org.glassfish.jersey.server.ContainerException: java.lang.NoClassDefFoundError: org.testng.TestNG?

I have project in eclipse it's an WebService Project REST API's and i have also added another project in Configure Build path -> Add Project and i have added one another Project in my API method i am calling TestNGCreator class look below.
Basically this project uses jersey framework in java creating REST API and when i am calling any perticular method i.e. execute it will call another class which resides in another project i have added project in Build path of this project my other methods are working fine but when i am calling method from different project i having this error.
Do i need to declare some where that i am using this class and this method in POM.xml or some where else
I need to run the automation by calling this TestNGCreator.main(null);
my another project is automation project in java TestNGCreator class resides in automation project.By calling this method i need to call above class and when i am doing it i am getting error.

json-schema-validator NoClassDefFoundError: com/google/common/io/Closer

Solution: Add the guava dependency:
<dependency>
<groupId>com.google.guava</groupId>
<artifactId>guava</artifactId>
<version>18.0</version>
</dependency>
I'm trying to use the json-schema-validator over here: https://github.com/fge/json-schema-validator .
I'm using the following maven dependency:
<dependency>
<groupId>com.github.fge</groupId>
<artifactId>json-schema-validator</artifactId>
<version>2.2.5</version>
</dependency>
Here is a class I'm trying:
import java.io.IOException;
import com.fasterxml.jackson.databind.JsonNode;
import com.github.fge.jackson.JsonLoader;
public class JsonSchemaTest {
public static void main(String[] args) throws IOException {
JsonNode jsonNode = JsonLoader.fromString("{\"a\":1}");
}
}
And here is the error I'm receiving:

--- Edit:
If I change my maven version to 2.1.7, I can do JsonNode jsonNode = JsonLoader.fromString("{\"a\":1}"); but I cannot create the factory here without the same java.lang.NoClassDefFoundError: com/google/common/io/Closer error:

You have to import guava library in your project.

Getting NoClassDef Error for classes imported through Maven

I have a Maven project in Eclipse created through m2e. It obtains client libraries from a project on GitHub called alternator. The classes seem to be imported fine, in my project, but on running them, it shows a NoClassDefFound error. Here's the code and the error:
Code:

this.client = new AlternatorDBClient();
this.mapper = new DynamoDBMapper(this.client);
this.db = new AlternatorDB().start();
}
}

The AlternatorDBClient class is importing one or more classes which are not on your class path:
import com.amazonaws.*;
import com.amazonaws.handlers.HandlerChainFactory;
import com.amazonaws.http.ExecutionContext;
import com.amazonaws.http.HttpResponseHandler;

import com.amazonaws.transform.Unmarshaller;
import com.amazonaws.util.json.JSONObject;
import org.apache.commons.logging.Log;

You are somehow missing:
<dependency>

<artifactId>aws-java-sdk</artifactId>
</dependency>
as a dependency in your project pom. As AlexR stated, please post your pom.
