Custom HttpMessageConverter with @ResponseBody to do Json things

Hello there, people,

I don't like Jackson.
I want to use ajax but with Google Gson.
So I'm trying to figure out how to implement my own HttpMessageConverter to use it with @ResponseBody annotation.
Can someone take a time to show me the way I should go? What configurations should I turn on?
Also I'm wondering if I can do this and still use <mvc:annotation-driven />?

Thanks in advance.

You may see that it took me some time to find the answer. And I had to do it on my own.
Now I'm here to share it with you 'couse it was hard... realy hard!!!
