JSON implementation
Plan
Phase 1: JSON Marshalling
- Find an open source JSON library for JAVA
- Develop marshaller to transform NexJ Server Objects into JSON representation
- Develop a J2EE servlet
- Server will implement GET and DELETE methods
Phase 2: JSON UnMarshalling
- Develop an marshaller to tranaform JSON representation into NexJ Server Objects
- Extend servlet to implement POST and PUT methods
