JSON Adapter

Goal

Add ability to access NexJ Server objects as JSON via a RESTful web service

Plan

Phase 1: Design Proposal

  • Get requirements from NexJ
  • Incorporate requirements from NexJ into Design of JSON Adapater
  • Proposal proposal for review, make changes as by NexJ until approved

Phase 2: Coding

  • JSONMarshaller
    • Develop marshaller to transform NexJ Server Objects into JSON representation
  • JSONUnmarshaller
    • Develop an marshaller to transform JSON representation into NexJ Server Objects
  • JSON Server
    • Develop a JSON Server to expose NexJ Server objects in JSON
  • Demo application that interacts with the Server using JSON
    • Read Server Objects
    • Update Server Objects
    • Create Server objects

Phase 3: Code Review 1

  • Send patch to NexJ for review

Phase 4: Make Changes as per Code Review 1

  • Refactor JSONSever and TextServer to inherit from GenericCharacterStreamHTTPServer
  • Optimize marshaling of nested Pair objects
  • Rename variables and methods as per NexJ Developer's Guide

Phase 5: Code Review 2

  • Send patch to NexJ for review

Status

Phase 1: done Phase 2: done Phase 3: done Phase 4: done Phase 5: On-going
