);
          // The selector for incoming requests.
          Selector requestSelector = SelectorProvider.provider().openSelector();
          // Put the server socket on the selectors 'ready list'.
          serverChannel.register(requestSelector, SelectionKey.OP_ACCEPT);
          while(requestSelector.select() > 0){
               System.out.println("Connection Accepted...");
               // A request has been made and is ready for IO.
               Set requestKeys = requestSelector.selectedKeys();
               Iterator iterator = requestKeys.iterator();
               while(iterator.hasNext()){
                    SelectionKey requestKey = (SelectionKey)iterator.next();
                    // Get the socket that's ready for IO.
                    ServerSocketChannel requestChannel = (ServerSocketChannel)requestKey.channel();
                    // This shouldn't block.
                    Socket requestSocket = requestChannel.accept();
                    inBuffer.clear();
                    requestSocket.read(inBuffer);                    
                    inBuffer.flip();
                    Charset charset = Charset.forName("ISO-8859-1");
                    CharsetDecoder decoder = charset.newDecoder();
                    charBuffer = decoder.decode(inBuffer);
                    iterator.remove();                    
}

Well its been about a month and a half so I guess you have your answer. In case you don't...
// This shouldn't block.
Socket requestSocket = requestChannel.accept();
The problem is quite simple. The ServerSocketChannel.accept() returns a SocketChannel. (Channel -> Channel).
You can get access to the socket using the SocketChannel.
SocketChannel requestSocketChannel = requestChannel.accept();
Socket requestSocket = requestSocketChannel.socket();
But you don't need the socket to read and write.
