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 ?

First up, thanks a lot for this (and other) interesting article!

I was wondering why you’re using the XBean approach instead of the Spring approach which is also mentioned in the link you posted. (http://activemq.apache.org/how-do-i-embed-a-broker-inside-a-connection.html)

Greetings from Belgium!

Great post! Like Mark said, I definitely think you’ll like the messaging support we’ve been working on for the upcoming RC1…makes this much easier. Another thing worth pointing out is that when I read your requirements, it made me think, “Why do we need JMS at all for something simple like this?”. It’s the same thought I had when working on some examples, and so we’ve also added an even simpler MessageTemplate that uses the “native” BlazeDS message destinations to be able to push messages from your Java code to any interested Flex clients.

Cheers,
Jeremy

But it’s all good now.

<jms-message-destination id=”fromJms” queue-name=”toFlex”/>

It will look for a “connectionFactory” bean name within the Spring configuration. Otherwise, you could add that attribute as well. And, if you prefer to reference a Spring-configured JMS Destination instance, you can replace ‘queue-name’ above with ‘jms-destination-ref’ instead.

Please try it out and let us know what you think. I’ll be looking forward to the next post

Regards,
Mark
