wildfly JMS consumer gives null value

[Gulam Samdani]

I am doing a wildfy JMS program  . After running this program it gives "null value".

Please give me a solution.

package com.itbuzzpress.jms;

import java.util.Properties;

import javax.jms.ConnectionFactory;
import javax.jms.Destination;
import javax.jms.JMSConsumer;
import javax.jms.JMSContext;
import javax.jms.Queue;
import javax.naming.Context;
import javax.naming.InitialContext;

public class JMSClient2 {

    public static void main(String[] args) throws Exception {

        Context namingContext = null;
        JMSContext context = null;

        try {

            final Properties env = new Properties();
            env.put(Context.INITIAL_CONTEXT_FACTORY, "org.wildfly.naming.client.WildFlyInitialContextFactory");
            env.put(Context.PROVIDER_URL, "http-remoting://127.0.0.1:8080");
            env.put(Context.SECURITY_PRINCIPAL, "murad");
            env.put(Context.SECURITY_CREDENTIALS, "Murad@1234");
         
            namingContext = new InitialContext(env);

            ConnectionFactory connectionFactory = (ConnectionFactory) namingContext.lookup("jms/RemoteConnectionFactory");
           
           // Destination destination = (Destination) namingContext.lookup("jms/queue/exampleQueue");
           
            Queue destination = (Queue) namingContext.lookup("jms/queue/exampleQueue");
           
            context = connectionFactory.createContext("murad", "Murad@1234");
           
            JMSConsumer consumer = context.createConsumer(destination);

            String text = consumer.receiveBody(String.class, 9000);
            if (text == null)
             
            System.out.println("Received message with content " + text);

        } catch (Exception e) {
            System.out.println(e.getMessage());
            throw e;
        } finally {
            if (namingContext != null) {
                namingContext.close();
            }

            // closing the context takes care of consumer too
            if (context != null) {
                context.close();
            }
        }

    }
}

wildfy configuration is :
