This is my sender class:
private void sendJMSMessage(Object data) throws JMSException {
Connection con = null;
Session s = null;
try {
con = context.createConnection();
s = con.createSession(false, Session.CLIENT_ACKNOWLEDGE);
MessageProducer producer = s.createProducer(glassFishQueue);
ObjectMessage msg = s.createObjectMessage();
ArrayList list = new ArrayList();
list.add("name");
msg.setObject(p);
producer.send(msg);
}
And my Message-driven Bean:
public void onMessage(Message message) {
try {
ObjectMessage om = (ObjectMessage) message;
ArrayList al = (ArrayList) om.getObject();
System.out.println("Msg: " + al.get(0));
} catch (JMSException jex) {
System.out.println("Exception: " + jex);
}
I got the message sent from sender class but I need a message back from EJB to the sender. Im doing a web client with a table but I need to fill it getting the info from a database remotely, I really doesnt know what i should to use to do this, so if im doing right let me know or tell me any suggestion
Thank u
JMS is asynchronous, so it won't work in request-response style out of the box.
If you want to send a reply, one way is to use a separate queue. Your MDB can write the response to this second queue and your client can listen to this queue by creating a QueueReceiver.
Another way is to use QueueRequestor. From javadocs:
It creates a TemporaryQueue for the responses and provides a request method that sends the request message and waits for its reply.
