Need server side JSP code to extract/retrieve JSON object and send back status according to data recieved on server.

How to retrieve the JSON object that I send with HTTPClient POST method to my server. I want to retrieve this JSON object on server in my JSP page. I googled a lot but either there were no answers or they were all for PHP.
I tried many different ways to access this JSON object in my JSP page on server side, but failed in all my attempts. Also I am a bit confused with the number of JSON libraries that are available on the google.
So could you please write down the code for server side JSP page. This will be a big help for all Java developers.
