I am building a simple maven project. I used build path to add json as a third party library and also added it to web-inf library. In the end, i added the dependency in pom.xml. However, with all the effort above, i still get this exception. Any information and advice is appreciated!

below is the exception

SEVERE: Servlet.service() for servlet [sfmserver] in context with path [/mysfmovies] threw exception [Servlet execution threw an exception] with root cause
java.lang.ClassNotFoundException: org.json.JSONException

Below is the content of my pom.xml

you can solve this add the following dependency (http://mvnrepository.com/artifact/org.json/json/20080701)

<dependency>
   <groupId>org.json</groupId>
   <artifactId>json</artifactId>
   <version>20080701</version>
</dependency>
