Fist: an explanation of difference between org.json.simple.JSONObject and org.json.JSONObject ??
Second: I have a code with org.json.JSONObject and org.json.JSONException. When I edit the code in eclipse ( JUNO) it resolves the type of JSONException and imports the package org.json.JSONException but when I run the project using maven in command line I have a problem ( JSONException cannot be resolved to a type). I tried to solve the issue by adding dependency to pom.xml like this :
<dependency>
<groupId>com.googlecode.json-simple</groupId>
<artifactId>json-simple</artifactId>
<version>1.1</version>
but I am not sure if it is the right one . I even download the jar of org. java-json.jar and add it to web deployement assembly but still the same error. Anyone can help ?
回答1:
org.json and org.json.simple are two different Java libraries, which are incompatible with each other. The fact that they have the same name is only a misleading coincidence.
To compare the two libraries:

org.json.simple = http://code.google.com/p/json-simple/
org.json = http://json.org/java
