Summary
In this chapter we covered JSON-P, which is a new addition to the Java EE
specification. We covered how to generate and parse data using the simple JSON-P
object model API, and then we switched our attention to the more performant and
memory-efficient JSON-P streaming API, covering JSON data manipulation with
this JSON-P API as well.
