JMS Connect Exception

Hi

I have written a small JMS program. Its attached along. Here instead of configuring the JNDI, I have used
Sun System Message Queue ConnectionFactory. When I run the program as a standalone java program, I am getting the following
error. I am missing something over here. Is anything else required to be configured. I had got this program in the net.

Could some one help me in finding the issue.

Thanks


import javax.jms.ConnectionFactory;
import javax.jms.Connection;
import javax.jms.Session;
import javax.jms.MessageProducer;
import javax.jms.MessageConsumer;
import javax.jms.Queue;
import javax.jms.Message;
import javax.jms.TextMessage;

public class HelloWorldMessage {

/**
* Main method.
*
* @param args not used
*
*/
public static void main(String[] args) {

try {

ConnectionFactory myConnFactory;
Queue myQueue;


//Step 2:
//Instantiate a Sun Java(tm) System Message Queue ConnectionFactory
//administered object.
//This statement can be eliminated if the JNDI code above is used.
myConnFactory = new com.sun.messaging.ConnectionFactory();


//Step 3:
//Create a connection to the Sun Java(tm) System Message Queue Message
//Service.
Connection myConn = myConnFactory.createConnection();


//Step 4:
//Create a session within the connection.
Session mySess = myConn.createSession(false, Session.AUTO_ACKNOWLEDGE);


//Step 5:
//Instantiate a Sun Java(tm) System Message Queue Destination
//administered object.
//This statement can be eliminated if the JNDI code above is used.
myQueue = new com.sun.messaging.Queue("world");


//Step 6:
//Create a message producer.
MessageProducer myMsgProducer = mySess.createProducer(myQueue);


//Step 7:
//Create and send a message to the queue.
TextMessage myTextMsg = mySess.createTextMessage();
myTextMsg.setText("Hello World");
System.out.println("Sending Message: " + myTextMsg.getText());
myMsgProducer.send(myTextMsg);


//Step 8:
//Create a message consumer.
MessageConsumer myMsgConsumer = mySess.createConsumer(myQueue);


//Step 9:
//Start the Connection created in step 3.
myConn.start();


//Step 10:
//Receive a message from the queue.
Message msg = myMsgConsumer.receive();


//Step 11:
//Retreive the contents of the message.
if (msg instanceof TextMessage) {
TextMessage txtMsg = (TextMessage) msg;
System.out.println("Read Message: " + txtMsg.getText());
}


//Step 12:
//Close the session and connection resources.
mySess.close();
myConn.close();

} catch (Exception jmse) {
System.out.println("Exception occurred : " + jmse.toString());
jmse.printStackTrace();
}
}
}

It looks like the message broker isn't running - or isn't listening on locahost:7676.
Is the message broker already started ?

thanks,

Rob
