Very good, thanks for the info! Agree that only a few classes of json.org are needed (the core ones I make use of/reference in the article). I will take a look at the above URL.

In my experience the org.json.me library is overengineered and a burden on many memory constrained J2ME devices. Instead I went with Stringtree JSON, modifying it to use J2ME collections instead of Java 1.2+ ones:

http://www.stringtree.org/stringtree-json.html

The reader is just 300 LOCs and fits in a single class. Most importantly it maps all the JSON data types into existing core J2ME classes, leaving no need for boxing everything like o.j.me does. They also offer a single class writer, but StringBuffer and the built-in Java string conversions were more than enough.
