I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Such an open ended question.
Also its JSON, not Jason.

It fou want to develop spring restful services, I would find a tutorial online. So much information out there. I beleive spring already uses Jackson as the default HTTPMessageConvertor.

Do the study and come back with questions.
