FIGURE 11-1. The
simplemessage
Application
The source code for this application
is in the
tut-install
/examples/ejb/sim-
plemessage/
directory.
The
simplemessage
Application Client
The
SimpleMessageClient
sends messages to the queue that the
SimpleMes-
sageBean
listens to. The client starts by injecting the connection factory and queue re-
sources:
@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);
}
