Json-lib

 

Welcome to Json-lib

JSON-lib is a java library for transforming beans, maps, collections, java arrays and XML to JSON and back again to beans and DynaBeans.
It is based on the work by Douglas Crockford in http://www.json.org/java.

The following tables sumarizes the types conversion between java and javascript:

JSON		Java
string	<=>	java.lang.String, java.lang.Character, char
number	<=>	java.lang.Number, byte, short, int, long, float, double
true|false	<=>	java.lang.Boolean, boolean
null	<=>	null
function	<=>	net.sf.json.JSONFunction
array	<=>	net.sf.json.JSONArray (object, string, number, boolean, function)
object	<=>	net.sf.json.JSONObject

The function type from javascript is not part of the JSON format "officially" (please refer to http://www.json.org) but it is supported as well.

Json-lib comes in two flavors, depending on the jdk compatibility. json-lib-x.x-jdk13 is compatible with JDK 1.3.1 and upwards. json-lib-x.x-jdk15 is compatible with JDK 1.5, includes support for Enums in JSONArray and JSONObject. Please reffer to the appropriate javadoc links available in the project menu.

Json-lib requires (at least) the following dependencies in your classpath:

• jakarta commons-lang 2.4
• jakarta commons-beanutils 1.7.0
• jakarta commons-collections 3.2
• jakarta commons-logging 1.1.1
• ezmorph 1.0.6

Other dependencies are needed if working with XML, Groovy and JRuby. Please review the Dependencies report to know more about those extra dependencies.
