You need a JSON library in Java. With that library, you will be able to serialize Java Objects into JSON objects, and send them through HttpServletResponse instance in your Servlet.

"How do you use it"?
JSON is simply one way of representing hierarchical data (such an an object model) in a flat text format (such as an HTTP body, or filesystem file). So you'd use it to represent hierarchical data in these situations.
If you mean how do you parse/create it, there are many mature libraries for JSON handling.
Perhaps a specific situation or use case would assist in pinning down your question, if the above is not the answer you were looking for.
