public class JmsMessageController {
@Inject
private JmsMessageModel jmsMessageModel;
@Resource(mappedName = "jms/myQueue")
private Queue myQueue;
@Inject

private JMSContext context;
public String sendMsg() {
sendJMSMessageToMyQueue(jmsMessageModel.getMsgText());
return "confirmation";
}
private void sendJMSMessageToMyQueue(String messageData) {
context.createProducer().send(myQueue, messageData);
}
}
As we can see, all we had to do was to inject an instance of the
JmsMessageModel
class we developed earlier and add a simple method that will invoke the generated
sendJMSMessageToMyQueue()
method, passing the message text as a parameter.
Next, we need to modify the generated
index.xhtml
file to add a form binding the
msgText
variable of
JmsMessageModel
to a text field and a command button that
invokes the
sendMsg()
method when it is clicked. The code is as follows:
