org.xeustechnologies.jcl.JarClassLoader ClassNotFoundException

I need to use two different versions of jar of same package in my code. So that i have used JarClassLoader to achieve the same

But I ended with ClassNotFoundException

I have given below my code

Below is the executable Main class file

import java.lang.reflect.Method;

import org.xeustechnologies.jcl.JarClassLoader;
import org.xeustechnologies.jcl.JclObjectFactory;
import org.xeustechnologies.jcl.JclUtils;

public class Sam {

    public static void main(String args[]) {
        try{
            JarClassLoader jcl = new JarClassLoader();
            jcl.add("/Users/sd/Downloads/hbase-1.2.6/lib/");
             Object obj1 = JclObjectFactory.getInstance().create(jcl, "sample.InsertData");
             Insert mig = JclUtils.cast(obj1, Insert.class);
            Thread.currentThread().setContextClassLoader(jcl);
            Method method = Insert.class.getMethod("insert", new Class[]{});
             method.invoke(mig, args);
        }catch(Exception e) {
            e.printStackTrace();
        }

        }    

}

InsertData.java

import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;

import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.hbase.HBaseConfiguration;
import org.apache.hadoop.hbase.TableName;
import org.apache.hadoop.hbase.client.Connection;
import org.apache.hadoop.hbase.client.ConnectionFactory;
import org.apache.hadoop.hbase.client.HTable;
import org.apache.hadoop.hbase.client.Put;
import org.apache.hadoop.hbase.client.Table;
import org.apache.hadoop.hbase.util.Bytes;

public class InsertData implements Insert{



    public  void insert() throws IOException {
        for (int j = 0; j < 1; j++) {

            Configuration config = HBaseConfiguration.create();

On executing Sam I ended with below java.lang.ClassNotFoundException
