Parsing JSON on google app engine (java)

Question

i use org.json library to work with JSON-data in my apps. But it seems that google app engine doesn\'t allow to use it, what\'s the best way to work with JSON o

Answer 1

I had the similar question a week ago and after comparing a number of Java JSON libraries (including JSonLIB and GSON) I have chosen Jackson. Check other comparisons on StackOverflow, most of them would recommend Jackson out of the rest.

After two weeks using it on Google Appengine, I just love it. Not only it has more features than the other mentioned libraries, it is also much faster (see benchmarks here). It is a Json engine in Jersey which I would recommend as well if you want to do anything Restful on Appengine.

It is stable and still actively developed, with version 2 has just been released couple of weeks ago.

UPDATE: here is a sample demo for using Jackson with GAE.
