Java server side json API to marshall json to Java Objects

Hi,

I am new to Backbase. I am interested in Struts Connector right now. I understand that on the client side JSON serialize is available through engine json.js. I am trying to figure out whether any server side API is available to convert the client side json object to Server side java objects? I know I can use json.org java code, but I am just wondering whether backbase has any code to do that so that if there is any issue with json.org code we can get some support/fix from backbase.

Thanks
