External jar cannot be resolved in eclipse in Ubuntu

I wrote a simple JsonParser code in java. I downloaded json jar file following this post. I included the jar file through,

Project Properties-> Java Build Path -> Libraries -> Add external jars

But still I get the error, "The import org.json.JSONObject cannot be resolved" for the import statements.

This is happening in my Ubuntu machine. But following the same steps, I am successfully able to include the jar and run my program in Windows. But I want it working in my Ubuntu machine. Should I do anything different ?

I have the jar file in the my project directory. It is also getting listed under Referenced Libraries in Package explorer.

[edit]: I did a ctrl + shift + O to organize imports in eclipse and the statements 

import org.json.JSONObject
import org.json.JSONArray
import org.json.JSONExceptiop

got changed to, 

import org.json.simple.JSONObject
import org.json.simple.JSONArray

with following error,

The constructor JSONArray(String) is undefined
The method length() is undefined for the type JSONArray
The method getJSONObject(int) is undefined for the type JSONArray

Looks like you downloaded the .jar from here:

http://code.google.com/p/json-simple/

whereas the imports you had were based on the .jar from here:

http://www.java2s.com/Code/JarDownload/java/java-json.jar.zip

The JSONArray from json-simple does not have a constructor that takes a single string. Switch .jar files or fix the constructor.
