Importing JSON into an Eclipse project

Question

I'm an aspiring Java programmer looking to use JSON in a project. I was following a programming tutorial (from a book) which asked me to import JSON into my project by using the following line:

import com.google.appengine.repackaged.org.json.JSONArray;  

But this produced an error, so I replaced it with this line:

import org.json.JSONArray; 

This also produces a (different) error:

The import org.json cannot be resolved

I think the problem is that I don't actually have the JSON library in my Eclipse workspace. How can I do this, so I can use the JSONArray? I found the website for JSON, but am not sure what to download or how or where to install it:

http://json.org/java/

Answer 1

Download the ZIP file from this URL and extract it to get the Jar. Add the Jar to your build path. To check the available classes in this Jar use this URL.

To Add this Jar to your build path Right click the Project > Build Path > Configure build path> Select Libraries tab > Click Add External Libraries > Select the Jar file Download

I hope this will solve your problem

Answer 2

You should take the json implementation from here : http://code.google.com/p/json-simple/ .

• Download the *.jar
• Add it to the classpath (right-click on the project, Properties->Libraries and add new JAR.)
