Java API for JSON Processing (JSR 353)
Computer programs are the most complex things that humans make.
Java API for JSON Processing (JSR 353) is one of the 4 new APIs added to Java EE 7 alongs with the Batch API (JSR 352), the WeSocket API (JSR 356) and the Concurrency Utilities for Java EE API (JSR 236). JSR 353 provides an API to parse, transform, and query JSON data using the object model or the streaming mode.
Java has a long history of various JSON APIs but the value of JSON-P (JSR 353) is the fact that it has been standardised. That means that we can expect this API to work seamlessly on any Java EE 7 implementations, i.e. GlassFish 4, JEUS 8 and WildFly 8 today. And this is juts the beginning, we can also expect the adoption of JSON-P API to rapidly grow. For example, the upcoming WebLogic 12.1.3 will add support for various Java EE 7 APIs including JSON-P, see here. It should be mentioned that binding is not yet covered by this specification but JSON-B is high on the wish-list for Java EE 8.
To know more about JSON-P, you can read the JSON-P chapter of the Java EE 7 Tutorial.
