Json-lib is a java library for transforming beans, maps, collections, java arrays and xml to json and back again to beans and dynabeans.

json (javascript object notation) is a lightweight data-interchange format. it is easy for humans to read and write. it is easy for machines to parse and generate. it is based on a subset of the javascript programming language, standard ecma-262 3rd edition - december 1999. json is a text format that is completely language independent but uses conventions that are familiar to programmers of the c-family of languages, including c, c++, c#, java, javascript, perl, python, and many others. these properties make json an ideal data-interchange language.
