How to control the Channel out of Handler object

[Michael McGrady]

I think you want something like the following:

		DefaultHttpChunk chunk = new DefaultHttpChunk(buf);

		ChannelFuture future = e.getChannel().write(chunk);

		future.addListener(new ChannelFutureListener() {

			public void operationComplete(ChannelFuture future) {
				if (future.isSuccess()) {
				} else {
				}
			}

		});
