Issue in connecting Apache Phoenix with node.js using npm jdbc package - node.js

Question

I am using node.js v6 LTS and the npm jdbc package to connect to Apache phoenix on hortonworks.
My code is as below:-
var JDBC = require('jdbc');
var jinst = require('jdbc/lib/jinst');
var jar1='/home/ashish/seed-project-phoenix/public/drivers/phoenix-core-4.7.0.2.5.6.0-40.jar';
var jar2='/home/ashish/seed-project-phoenix/public/drivers/phoenix-queryserver-client-4.7.0.2.5.6.0-40.jar';
var jar3='/home/ashish/seed-project-phoenix/public/drivers/hbase-client-1.1.2.2.5.6.0-40.jar';
if (!jinst.isJvmCreated()) {
// Add all java options required by your project here. You get one
//chance to setup the options before the first java call.
jinst.addOption("-Xrs");
// Add all jar files required by your project here. You get one chance to
// setup the classpath before the first java call.
jinst.setupClasspath([jar1,jar2,jar3]); // adding jars
}
var config = {
url:'jdbc:phoenix:ZK1,ZK2,ZK3:2181:/hbase-unsecure',
drivername: 'org.apache.phoenix.jdbc.PhoenixDriver'
};
var phoenixHbase = new JDBC(config);
phoenixHbase.initialize(function(err) {
if (err) {
console.log(err);
}
else{
console.log("connected to Apache phoenix ...");
}
});
But I am getting following errors:-
{ Error: Could not find class org.apache.phoenix.jdbc.PhoenixDriver
java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory

There should be no problem with the connection string according to me and all the jar files have been added in accordance with the version.
Phoenix version:- 4.7.0.2.5.6.0-40
Hbase version :- 1.1.2.2.5.6.0-40
If anybody has done anything similar, please give some direction.
