Hi,
I'm using:
- JBoss AS 4.2.0
- ActiveMQ 4.1.1
I tried to use ActiveMQ as message broker for my MDB. Somehow it is not run
properly. I got 2 problem :
1. 13:32:10,344 WARN [ManagementContext] Failed to start jmx connector: Cannot
bind to URL [rmi://localhost:1099/jmxrmi]: javax.naming.CommunicationException
[Root exception is java.rmi.ConnectIOException: error during JRMP connection
establishment; nested exception is:
java.net.SocketException: Software caused connection abort: recv failed]
Does anyone know what is the problem ?
2. It seems that my MDB only process (receive the event) when it was first time
deployed. The sequence :
a. Run JBOSS AS
b. Run client, send message to a queue
c. Deploy my MDB
d. My MDB can process the message
e. Run the client again
f. MDB do nothing, until, I redeploy the MDB again.
Client snippet :
InitialContext ic = new
InitialContext(System.getProperties());
//connect using active mq
ActiveMQConnectionFactory cf = new
ActiveMQConnectionFactory();
Queue queue =
(Queue)ic.lookup("activemq/queue/outbound");
ic.close();
System.out.println("Queue testQueue exists");
Connection connection = cf.createConnection();
Session sess =
connection.createSession(false,Session.AUTO_ACKNOWLEDGE);
MessageProducer sender = sess.createProducer(queue);
TextMessage msg = sess.createTextMessage("test
activemq4");
sender.send(msg);
connection.close();
MDB Snippet:
@MessageDriven(activationConfig = {
@ActivationConfigProperty(propertyName = "destinationType",
propertyValue = "javax.jms.Queue"),
@ActivationConfigProperty(propertyName = "destination",
propertyValue = "queue.outbound"),
@ActivationConfigProperty(propertyName = "acknowledgeMode",
propertyValue="Auto-acknowledge")})
public class HelloMDB implements MessageListener {
public void onMessage(Message arg0) {
try {
TextMessage tm = (TextMessage)arg0;
System.out.println("Hello I'm Message Bean, receive
msg: "+tm.getText());
} catch (JMSException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Does anyone know what happen ?
Is it because of deadlock in the queue (between producer and consumer) or ?
Sorry, I'm not so sure where should I ask this question, whether to ActiveMQ
forum, or JBoss.
Please help.
Thanks.
Regards,
Ferry
