I struggled with this "simple" task for more experienced people, I was stuck for 2 days, now I need help. I changed everything around, as it is now, millions of times, finally, I came across this spring JMS tutorial .
What I want to do, send a message and receive it. I also read this book in chapter 8 on messaging. This really explains the 2 types of messages well, and there is a good example for the type publish-and-subscribe, but now an example for point-to-pointmessaging ( this is the one I need ).
I can send the message to the queue myself, but I don’t know how to get why I tried using this spring tutorial, here is what I still have:
RE-EDITED SENDER:
package quartz.spring.com.example;
import java.util.HashMap;
import java.util.Map;
import javax.jms.ConnectionFactory;
import javax.jms.Destination;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.Queue;
import javax.jms.Session;
import org.springframework.jms.core.MessageCreator;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.JmsTemplate102;
import org.springframework.jms.core.MessagePostProcessor;
public class JmsQueueSender {
private JmsTemplate jmsTemplate;
private Destination destination;
public void setConnectionFactory(ConnectionFactory cf) {
this.jmsTemplate = new JmsTemplate102(cf, false);
}
public void setQueue(Queue queue) {
this.destination = queue;
}
public void simpleSend() {
this.jmsTemplate.send(this.destination, new MessageCreator() {
public Message createMessage(Session session) throws JMSException {
return session.createTextMessage("hello queue world");
}
});
}
public void sendWithConversion() {
Map map = new HashMap();
map.put("Name", "Mark");
map.put("Age", new Integer(47));
jmsTemplate.convertAndSend("ReceiverQueue", map, new MessagePostProcessor() {
public Message postProcessMessage(Message message) throws JMSException {
message.setIntProperty("AccountID", 1234);
message.setJMSCorrelationID("123-00001");
return message;
}
});
}
}
RECEIVER:
package quartz.spring.com.example;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.TextMessage;
public class ExampleListener implements MessageListener {
public void onMessage(Message message) {
if (message instanceof TextMessage) {
try {
System.out.println(((TextMessage) message).getText());
}
catch (JMSException ex) {
throw new RuntimeException(ex);
}
}
else {
throw new IllegalArgumentException("Message must be of type TextMessage");
}
}
}

, ( ):
1 Locate a ConnectionFactory, typically using JNDI.
2 Use the ConnectionFactory to create a Connection.
3 Use the Connection to create a Session.
4 Locate a Destination, typically using JNDI.
5 Use the Session to create a MessageConsumer for that Destination.
