org.json.simple.JSONObject VS org.json.JSONObject , JSONException cannot be resolved to a type
json, jsonexception, maven
Solution
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:
General comparison = http://www.rojotek.com/blog/2009/05/07/a-review-of-5-java-json-libraries/ org.json.simple = http://code.google.com/p/json-simple/ org.json = http://json.org/java
Problem
First: can someone provide an explanation of the differences 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> </dependency> ``` 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 deployment assembly but still the same error. Can anyone help ?
