The simplemessage Application Client

The SimpleMessageClient sends messages to the queue that the SimpleMessageBean listens to. The client starts by injecting the the connection factory and queue resources:

@Resource(mappedName="jms/ConnectionFactory")
private static ConnectionFactory connectionFactory;

@Resource(mappedName=”jms/Queue”)
private static Queue queue;

Next, the client creates the connection, session, and message producer:

connection = connectionFactory.createConnection();
session = connection.createSession(false,
    Session.AUTO_ACKNOWLEDGE);
messageProducer = session.createProducer(queue);

Finally, the client sends several messages to the queue:

message = session.createTextMessage();

for (int i = 0; i < NUM_MSGS; i++) {
    message.setText("This is message " + (i + 1));
    System.out.println("Sending message: " +
        message.getText());
    messageProducer.send(message);
}
