That's a lot of code just to say hello in your browser. I found this on http://xuwei-k.github.com/gist/ ( <- very cool btw ) .

Here's the equivalent in unfiltered https://gist.github.com/1397029

Of cause I already know that if using unfiltered , code is simply.

I wrote this code with reference unfiltered jetty module :)
