What is the best way to convert JSON value to java object so that it can be sent

to server? It needs to be free / open source.

Checkout Google Gson library (Apache license) that we authored:



http://code.google.com/p/google-gson/



There are other Java libraries linked at json.org as well.

Just to make sure: if you already have JSON content, why would you

need to convert it to Java object?

Couldn't you just send it as is?



But assuming this makes sense, in addition to google-gson which was

mentioned and can do this, some (not all) of libs listed at json.org

can do data binding:



* Jackson (http://wiki.fasterxml.com/JacksonInFiveMinutes)

* Json-tools (http://developer.berlios.de/projects/jsontools/)



most other alternatives only provide either tree-based access, or

mapping to 'simple' java types (List, Maps, Booleans, Numbers,

Strings). Which are of course java objects, strictly speaking, but I

assume you would want custom beans etc, sort "real" objects.

http://jabsorb.org is both a java<-->json codec and a full json-rpc

framework.  It is light, simple, mature, fast and awesome!... but of course

I'm a little biased :)

[Non-text portions of this message have been removed]

See JAJB (http://jajb.sourceforge.net/) too. Convert json to java using

annotation and/or XML and/or dynamic binding.

The Waterken Server <waterken.sf.net> includes a library for JSON <=>

Java object conversion. There's also a simple wrapper class that

facilitates using JSON configuration files, see:
