I got this error
class file for java.util.Map not found
on this line of code:
JSONObject json = new JSONObject(jsonString);
I am developing a J2ME project with J2ME polish 2.4, using the json-1.0.jar library. The project was working not until I updated J2ME polish from 2.3 to 2.4
As we know J2ME Does not support java.util.Map so Json lib that you are using internally using java.util.Map so you should use json library for J2ME.
