NoClassDefFoundError when using Java Coinbase API

I've simply downloaded an API .jar file of a Coinbase. I've created a project dynamic web project. I added successfully into a reference library that API.

Here is my simple program:

import com.coinbase.api.Coinbase;
import com.coinbase.api.CoinbaseBuilder;

public class Main {
    public static void main(String[] args){

        try {

            Coinbase cb=new CoinbaseBuilder()
            .withApiKey(System.getenv("My API KEY"), System.getenv("MY API SECRET"))
            .build();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

As i run this program, it says:

Exception in thread "main" java.lang.NoClassDefFoundError: com/fasterxml/jackson/core/type/TypeReference
    at com.coinbase.api.CoinbaseBuilder.build(CoinbaseBuilder.java:16)
    at Main.main(Main.java:11)

    at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
    at java.lang.ClassLoader.loadClass(Unknown Source)
    ... 2 more

Do I need to put something here? I'm did checked thrice, My API key is correct!

This question appears to be off-topic because it is about a generic Java error rather than a Bitcoin related issue, a solution already exists at: http://stackoverflow.com/questions/17973970/how-to-solve-java-lang-noclassdeffounderror

@GeorgeKimionis I disagree. It would probably be better asked on another site, but I don't think it's offtopic. – Nick ODell – 2014-11-30T15:49:01.320

@GeorgeKimionis However, thanks for finding that link. That could probably be an answer if you quoted one of the answers on that page. – Nick ODell – 2014-12-01T15:23:40.740

@NickODell please be my guest and use that link however you like. – George Kimionis – 2014-12-02T00:07:00.297
