netty处理websocket请求

哪位亲，给看下。
netty v3.9.4
做了个netty接websocket的例子，但是请求类型判断始终是HttpRequet，没有WebSocketFrame请求，结果是这样的：
message:class org.jboss.netty.handler.codec.http.DefaultHttpRequest
HttpRequest uri:/websocket
HttpRequest method:GET
message:class org.jboss.netty.handler.codec.http.DefaultHttpRequest
HttpRequest uri:/web4/http11client.jsp?q=a11
HttpRequest method:GET

import org.jboss.netty.channel.ChannelHandler;

import org.jboss.netty.channel.ChannelHandlerContext;

import org.jboss.netty.channel.MessageEvent;

import org.jboss.netty.channel.SimpleChannelHandler;

import org.jboss.netty.handler.codec.http.HttpRequest;

import org.jboss.netty.handler.codec.http.websocketx.TextWebSocketFrame;

import org.jboss.netty.handler.codec.http.websocketx.WebSocketFrame;



public class HttpServerChannelHandler extends SimpleChannelHandler {

	@Override

    public void messageReceived(ChannelHandlerContext ctx, MessageEvent e) {

        Channel ch = e.getChannel();

        Object message = e.getMessage();

        

        System.out.println("message:"+message.getClass());        

        if(message instanceof WebSocketFrame){

        	if(message instanceof TextWebSocketFrame){

				TextWebSocketFrame req = (TextWebSocketFrame) message;

				System.out.println("wsRequest text:"+req.getText());

			}

        }else if(message instanceof HttpRequest){

        	HttpRequest req = (HttpRequest) message;

			System.out.println("HttpRequest uri:"+req.getUri());

			System.out.println("HttpRequest method:"+req.getMethod());

        }

    }

}
