Apex JSON App/Content Challenge


Apex JSON App/Content Challenge

Starting with the Winter '12 release, Apex includes native support for JavaScript Object Notation (JSON). Using Apex JSON classes, your Apex code can now parse JSON content and serialize Apex objects into the JSON format. The addition of native JSON support provides many benefits for Apex development, including efficient processing of JSON for HTML5 apps.

In this challenge, we want you to write a detailed "Getting Started" article on the use of Apex JSON.

  • Start the reader with some basics and context for JSON and why it's important these days.
  • Build your article around a demo app that uses the native Apex classes for exposing methods for JSON serialization and deserialization (e.g., System.JSON, System.JSONGenerator, System.JSONParser).
  • Make sure that your demo app calls a web service to send/receive JSON. We want to demonstrate real-life scenarios here.
  • Thoroughly explain your code, what you are doing, and why you are doing it. Don't assume that the reader can read your mind ;-)
