I am trying to run a web application based on spring consisting of standalone AMQ & Tomcat. I am not able to see my message being produced/consumed anywhere. This is my code:

TopicSender
=========
import java.io.Serializable;

import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.ObjectMessage;
import javax.jms.Session;
import javax.jms.Topic;

import org.springframework.beans.factory.annotation.Required;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;

public class TopicMessageSender {
private JmsTemplate jmsTemplate;
private Topic topic;

public void produce(final Serializable object) {
System.out.println(“inside produce”);
this.jmsTemplate.send(this.topic, new MessageCreator() {
public Message createMessage(Session session) throws JMSException {
ObjectMessage mm = session.createObjectMessage();
mm.setObject(object);
return mm;
}
});
}

@Required
public void setJmsTemplate(JmsTemplate jmsTemplate) {
this.jmsTemplate = jmsTemplate;
}

@Required
public void setTopic(Topic topic) {
this.topic = topic;
}
}

TopicMessageListener1
==================
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.ObjectMessage;

public class TopicMessageListener1 implements MessageListener{

@Override
public void onMessage(Message message) {
try {
if (message instanceof ObjectMessage) {
ObjectMessage mapMessage = (ObjectMessage) message;
Object obj = mapMessage.getObject();
System.out.println(“Printing from Subs1″ obj);
}
} catch (Exception e) {
// handle exception
}
}
}

Employee
=========
import java.io.Serializable;
import java.util.Date;

public class Employee implements Serializable {
private static final long serialVersionUID = 1L;
String lName=”Garg”;
String fName=”Kshitiz”;
double salary = 25000;
Date hireDate = new Date();
String address=”Gurgaon”;
public String getlName() {
return lName;
}
public void setlName(String lName) {
this.lName = lName;
}
public String getfName() {
return fName;
}
public void setfName(String fName) {
this.fName = fName;
}
public double getSalary() {
return salary;
}
public void setSalary(double salary) {
this.salary = salary;
}
public java.util.Date getHireDate() {
return hireDate;
}
public void setHireDate(java.util.Date hireDate) {
this.hireDate = hireDate;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
}

Relevant config file settings
====================

tcp://localhost:61616

I am not able to figure out the exact problem. Can you please help me ?

This is one great example on JMS Spring. But i do have one error. It is not able to establish a connection with ReplyNotifier and show —

Caused by: java.lang.NoSuchMethodException: blog.mdp.ReplyNotifier.notifyMe(blog.mdp.RegistrationRequest)

So could you please help me with this?

if i run the activemq server,i got this exception, plz help me..

I am able to resolve the issues and getting a significant gain in performance by doing this:

bean id="connectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">

I modifIED the RegistrationConsole.java to test sending 1 million messages in a loop, but I got the following exception after hundreds of messages.
