class file for java.util.Map not found

Question

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

Answer 1

众所周知，J2ME不支持java.util.Map，因此您在内部使用的java.util.Map是Json lib，因此您应该对J2ME使用json库。
