You will find here code for a  Sample Message Driven Bean along with the ejb-jar.xml and jboss.xml. The MDB, below, is listening to a queue named testQueue which comes configured as part of jboss(the configuration can be found in jbossmq-destinations-service.xml file).

SampleMDBean.java:

package sample;

import java.io.Serializable;
import java.util.HashMap;
import java.util.Map;

import javax.ejb.MessageDrivenBean;
import javax.ejb.MessageDrivenContext;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.ObjectMessage;


/**
 * Sample Message driven bean
 *
 */
public class SampleMDBean implements MessageDrivenBean, MessageListener {

    
    /**
     * Message driven context
     */
    private MessageDrivenContext messageDrivenContext;

    /**
     * 
     */
    public void ejbCreate() {

    }

    /**
     * @see javax.ejb.MessageDrivenBean#ejbRemove()
     */
    public void ejbRemove() {
        
    }

    /**
     * @see javax.ejb.MessageDrivenBean#setMessageDrivenContext(javax.ejb.MessageDrivenContext)
     */
    public void setMessageDrivenContext(MessageDrivenContext messageDrivenContext) {
        this.messageDrivenContext = messageDrivenContext;
    }

    /**
     * @see javax.jms.MessageListener#onMessage(javax.jms.Message)
     */
    public void onMessage(Message message) {
        //do some logic in this method
        System.out.println("Entered the onMessage method of MDB");
    }

} //end of MDB
