session = conn.createQueueSession(false,javax.jms.Session.AUTO_ACKNOWLEDGE);
producer = session.createProducer(myQueue);
conn.start();
consignmentMessage = session.createTextMessage();
consignmentMessage.setText(content);
producer.send(consignmentMessage);

connection.start();
session = connection.createQueueSession(false,Session.AUTO_ACKNOWLEDGE);
Queue queue = session.createQueue(propLoader.getValue(QUEUE_NAME));
consumer = session.createConsumer(queue);
while(true){
Message message = consumer.receive();
processMessage(message);

Tools used
The tools used for developing and building the order placement application are:
...
- Select Deploy New link from the Console Navigation in the left.
- Load the <geronimo_home>/repository/org/apache/geronimo/modules/ge-activemq-rar/1.1.12-beta/ge-activemq-rar-1.1.12-beta.rar file to the Archive field.
- Load the Order/config/jms-resource-plan.xml file to the Plan input field.
- Press Install button. Make sure Start app after install is selected when this deployment happens
- Upon successful installation message, verify the deployment by traversing scrolling down to the JMS resources link. It will display the connection factory and two JMS queues.
