Compiling the AsynchConsumer Client Example
Compiling the AsynchConsumer Client Example
The message listener, asynchconsumer/src/java/TextListener.java, follows these steps:
1. When a message arrives, the onMessage method is called automatically.
2. The onMessage method converts the incoming message to a TextMessage and displays its
content. If the message is not a text message, it reports this fact:
public void onMessage(Message message) {
TextMessage msg = null;
try {
if (message instanceof TextMessage) {
msg = (TextMessage) message;
System.out.println(
"Reading message: " + msg.getText());
} else {
System.out.println(
"Message is not a " + "TextMessage");
}
} catch (JMSException e) {
System.out.println(
"JMSException in onMessage(): " + e.toString());
} catch (Throwable t) {
System.out.println(
"Exception in onMessage():" + t.getMessage());
}
}
You will use the connection factory and destinations you created in
