java.lang.NoClassDefFoundError: com.ibm.ws.naming.util.CommonHelpers

Question

I am trying to access a jms queue configured on Websphere Application Server 8. But I am getting java.lang.NoClassDefFoundError: com.ibm.ws.naming.util.CommonHelpers Exception. Can anyone suggest a solution? Does any jar file needs to be added? I have already added -

com.ibm.ws.messagingClient.jar
com.ibm.ws.sib.client_ExpeditorDRE_8.0.0.jar
com.ibm.ws.sib.client.thin.jms_8.0.0.jar
com.ibm.xml.thinclient_8.0.0.jar

in classpath. You can find the code at How to set Context.INITIAL_CONTEXT_FACTORY? NoInitialContextException?

package com.jms.test;
import java.util.Hashtable;
import javax.jms.Queue;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
public class Demo {
public static void main(String[] args) throws NamingException {

    System.out.println("Start.....");
    Hashtable environment = new Hashtable();
    environment.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.websphere.naming.WsnInitialContextFactory");
    environment.put(Context.PROVIDER_URL, "iiop://localhost:2810");
    //String pUrl = System.getProperty(Context.PROVIDER_URL);
    //System.out.println("*******"+pUrl+"********");
    InitialContext ctx = new InitialContext(environment);
    Queue queue = (Queue) ctx.lookup("jms/inQueue");
    System.out.println("*** Queue is *** "+queue.toString());
}}

Try to add com.ibm.ws.admin.client_8.5.0.jar it is in the WebSphere\AppServer85\runtimes folder. CommonHelpers class is in that jar.
